Analysis of the spatial variability of soil moisture and salinity in Ebinur Lake wetlands,Xin-jiang
摘要
Abstract
Systematic research of soil water and salt is commonly lack in previous studies for the Lake Ebinur, thus in this study, in order to reveal the spatial distribution characteristics of soil degradation degree in the Lake Ebinur wetland, by taking the lake side of a distance to the Lake Ebinur 5-15 km, a circle area of 160 km2 as research area. The spatial variability of soil salinity,pH and moisture in the surface layer( 0-20 cm) of in the circle sampling area of Lake Ebinur was analyzed by using traditional statis⁃tics and geo-statistics. The results indicated that the variation in salinity was moderate in the different directions. The soil moisture in the Northeast, Southeast and Southwest belongs to the medium variation intensity, while the northwest belongs to strong variabili⁃ty. The soil pH of different directions has weak variation. Except that the soil salinity of northwest follows with the spherical model, soil salinity, water content and pH in other different directions were in line with the Gaussian model. Soil salinity, water content and pH of different directions showed strong spatial autocorrelation, which were mainly affected by structural factors. Moran�s I coef⁃ficient analysis proved that soil salinity in the southwest, water content and pH was stronger in spatial correlation than that in the other directions. The natural factors including winds, drought, water scarcity, desertification, salinization, and human activities in⁃cluding diversion cofferdam, planting drought-resistant and salt-tolerant plants, were contributed to sampling area of Lake Ebinur <br> wetland spatial distribution of surface soil salinity, water content and pH. Soil in the Lake Ebinur wetland is mainly of saline-based type, followed by the type of severe salinization and more serious salinization.关键词
