【摘要】:選取河南省和江蘇省共6個(gè)典型區(qū)域作為研究樣區(qū),將空間粒度引入并應(yīng)用于土壤和地表水體多樣性的研究中,分析優(yōu)勢土屬和稀有土屬空間分布多樣性指數(shù)、地表水體空間分布面積指數(shù)及長度指數(shù)的粒度響應(yīng)類型,并研究指數(shù)間的相關(guān)關(guān)系及其穩(wěn)定性,旨在分析土壤與地表水體在空間分布格局形成上的相關(guān)性。結(jié)果表明:隨著空間粒度的增加,優(yōu)勢土屬和稀有土屬空間分布多樣性指數(shù)及地表水體空間分布面積指數(shù)的空間粒度響應(yīng)類型均屬于無響應(yīng)型,而地表水體空間分布長度指數(shù)的空間粒度響應(yīng)類型屬于無規(guī)律型;土壤和地表水體在空間分布上存在一定的關(guān)聯(lián)性,其中林州市水土資源的關(guān)聯(lián)性強(qiáng)且相關(guān)關(guān)系穩(wěn)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.
