近50年疏勒河流域降水空间分布规律研究

Study on Spatial Distribution of Precipitation of Shu Le River Basin in Past 50 Years

基于疏勒河流域水文站和雨量站的观测数据,建立了多年平均降水量和地形因子(包括纬度、经度、地形高程)的关系模型,根据该模型,利用Acrgis及Suffer平台绘制了疏勒河流域多年平均降水量等值线。研究表明:疏勒河流域降水量随纬度地带性和垂直地带性变化呈明显规律性分布,尤其与海拔关系密切相关。同时,降水量在疏勒河流域与黑河流域的平原区境内具有相似性分布。

Based on the observed data Shule River Basin hydrological stations and rainfall stations,the establishment of the average annual precipitation and topographic factors（ including latitude,longitude,terrain elevation） of the relational model,according to the model,using Acrgis and Suffer platform draws Shu Le River Basin annual average precipitation contours. Studies have shown that： Shule River Basin with latitude zonal precipitation and changes in vertical zones showed a regular distribution,particularly closely related to the altitude. Meanwhile,precipitation in the territory of the plains in Shule River Basin and the Heihe River Basin District with similar distribution.
