【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 regions in Henan Province and Jiangsu Province were selected as sample areas. Spatial granularity was introduced into the study of soil and surface water diversity, and the spatial distribution diversity index of dominant soil genera and rare soil genera was analyzed. The grain size response types of spatial distribution area index and length index of surface water were studied, and the correlation and stability of the indices were studied in order to analyze the correlation between soil and surface water in the formation of spatial distribution pattern. The results show that with the increase of spatial particle size, the spatial distribution diversity index of dominant and rare soil genera and the spatial distribution area index of surface water body all belong to the non-responsive type. The spatial particle size response type of spatial distribution length index of surface water body belongs to irregular type. There is a certain correlation between soil and surface water in spatial distribution, in which the correlation of soil and water resources in Linzhou is strong and the correlation is stable.
