| 摘 要： | 分别选取中国中、东部不同尺度典型样区为研究区域,将多样性理论与方法应用于水体空间分布多样性和土壤构成组分多样性评价中。计算了各研究区及其分区域内,以土属为基本单元的土壤构成组分多样性和2km×2km网格尺度下的水体空间分布多样性,并探索了两者之间的内在联系。研究结果表明:将多样性理论与研究方法应用于区域水资源的空间分布离散性评价具有可操作性;区域水体总面积变化与区域水体空间分布多样性变化之间具有一定的正相关关系,70%以上数据支持这一推断;区域水体比例与水体空间分布多样性之间并无绝对联系;水体和土壤研究数据均体现出分形特征及结构;区域土壤构成组分多样性与水体空间分布多样性之间存在负相关关系,大尺度区域下的相关系数R2约0.8。

| 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×2 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 R2 can be as high as 0.8 at a large spatial scale. |
