Basic datasets of the Tibetan Plateau in Chinese Cryospheric Information System

Chinese Cryospheric Information System is a comprehensive information system for the management and analysis of Chinese Cryospheric data. The establishment of Chinese Cryospheric Information System is to meet the needs of earth system science, to provide parameters and validation data for the development of response and feedback model of frozen soil, glacier and snow cover to global change under GIS framework; on the other hand, it is to systemically sort out and rescue valuable cryospheric data, to provide a scientific, efficient and safe management and division for it Analysis tools.The basic datasets of the Tibet Plateau mainly takes the Tibetan Plateau as the research region, ranging from longitude 70 -- 105 ° east and latitude 20 -- 40 ° north, containing the following types of data:1. Cryosphere data. Includes:Permafrost type (Frozengd), (Fromap);Snow depth distribution (Snowdpt)Quatgla (Quatgla)2. Natural environment and resources. Includes:Terrain: elevation, elevation zoning, slope, slope direction (DEM);Hydrology: surface water (Stram_line), (Lake);Basic geology: Quatgeo, Hydrogeo;Surface properties: Vegetat;4. Climate data: temperature, surface temperature, and precipitation.3. Socio-economic resources (Stations) : distribution of meteorological Stations on the Tibetan Plateau and it surrounding areas.4. Response model of plateau permafrost to global change (named "Fgmodel"): permafrost distribution data in 2009, 2049 and 2099 were projected.Please refer to the following documents (in Chinese): "Design of Chinese Cryospheric Information System.doc", "Datasheet of Chinese Cryospheric Information System.DOC", "Database of the Tibetan Plateau.DOC" and "Database of the Tibetan Plateau 2.DOC".

中国冰雪信息系统系一项综合性的信息管理系统，旨在对我国的冰雪数据实施管理与分析。该系统的构建旨在满足地球系统科学的需求，为全球变化下冻结土壤、冰川及积雪覆盖响应与反馈模型的开发提供参数及验证数据，基于地理信息系统（GIS）框架；另一方面，旨在对宝贵的冰雪数据进行系统性的整理与抢救，为其分析工具提供科学、高效且安全的管理与分配。西藏高原的基本数据集主要以青藏高原为研究区域，涵盖东经70°至105°、北纬20°至40°的范围内，包含以下类型的数据：1. 冰川圈数据。包括：永久冻土类型（Frozengd）、（Fromap）；积雪深度分布（Snowdpt）、第四纪冰川（Quatgla）。2. 自然环境和资源。包括：地形：海拔、海拔分区、坡度、坡向（DEM）；水文：地表水体（Stram_line）、（Lake）；基础地质：Quatgeo、Hydrogeo；地表特性：Vegetat。3. 气候数据：温度、地表温度和降水。4. 社会经济资源（站点）：青藏高原及其周边地区气象站点的分布。5. 高原永久冻土对全球变化的响应模型（命名为“Fgmodel”）：预测了2009年、2049年和2099年的永久冻土分布数据。请参阅以下中文文档：“中国冰雪信息系统设计方案.doc”、“中国冰雪信息系统数据表.DOC”、“青藏高原数据库.DOC”及“青藏高原数据库2.DOC”。
