中国中、东部典型样区土壤和水体多样性关联分析
Correlative analysis of pedodiversity and spatial distribution of water body diversity at different scales in Central and East China
摘要
Abstract
Five study areas with different sizes from Central and East China are selected for a correlative analysis between the diversities of soil constituents and water body spatial distributions. Remote sensing data for 2000 -2001 and 2004 -2006 are used to classify the land cover types and the land-use maps in the study areas. The information is further processed to produce the pedodiversity indices and the diversity indices of water body spatial distributions at a resolution of 2 km x2 km. The correlative analysis is then conducted to explore the inherence relationship between the two index types. Results show that it is maneuverable and practical to apply the diversity theories and approaches to studying the spatial discreteness in water resources distributions. The soil type numbers can be related to the area sizes in study areas. There is a positive relationship between the variations of area sizes and spatial distributions of water body diversity. The relationship is supported by over 70% data. However, there is no absolute linkage between the proportion of water and the spatial distribution of water body diversity. The fractal characteristics and structures are found in both soil and water data samples. There is a negative relationship between the diversities of soil constituents and water body spatial distributions. The correlation coefficient R can be as high as 0.8 at a large spatial scale.关键词
