艾比湖湿地干湿季土壤水分和土壤盐分空间异质性研究
|
摘要
以新疆艾比湖湿地为研究区,以野外调查和实验数据为基础,运用经典统计学、地统计学以及GIS相结合的方法研究了春秋两季艾比湖湿地表层土壤盐分和土壤水分的空间变异特征及主要影响因素。研究结果表明:1)研究区春秋两季的表层土壤水盐的空间分布均表现为强相关性,土壤盐分和土壤水分分布均符合正态分布,半变异函数符合一般的球状模型;2艾比湖湿地土壤含盐量春季总体表现为湖东南侧高于西北侧,秋季东北高于西南;3土壤含水量的春秋两季与含盐量的春秋两季分布大致相同,春季集中在东南部,秋季集中在东北部。分析认为,干旱区气候条件、地形地貌、水文地质以及人类活动是影响艾比湖湿地土壤水盐空间分布的主要原因。研究艾比湖水盐时空分布特征及其驱动机制,对于干旱区土壤盐渍化动态变化监测具有重要的理论和实践意义。
In this contribution,on the basis of field investigation and experimental data,integrate conventional statistics and geostatistics based on GIS are used to study spatio-temporal variation of the surface soil salt content and soil moisture content in spring and autumn and analyze the main influencing factors between the Ebinur lake wetlands.The results show that soil salt and soil water show strong spatial autocorrelation in dry and wet seasons in the study region.The soil salt content in the southeast of the study area is higher than that in northwest.Soil moisture content is more than October in May,Spring is concentrated in the southeast,in the fall it is concentrated in the northeast.These results suggest that arid climate,topography,hydrogeology and human activity is the main reason of the spatial distribution of soil water and salt.We conclude that study soil moisture and soil salt space-time distribution characteristics and its driving mechanism,the arid area soil salinization has important theory and practice of practical significance.
