摘要

土壤中的水分是影响半干旱区作物生长的重要因素

由于自身的特点决定了其在空间分布上存在着变异性。以黑龙江省西部半干旱农业气候区的查哈阳农场为研究对象

利用GS 地统计软件和ArcGIS中的地统计分析模块(Geostatistical Analyst)

对该地区土壤水分特性的空间变异性进行分析

得出土壤水分特性的变异程度、影响因素以及空间分布图。借助于土壤水分特性的空间分布图对该地区的灌溉水量进行了分析

为该地区的合理灌溉和精确灌溉提供依据。

Abstract

Soil water is an important factor that affects the growth of crops in semiarid area and has variability at spatial distribution decided by its own characteristics.Based on Chahayang Farm in western semiarid agricultural climate area of Heilongjiang

the authors analyzed the spatial variability of soil water characteristics in this region by using geostatistics software GS and geostatistics analyst module in ArcGIS

elicited the variant degree

influencing factors and spatial distribution maps of soil water characteristics which was used to analyze irrigation water quantity and provide bases for reasonable and precise irrigation of this region.
