| 摘 要： | 基于GIS和地理统计学的理论、方法对所取观测井地下水位降幅数据进行空间分布特征分析。结果表明:数据服从正态分布,结构符合球状模型,空间数据存在东西方向和南北方向的二价函数趋势;地下水位降幅由北向南呈环状递减,最深降幅达30m,绿洲群大部分居于20～30m降幅之间,为地下水开采密集区,大于10m降幅的面积约69300hm2。利用Kriging最优内插法生成等值线图,可以更准确和直观地展示整个研究区的地下水资源状况、生态环境可能发生退化的区域及未来发展方向。

| Abstract: | In the paper, by integrative using GIS and Geostatistics, we analyzed the special distribution characteristic of groundwater downrange in arid area. Results showed that: data obeyed normal distribution characteristic,structure was up to spherical model, special data was second trend; Most of oases lied in 20-30metres of the downrange of groundwater depth which were decreased as circus from north to south in study area. The state of groundwater can be intuitively exhibited using Kriging interpolation to acquire isoclinic chart. Moreover, it can imply the future direction and region of the study area |
