西藏年降雨量气候要素数据集（1990-2015）

本数据集是1990年至2015年青藏高原地区气候要素数据集，记录了青藏高原25年来每五年的年降雨量空间分布变化情况。数据为tif栅格格式，空间分辨率为1公里，年降雨量单位为0.1毫米。该数据来源于青藏高原上的气象站点日观测数据，通过时间聚合计算和空间插值处理生成，该数据集作为一种重要的气候要素可用于研究青藏高原的年际降雨量变化与气候变化，作为青藏高原生态环境变化的气候背景，为城镇化与生态环境交互胁迫研究提供数据支撑。

This dataset is a climate factor dataset covering the Qinghai-Tibet Plateau from 1990 to 2015. It documents the spatial distribution changes of annual rainfall over the plateau at five-year intervals across the 25-year timeframe. The data is stored in TIFF raster format, with a spatial resolution of 1 km, and the unit of annual rainfall is 0.1 mm. Derived from daily observation data of meteorological stations on the Qinghai-Tibet Plateau, this dataset was generated via temporal aggregation and spatial interpolation processing. As an important climate factor dataset, it can be used to study interannual rainfall variations and climate change over the Qinghai-Tibet Plateau, serve as a climatic background for research on ecological and environmental changes in the plateau, and provide data support for studies on the interactive stress between urbanization and the ecological environment.
