| 摘 要： | 基于区域变量化理论,运用传统统计学和地质统计学方法,以张掖市城市湿地为研究区,定量分析湿地土壤盐分、pH值和含水量的空间异质性.结果表明:土壤盐分较高,呈一定的碱化趋势；盐分属于强变异程度,pH值属于弱变异程度,含水量属于中等变异程度；根据半方差函数理论模型分析,盐分受结构性因素较大影响表现为强空间相关性,pH值受随机...

| Abstract: | Theory based on regional variables,the use of traditional statistics and geostatistics to Zhangye City wetland study area,quantitative analysis of wetland soil salinity,PH value and the spatial heterogeneity of water content.The results showed that: the higher the soil salinity,showing a certain degree of alkaline trend;salinity variation is strong,PH value of the variation is weak,moderate degree of variation in moisture content;theoretical model based on semi-variogram analysis of the larger salt affected... |
