中文摘要:

运用地统计学方法对干旱区平原水库坝口外侧周围的土壤盐分、有机质、pH值的空间变异性进行了分析.结果表明:土壤总盐平均含量高于土壤盐化标准(＞0.3％),并表现出由表层向底层递减的趋势.土壤有机质具有强烈的空间相关性,变异主要由内在区域性因素引起.土壤总盐和pH值均表现出中等强度的空间相关性.空间分布格局上,土壤盐分呈现出水库大坝附近含量高,离大坝越远盐分含量越低的分布规律.而有机质的空间分布与盐分的相反,即土壤有机质含量高的地方,盐分少.同时,pH空间分布格局总体上表现出盐高的地点,pH低的特点.

英文摘要:

Spatial variability of soil salinity,organic matter and pH value around the area at the mouth of reservoir dam on arid plain was analyzed by using the method of geostatistics.Results showed that total salt content is higher than the standard value by more than 0.3%,and decreases gradually from the surface to the bottom.Soil organic matter has a strong spatial correlation,variation is mainly caused by regional factors.Total salt and soil pH values showed moderate spatial correlation which is determined by th...
