克里雅绿洲浅层地下水特征与表层土壤特征的相互关系研究——基于最优插值预测
The Relationship between Characteristics of Shallow Groundwater and Surface Soil of Keriya Oasis Area——Based on the Optimal Interpolation Method
摘要
Abstract
Through prediction from point to surface in specific region,and studies on the spatial change regulation of shallow groundwater and surface soil characteristics,and their mutual effect in typical arid area,which had important significance on water and soil relation in arid area.This paper used the optimal spatial interpolating predicting method to forecast the whole status of shallow groundwater and surface soil in Keriya oasis,including groundwater depth,electrical conductivity,temperature and surface soil moisture content,electrical conductivity,temperature,and conducted correlation studies on all water and soil indexes at whole situation dimension.The results indicated that:①In Keriya oasis,the groundwater depth was mainly under 3 m,groundwater EC under 5 mS/cm,groundwater temperature under 15℃,water content of surface soil under 50％,surface soil EC under 2.5 mS/cm,surface soil temperature under 13℃.The spacial distribution of shallow groundwater characteristics and surface soil characteristics all present certain change rule.② Shallow groundwater characteristics and surface soil characteristics all have spatial and statistical correlation,groundwater conductivity and surface soil salinity have the best linear regression results (R2 =0.721 8).The equation y =0.144x+0.172 1 can be a reference frame in practical prediction.关键词
