中国地理概览 | China Geographic Overview

地形与地貌 / Terrain & Landscape

中国国土面积约960万平方公里，地形从西向东呈三级阶梯状下降：西部青藏高原（平均海拔4,000米以上）→中部高原盆地（黄土高原、四川盆地）→东部平原丘陵（华北平原、长江三角洲）。这一地形格局决定了中国的河流走向——长江、黄河均自西向东入海。

China covers ~9.6 million km², with terrain descending in three steps from west to east: the Tibetan Plateau in the west (avg. elevation 4,000m+) → central plateaus and basins (Loess Plateau, Sichuan Basin) → eastern plains and hills (North China Plain, Yangtze Delta). This topography determines river flow — both the Yangtze and Yellow Rivers run west to east to the sea.

气候多样性 / Climate Diversity

中国跨越热带、亚热带、温带、寒温带和高原气候五个气候带。海南岛全年温暖如夏，黑龙江冬季最低可达-40°C，新疆夏季高温超40°C，西藏高原紫外线强烈。旅行前务必了解目的地气候特点。

China spans five climate zones: tropical, subtropical, temperate, cold temperate, and plateau. Hainan Island is warm year-round; Heilongjiang can reach -40°C in winter; Xinjiang exceeds 40°C in summer; Tibet has intense UV radiation. Always research your destination's climate before traveling.
