资料稀缺地区主要水文特性分析——以哈密三道岭矿区为例

Data Analysis of MainHydrology Characteristic in Data Sparse Region——TakeThree Dao Ling Districts of Ha Mi as Example

本文主要分析资料稀缺地区——三道岭矿区内的降水、各河流径流和及该区的地表水资源。采用长短系列、水文比拟法对搜集到的短系列实测流资料进行修正。采用数理统计方法对降雨-径流双累计曲线进行了分析。按矩法计算Cv值,再以P～Ⅲ型曲线进行适线调整。此外,再运用参数等值线法量算多年平均降水量和多年平均年径流量。通过分析,得出哈密三道岭矿区水资源特点为:(1)资源型缺水;(2)地表水资源分布不均。

This text primarily analyzes main hydrology characteristic in data sparse region_ three dao ling Districts of Ha Mi.Such as precipitation, runoff volumes, ground water resource.It is obvious that the water resource of characteristic in Ha Mi san dao ling Districts are： （1）Lack of water resources;（2）asymmetrical distributing of ground water resource.
