守护欧洲的自然净土 Preserving Europe's wild places

三峰自然公园，意大利

“欧洲公园日”旨在庆祝欧洲大陆上的自然保护区，并纪念1909年欧洲首批国家公园的诞生。这一节日提醒着世人：现今诸多最具代表性的自然景观，皆得益于长期的生态保育努力。今日的影像向我们展示了这一文化遗产的典范——位于意大利北部的三峰自然公园。

该公园设立于1981年，坐落于多洛米蒂山脉之中。多洛米蒂山脉因其卓越的地质特征被列入《世界自然遗产名录》。公园内最负盛名的景观当属拉瓦莱多三峰（Tre Cime di Lavaredo）：这三座巍峨的白云岩峰丛，从高山草甸中拔地而起。其陡峭的绝壁使其成为了阿尔卑斯山脉辨识度最高的地标之一。

三峰自然公园的建立旨在保护脆弱的高山生态系统，在自然保育与适度开发之间寻求平衡。修缮良好的步道引导游客穿行于景观之中，而对开发建设的严格限制则有效地保护了本土野生动物及该地区原始荒野的面貌。“欧洲公园日”时刻提醒我们，唯有坚持将生态保护放在首位，这些圣地才能经久不衰。

European Day of Parks

The European Day of Parks celebrates protected areas across the continent, marking the creation of Europe's first national parks in 1909. It serves as a reminder that many of today's most iconic landscapes exist because of long-term conservation efforts. Today's image highlights a prime example of this legacy: Tre Cime Nature Park in northern Italy.

Located in the Dolomites—a UNESCO World Heritage Site known for striking geology—the park was established in 1981. It is best known for the Tre Cime di Lavaredo: three towering dolomite peaks that rise sharply above alpine meadows. Their sheer rock faces make them among the Alps' most recognizable landmarks.

Created to protect fragile alpine ecosystems, Tre Cime Nature Park balances preservation with carefully managed access. Well-maintained trails guide visitors through the landscape, and limits on development help safeguard native wildlife and the area's rugged character. European Day of Parks reminds us that these places endure because conservation remains a priority.

海洋生命的律动 The shape of life at sea

国际生物多样性日

每年5月22日为“国际生物多样性日”，它向全球发出提醒：地球上的生命远比肉眼所见更加丰富，却也更加脆弱。这一由联合国设立的纪念日，旨在强调保护动植物及其生态系统为何对粮食安全、药物研发、气候稳定以及人类的日常福祉至关重要。

鲜有地方能像法属波利尼西亚土阿莫土群岛的考埃希环礁（如图中俯瞰所示）这样，如此清晰地展示地球的奥秘。其纤细的珊瑚环带围合出一片广阔的碧色泻湖，这是由活体珊瑚礁与避风洋流历经数千年雕琢而成的杰作。作为法卡拉瓦生物圈保护区的重要组成部分，考埃希的生态系统承载着繁茂的珊瑚群落、鱼类育幼场、海鸟以及适应了海天之间极端生境的岛屿植被。

几个世纪以来，波利尼西亚航海家们早已深谙这种生态平衡之道，将健康的泻湖与礁石视为生存与文化的基石——这种纽带至今仍映照在环礁的日常之中。在“国际生物多样性日”之际，考埃希环礁这样的景观提醒着我们：守护自然，不仅是在保护生物物种，更是在守护全人类共享的文化记忆与未来。

International Day for Biological Diversity

Observed each year on May 22, International Day for Biological Diversity is a global reminder that life on Earth is richer—and more fragile—than it appears. Established by the United Nations, today highlights why protecting plants, animals, and ecosystems matters for food, medicine, climate stability, and everyday well-being.

Few places reveal our planet's secrets with such clarity as Kauehi Atoll, seen here from above in the Tuamotu Archipelago of French Polynesia. Its thin coral ring encloses a vast turquoise lagoon, shaped over millennia by living reefs and sheltered currents. Kauehi's ecosystem is part of Fakarava Biosphere Reserve and supports coral communities, fish nurseries, seabirds, and island vegetation adapted to life between ocean and sky.

For centuries, Polynesian navigators understood this balance, relying on healthy lagoons and reefs for survival and culture—a relationship still reflected in the atoll today. On International Day for Biological Diversity, landscapes like Kauehi remind us that safeguarding nature protects stories, cultures, and futures across our shared planet.

酿造传承 Brewing a legacy

国际茶日

“国际茶日”旨在礼赞一种将日常习俗与古老地貌紧密相连的饮品。只需瞥一眼中国四川省那层层叠叠的梯田茶园，便不难领略其深植的文化根基。这片位于中国西南部的云雾缭绕之地，乃是茶文化的早期发源地之一；早在两千多年前，当地居民便已在此饮茶、植茶。在邻近的蒙顶山上，一位名叫吴理真的学者曾在汉朝时期开辟了世界上首批人工管理的茶园，从而为后世一代又一代的茶农奠定了坚实的基础。

这些陡峭的梯田并非仅仅为了美观而建。它们帮助农民调控雨水、保护脆弱的土壤，并亲手采摘那些日后将远销四川境外的嫩叶。数百年来，产自这些山丘的收成沿着崎岖的商贸古道运往西藏，由背夫们翻山越岭、一路背负前行。“国际茶日”已获联合国认可，旨在彰显茶饮深厚的文化底蕴，并突显那数百万个与每一杯茶息息相关的生计——无论这杯茶是冲泡于寻常百姓家中，还是种植于巍峨的山坡之上。

International Tea Day

International Tea Day celebrates a drink that connects daily rituals to ancient landscapes. Just one look at the terraced tea fields of Sichuan Province, China, shows how deep those roots run. This misty region in southwest China is one of the earliest centers of tea culture, where people drank and cultivated tea more than 2,000 years ago. On nearby Mengding Mountain, a scholar named Wu Lizhen planted some of the world's first managed tea gardens during the Han Dynasty, laying the groundwork for generations of growers.

The steep terraces weren't built for beauty alone. They helped farmers manage rainfall, protect fragile soil, and hand-pick tender leaves that later traveled far beyond Sichuan. For centuries, harvests from these hills moved along rugged trade routes toward Tibet, carried by porters across mountain passes.

Recognized by the United Nations, International Tea Day highlights the beverage's cultural legacy and the millions of livelihoods tied to every cup—whether brewed at home or grown on a mountainside.

马略卡岛的边缘 The edge of Mallorca

福门托尔灯塔, 马略卡, 巴利阿里群岛, 西班牙

在西班牙巴利阿里群岛中马略卡岛（Mallorca）的最北端，福门托尔灯塔（Formentor Lighthouse）巍然屹立于福门托尔角（Cap de Formentor）的陡峭悬崖之上。这处地势开阔的海角常被称为“风之汇聚地”。这座灯塔始建于1863年，并于当年9月30日首次点亮，它高耸于地中海海面近700英尺之上；若要抵达此处，需沿着一条狭窄蜿蜒的盘山公路前行，全程约8英里，起点位于波连萨港（Port de Pollença）。脚下是色泽浅淡的石灰岩——这些岩石由远古海洋生物遗骸历经漫长岁月沉积而成，随后在地壳运动的抬升与风化侵蚀的雕琢下，演化为如今这般气势磅礴的峭壁、海蚀洞穴及天然拱门。正是这种崎岖险峻的地质地貌，造就了该地区那种苍凉壮阔的独特美感与遗世独立的孤寂氛围。想要将这绝美景色尽收眼底吗？不妨沿着半岛上的徒步路线前行，或者挑战一段短促却陡峭的登高之路，攀至阿尔贝库奇瞭望塔（Talaia d'Albercutx）俯瞰全景，随后再继续前往灯塔。攀登途中请留意山坡：那些由早期家养羊群野化而来的野生山羊，正凭借着天生的平衡感，在险峻的岩架之间轻盈自如地跳跃穿梭。

Formentor Lighthouse, Mallorca, Balearic Islands, Spain

At Mallorca's far northern tip, in Spain's Balearic Islands, the Formentor Lighthouse stands on the sheer cliffs of Cap de Formentor. This exposed headland is often called the 'Meeting of the Winds.' Built in 1863 and first lit on September 30 of that year, the lighthouse rises nearly 700 feet above the Mediterranean Sea and is reached by a narrow, switchback road about 8 miles from Port de Pollença. Under your feet is pale limestone—rock formed from ancient marine life and later lifted and carved by erosion into dramatic faces, sea caves, and natural arches. This rugged geology gives rise to the area's stark beauty and sense of isolation. Want to earn the view? Follow one of the peninsula's hiking routes, or tackle the short, steep climb to Talaia d'Albercutx for a watchtower panorama before continuing to the lighthouse. Keep an eye on the slopes: wild goats, descended from early domestic herds, spring across the ledges with effortless balance.

大厅里的希望 Hope in the hall

国际博物馆日

当你步入博物馆，时光仿佛瞬间流转。一枚化石，诉说着数百万年前生命的印迹；一颗宝石，映照着肉眼难见的沧海桑田。正是这种深切的联结感，构成了“国际博物馆日”——这一由国际博物馆协会于1977年创立的节日——所旨在颂扬的核心精神。

位于伦敦的自然历史博物馆始建于1881年，步入其中，那些令人惊叹的时刻便会接踵而至。这座建筑采用罗马式复兴风格，其设计巧妙地融入了自然形态；馆内展区则划分为四个以颜色区分的区域，按主题对展厅进行了归类。如今，馆内收藏着逾8000万件标本，涵盖植物学、动物学、矿物学及古生物学等多个领域。其中，博物馆的恐龙展厅以及悬挂在欣策大厅（Hintze Hall）上方、名为“希望”（Hope）的巨型蓝鲸骨架，堪称该馆最具代表性的展品。

究竟是什么吸引着人们——是好奇心，还是怀旧情怀？博物馆将抽象的概念转化为触手可及的实物，供你亲眼观赏并探究追问。从科学纪录片到《博物馆奇妙夜》一类的电影，它们都在提醒我们：探索之旅绝非止步于教科书之中——当你迈入博物馆大门的那一刻，真正的探索才刚刚开始。

International Museum Day

You walk into a museum, and suddenly time shifts. A fossil hints at life millions of years ago. A gemstone reflects geological change you can't see. That sense of connection is exactly what International Museum Day, created in 1977 by the International Council of Museums, aims to celebrate.

At the Natural History Museum in London, which opened in 1881, those moments come quickly. Built in Romanesque Revival style, the building reflects natural forms in its design, while four color-coded zones organize the galleries by theme. Today, it houses over 80 million specimens, spanning botany, zoology, mineralogy, and paleontology. The museum's dinosaur gallery and the massive blue whale skeleton , named Hope, suspended in Hintze Hall, are among its most recognized displays.

What draws people in—curiosity or nostalgia? Museums turn abstract ideas into real objects you can see and question. From science documentaries to films like 'Night at the Museum,' they remind us that exploration doesn't end in textbooks—it starts when you walk through the door.

静谧之巅，喧嚣之景 Quiet peak, loud view

仙纳度国家公园的玳瑁峰, 弗吉尼亚州

究竟要多高，才能尽享绝佳美景？在美国东部，其实无需太高的海拔。位于弗吉尼亚州仙纳度国家公园（Shenandoah National Park）内的玳瑁峰（Hawksbill Mountain），海拔仅为4050英尺；这充分表明，对于这些古老的山脉而言，开阔的视野远比绝对的高度更为重要。该公园成立于1935年，其建立过程伴随着大规模农耕与伐木活动之后的植被恢复工作。如今，昔日的土地大都已重披林装，孕育着混交阔叶林、山月桂以及杜鹃花等丰富的植被。此外还有什么值得一提？公园内的部分岩石距今已逾10亿年，堪称该州最为古老的岩层之一。这里栖息着200多种鸟类和32种鱼类；同时，公园对宠物也十分友好，允许游客携带爱犬进入露营地及大多数步道。

玳瑁峰（Hawksbill）的峰顶并非由陡峭的悬崖构成；取而代之的是，一座由“平民保护团”（Civilian Conservation Corps）于20世纪30年代修建的石质平台标志着这里的最高点。从此处眺望，连绵的山脊向远方层层延伸，呈现出柔和的淡蓝色调——这一景象正是由大气散射效应所致。“天际线公路”（Skyline Drive）将游客引向通往此类山峰的各处登山步道起点。

Hawksbill Mountain in Shenandoah National Park, Virginia

How high is high enough for a great view? In the eastern United States, it doesn't take much. Hawksbill Mountain is the highest point in Shenandoah National Park, Virginia, at 4,050 feet, showing how these older mountains rely on openness, not elevation. The park's establishment in 1935 involved reforestation after extensive farming and logging. Today, much of that land has returned to forest, supporting mixed hardwoods, mountain laurel, and rhododendron. What else? Some of the rocks found here date back over 1 billion years, among the oldest in the state. The park shelters over 200 bird species and 32 species of fish and remains dog friendly, allowing pets in campgrounds and on most trails.

Hawksbill's summit does not rely on steep cliffs. Instead, a stone platform built in the 1930s by the Civilian Conservation Corps marks the top. From here, ridges stretch into the distance in soft blue layers, an effect caused by atmospheric scattering. Skyline Drive connects visitors to trailheads leading to peaks like this.

一场穿越时空的旅程 A journey through time

皮蒂利亚诺, 托斯卡纳, 意大利

皮蒂利亚诺坐落在意大利托斯卡纳南部的一处凝灰岩山脊上，是一座小巧却个性十足的城镇。它的历史可以追溯到伊特鲁里亚时代，蜿蜒的街道至今仍回荡着昔日的痕迹，从中世纪的防御工事到文艺复兴时期的宫殿，处处可见历史的印记。漫步在狭窄的巷弄中，仿佛能感受到几个世纪的生活印记镌刻在石头上，而小巧的广场则邀请您驻足，品尝咖啡或意式冰淇淋。这座经久不衰的宝藏常被誉为“小耶路撒冷”，因为它拥有历史悠久的犹太区，那里有一座犹太教堂和一座古老的墓地，诉说着曾经繁荣的犹太社区的故事。

当地的小餐馆供应经典的托斯卡纳菜肴，从浓郁的野猪肉宽面到香滑的佩科里诺奶酪，每一餐都是品味当地风味的绝佳机会。小镇的独特魅力源于其历史、建筑和日常生活的完美融合——熙熙攘攘的市集摊位、悠扬的教堂钟声以及当地人的谈笑声。即使只是在皮蒂利亚诺短暂漫步，也能仿佛穿越时光，感受文化、美食和漫步的乐趣自然交织在一起。

Pitigliano, Tuscany, Italy

Perched on a tufa ridge in southern Tuscany, Italy, Pitigliano is a small town with a big personality. Its roots stretch back to Etruscan times, and the winding streets still echo the past, from medieval fortifications to Renaissance palaces. Walking through its narrow alleys, you can feel centuries of life carved into the stone, while small piazzas invite pauses for coffee or gelato. This enduring treasure is often called 'Little Jerusalem' for its historic Jewish quarter, where a synagogue and historic cemetery tell stories of a once-thriving community.

Local trattorias serve classic Tuscan dishes, from rich pappardelle with wild boar to creamy pecorino cheeses, making every meal a chance to savor the region. The town's flair comes from its combination of history, architecture, and everyday life—market stalls, church bells, and the chatter of locals. Even a brief stroll through Pitigliano turns into a journey through time, where culture, cuisine, and the simple joy of walking intertwine naturally.

拱门与银河, 阿拉巴马山, 内华达山脉, 加利福尼亚州

在今天这张照片中，阿拉巴马山的花岗岩拱门将银河框入加州东部内华达山脉崎岖的地貌之中。这片区域以其圆润的巨石和风化的岩层而闻名，大约在1亿年前由火山活动形成。水和风逐渐将岩石塑造成如今光滑的形状。游客可以探索天然拱门，在岩石间徒步，拍摄独特的景观，骑马或骑山地自行车，并欣赏季节性的野花盛开。

由于光污染极少，这些山丘是观星和夜间摄影的热门地点。在晴朗的夜晚，构成我们银河系的密集星带肉眼可见。虽然如今这里看起来像一片宁静的沙漠，但这片地形却在银幕上扮演过许多角色。自20世纪20年代以来，数百部电影和电视剧都曾以这些山丘为背景，拍摄西部片和科幻冒险片，其中包括格里高利·派克主演的《黄沙》、昆汀·塔伦蒂诺执导的《被解救的姜戈》以及乔恩·费儒执导的漫威经典之作《钢铁侠》。

Arch and Milky Way, Alabama Hills, Sierra Nevada, California

In today's image, the granite arches of the Alabama Hills frame the Milky Way over a rugged landscape in California's eastern Sierra Nevada. Famous for its rounded boulders and weathered rock formations, this area formed when molten rock cooled deep underground around 100 million years ago. Water and wind gradually shaped the stone into the smooth shapes seen today. Visitors can explore the natural arches, hike among the rocks, capture photographs of the unique landscape, ride horses or mountain bikes, and enjoy seasonal displays of wildflowers.

With minimal light pollution, the hills are popular for stargazing and night photography. On a clear night, the dense band of stars that forms our galaxy is visible to the naked eye. While it might look like a peaceful desert today, this terrain has played many roles on screen. Since the 1920s, hundreds of movies and television shows have used these hills as a backdrop for westerns and sci-fi adventures, including 'Yellow Sky' with Gregory Peck, 'Django Unchained' by Quentin Tarantino, and the Marvel classic 'Iron Man' by Jon Favreau.

世界最伟大的自然奇观之一，绵延在澳大利亚东北海岸线外的珊瑚海碧绿海水中。大堡礁沿着昆士兰海岸延伸，是世界上最大的珊瑚礁系统。它由近3000个独立的珊瑚礁和数百个岛屿组成，绵延超过1400英里。

这片非凡的海洋景观孕育着极其丰富的生物多样性，包括数百种珊瑚、超过1600种鱼类，以及海龟、鳐鱼、海鸟和礁鲨。其浅水泻湖、珊瑚礁岛和较深的外礁交错分布，构成了一幅地球上其他任何地方都无法比拟的壮丽景观。

作为联合国教科文组织世界遗产，这片珊瑚礁不仅因其规模和美景而备受珍视，更因其重要的生态意义以及与澳大利亚原住民深厚的文化联系而熠熠生辉。如今，研究人员、社区和政府携手合作，共同保护这片脆弱的生态系统，致力于为子孙后代守护珊瑚礁复杂的生态格局和生机勃勃的海洋生物。

Great Barrier Reef from above, Queensland, Australia

One of the world's greatest natural wonders stretches through the turquoise waters of the Coral Sea off Australia's northeast shoreline. The Great Barrier Reef, running along the coast of Queensland, is the world's largest coral reef system. It is made up of nearly 3,000 individual reefs and hundreds of islands, spanning more than 1,400 miles.

This remarkable marine landscape supports extraordinary biodiversity, including hundreds of coral species, more than 1,600 kinds of fish, as well as sea turtles, rays, seabirds, and reef sharks. Its shallow lagoons, coral cays, and deeper outer reefs create a mosaic found nowhere else on Earth.

Recognized as a UNESCO World Heritage Site, the reef is valued not only for its size and beauty, but also for its ecological importance and deep cultural connections to Australia's First Nations peoples. Today, researchers, communities, and governments work together to protect this fragile ecosystem, helping preserve the reef's complex patterns and vibrant marine life for the future.

克尔卡国家公园的斯克拉丁斯基布克瀑布, 克罗地亚

水是克罗地亚克尔卡国家公园的缔造者，它沿着克尔卡河塑造了碧绿的水潭和层叠的瀑布。今天的照片重点展示了公园最著名的瀑布群——斯克拉丁斯基布克瀑布，多条溪流从洛佐瓦茨村附近茂密森林中的石灰华梯田倾泻而下。

斯克拉丁斯基瀑布并非单一的瀑布，而是绵延近半英里、由17级台阶组成的宽阔瀑布群。富含矿物质的水流经苔藓和岩石，缓慢形成层层阶梯，最终塑造了河流的自然走向。木栈道横跨水面，使游客可以近距离欣赏奔腾的瀑布、星罗棋布的小岛以及曾经为当地社区提供动力的修复水磨坊。

除了瀑布群之外，克尔卡国家公园还保护着一系列天然水域和野生动物栖息地，使其成为克罗地亚最具特色的景观之一——在这里，运动、历史和地质仍然紧密交织在一起。

Skradinski Buk Waterfall, Krka National Park, Croatia

Water is the architect of Krka National Park in Croatia, shaping emerald pools and layered waterfalls along the Krka River. Today's image highlights Skradinski Buk, the park's most famous waterfall system, where multiple streams spill over travertine terraces in a dense forest near the village of Lozovac.

Skradinski Buk is not a single waterfall, but a wide cascade of 17 steps stretching nearly half a mile. These terraces form when mineral-rich water flows over moss and stone, slowly creating natural barriers that reshape the river's course. Wooden walkways cross the water, offering close-up views of rushing falls, small islands, and restored watermills that once powered local communities.

Beyond the waterfall complex, Krka National Park protects a network of natural waters and wildlife habitats, making it one of Croatia's most distinctive landscapes—where movement, history, and geology remain deeply intertwined.
