青海省自然灾害统计数据（1950-2000）

本数据集包含青海近50年的自然灾害信息，包括干旱、洪灾、冰雹、连阴雨、雪灾、寒潮和强降温、低温冻害、大风沙尘暴、虫灾、鼠灾、地质灾害等自然灾害产生的时间地点及所造成的后果。
青海省地处青藏高原东北部，总面积72 万平方千米。境内河流纵横，冰川广布，湖泊众多，因中华民族的两条母亲河长江、黄河及著名国际河流澜沧江发源于此而素有"中华水塔"之称;全省有可利用草地33.5 万平方千米，天然草场面积仅次于内蒙古、西藏和新疆而居全国第四位，草场类型多样，草地资源十分丰富，拥有青藏高原独特气候条件下生长发育的、并对高原生态环境特征具有较强代表性的维管束植物113 科、564 属、2100 种左右。青海省作为青藏高原的主体部分，是我国生物物种形成、演化的中心之一，也是国际科技界瞩目的研究气候和生态环境变化的敏感区和脆弱带。青海境内地形、地貌复杂，高山、谷地、盆地交错，多年积雪、冰川、戈壁、沙漠、草原等广有分布。复杂的地形条件，高峻的海拔高度和严酷的气候条件决定了青海是一个气象灾害十分频繁的省份。其主要的气象灾害有干旱、洪灾、冰雹、连阴雨、雪灾、寒潮和强降温、低温冻害、大风沙尘暴等。

This dataset contains information on natural disasters in Qinghai over the past 50 years, including the time, location and consequences of disasters such as drought, flood, hail, continuous rainfall, snow disaster, cold wave and strong cooling, low-temperature freezing injury, gale and sandstorm, insect disaster, rodent disaster and geological disaster.

Qinghai Province is located in the northeastern part of the Qinghai-Tibet Plateau, with a total area of 720,000 square kilometers. The province has crisscrossing rivers, widely distributed glaciers and numerous lakes. It is known as the "Water Tower of China" because the two mother rivers of the Chinese nation, the Yangtze River and the Yellow River, as well as the famous international river Lancang River, all originate here. The province has 335,000 square kilometers of usable grassland; its natural grassland area ranks fourth in China, only behind Inner Mongolia, Tibet and Xinjiang. With diverse grassland types and abundant grassland resources, Qinghai is home to approximately 2,100 species of vascular plants belonging to 564 genera in 113 families, which grow under the unique climatic conditions of the Qinghai-Tibet Plateau and strongly represent the ecological environment characteristics of the plateau.

As the main part of the Qinghai-Tibet Plateau, Qinghai is one of the centers for the formation and evolution of biological species in China, as well as a sensitive and fragile area that attracts widespread attention from the international scientific community for research on climate and ecological environment changes.

The topography and landforms in Qinghai are complex, with staggered mountains, valleys and basins, and widely distributed perennial snow, glaciers, Gobi deserts, sand deserts and grasslands. The complex terrain, high altitude and harsh climatic conditions make Qinghai a province with extremely frequent meteorological disasters. Its main meteorological disasters include drought, flood, hail, continuous rainfall, snow disaster, cold wave and strong cooling, low-temperature freezing injury, gale and sandstorm, etc.

This dataset is extracted from *The Canon of Chinese Meteorological Disasters · Qinghai Volume*, and was manually entered, summarized and proofread.
