| 摘 要： | 选取河南省和江苏省共6个典型区域作为研究样区,将空间粒度引入并应用于土壤和地表水体多样性的研究中,分析优势土属和稀有土属空间分布多样性指数、地表水体空间分布面积指数及长度指数的粒度响应类型,并研究指数间的相关关系及其稳定性,旨在分析土壤与地表水体在空间分布格局形成上的相关性。结果表明:随着空间粒度的增加,优势土属和稀有土属空间分布多样性指数及地表水体空间分布面积指数的空间粒度响应类型均属于无响应型,而地表水体空间分布长度指数的空间粒度响应类型属于无规律型;土壤和地表水体在空间分布上存在一定的关联性,其中林州市水土资源的关联性强且相关关系稳定。

| Abstract: | Six typical areas from Henan province and Jiangsu province were selected as the study cases.The study was conducted by using different types of spatial distribution diversity index and spatial grain size method to analyze the spatial distribution characteristics of soil and surface water body.The granularity response type of space distribution diversities of dominant soil genus (YDsF) and rare soil genus (YFsF),modified Shannon diversity area index (MSHDAI) as well as space distribution length index (MSHDLI) and the stability of correlation among the four indexes were also analyzed specifically.The results showed that as the size of space growing,YDsF,YRSF and MSHDAI of the response spatial granularity belonged to no-responsive type,while MSHDLI belonged to the irregular type.There was a certain correlation between the spatial distribution of soil and surface water body.Especially the correlation of soil and water resources in Linzhou city was strong and stable. |
