地统计学在湿地土壤养分空间异质性研究中的应用

Application of Geo-statistics in Spatial Heterogeneity of Soil Nutrients in Wetlands

在地统计学的区域化变量理论和变异函数的基础上建立了一套对湿地土壤养分的空间异质性进行定量化的较系统且完整研究的方法,通过向海湿地的案例研究证实了该方法在湿地土壤养分空间异质性研究中具有较强的操作性和准确性。

Geostatistics is a new method of spatial analysis which is developed in recent years, its variograms is suited to research quantitatively characters of spatial structure variation of regionalized variable and capable of reflecting fully the constructive property of regionalized variable. In this paper the authors intend to research quantitatively the spatial heterogeneity of soil nutrients in wetlands by the theory of regionalized variable and variograms of geostatistics. Based on the theory of regionalized variables and variograms of geostatistics, the systematic and complete method on quantitative research on the spatial heterogeneity of soil nutrients in wetlands is established. A case study on Xianghai wetland confirms that it was efficient and accurate to study on the spatial heterogeneity of soil nutrients in wetlands.
