摘要
为研究喀什噶尔河流域灌区土壤盐分空间分布特征。本文通过野外取样及测试,运用传统统计学和地统计学相结合的方法对喀什噶尔河流域灌区土壤盐分的空间分布特征及其影响因素进行分析。结果表明:研究区内不同深度土壤含盐量均属强变异性,其空间变异格局受随机性和结构性因素共同影响,各层土壤含盐量均表现为由西向东先增加后减小,其空间分布特征在喀什三角洲较为复杂,盐渍化影响因素众多,其中地下水对盐渍化的影响较大。
The objectives of this paper were to study the spatial distribution characteristics of soil salinity in the irrigation area of the Kashgar River basin.Through field sampling and testing,this paper analyzes the spatial distribution characteristics and influencing factors of soil salinity in the irrigation area of Kashgar River basin by combining traditional statistics and geostatistics.The results showed that the soil salt content at different depths in the study area was highly variable,and its spatial variation pattern was affected by both randomness and structural factors;The soil salinity of each layer increased first and then decreased from west to east,and its spatial distribution characteristics were complex in Kashgar Delta.There are many influential factors of the salinization,among which groundwater have a greater impact on salinization.
