基于空间统计分析的柴达木盆地大格勒灌区土壤水分变化特征与监测点优化布置研究
Study on the Characteristics of Soil Moisture Change and the Optimal Arrangement of Monitoring Points in the Dagele Irrigation District in the Qaidam Basin Based on Spatial Statistical Analysis
摘要
Abstract
In order to analyze the spatial relationship of soil moisture monitoring points in precise irrigation of farmland,and determine the lo-cation and quantity of soil moisture monitoring points,this paper took the Dagele Irrigation District in the Qaidam Basin as the research object.The spatial autocorrelation analysis Moran's I index tool and spatial interpolation method were adopted,based on field experiments in the irri-gation area,the spatial variability of soil moisture was analyzed,and the rational spatial distribution and number of soil moisture monitoring points in the experimental area were explored.According to the spatial autocorrelation analysis,the monitoring points of soil moisture should be located at the average value of soil moisture,the monitoring depth should be controlled at 0-40 cm,and the distance between monitoring points should be controlled at about 299 m.The research results can provide references for the arrangement of soil moisture monitoring points.关键词
