克拉玛依农业开发区地下水埋深与土壤积盐空间异质性分析
Spatial Distribution Pattern Quantitative Analysis of Soil Salt Accumulation and Groundwater Depth in the Karamay Agricultural Development Zone
摘要
Abstract
[ Objective ] Analyzing the regularity of soil salt accumulation in plough layer caused by groundwater is order to study the formative reason of soil salinization and constitute improved countermeasure in the agricultural development zones of Karamay. [ Method ]GIS and methods of geostatistics were applied to regionalize the study area based on the spatial distribution pattern of groundwater table. [Result] Quantitative a-nalysis was performed. Results of the soil salinity distributing features indicate that groundwater depth, soil salt content all exhibit moderate spatial variation. Soil salt content of the middle and bottom layer exhibits strong variation. Owing to compound impact of structural and stochastic factors, groundwater table and the soil salt content of bottom layer exhibit strong spatial autocorrelation while the soil salt content of tilth soil and middle layer have obvious spatial autocorrelation. The quantitative analysis of groundwater and soil salinity in plough layer, which is performed at the spatial scale, shows that the soil salt content of tilth soil and bottom layer is negatively correlated with the depth of the water while middle layer and groundwater depth have no obvious correlation. [ Conclusion] The current saline improved main measures is to control and reduce the underground water level. Governor must strengthen drainage, formulate reasonable irrigation quota and strictly implement .关键词
