| Abstract: | 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. |
