中文摘要：

分别选取河南省、江苏省省会城市郑州市和南京市,以及典型县域原阳县和如皋市,将土壤多样性理论与方法应用于土壤和土地利用关联性评价中,对上述不同级别行政区域的不同时期（1986-1988年、2000-2001年、2004-2006年）遥感数据进行土地利用分类,计算了土壤和土地利用类型的构成组分多样性以及3 km×3 km网格尺度下的空间分布多样性,提出并计算了各研究区典型土壤和土地利用之间的关联系数,以此评价了河南省和江苏省典型区域的土壤和土地利用构成及分布特征。研究结果表明,20世纪80年代至本世纪初,中东部之间和省会与县域之间的土地利用构成组分多样性变化和空间分布多样性变化具有明显区别;城镇建筑用地的空间分布离散性增加,南京市的增加量为0.135,略高于郑州市增量,而原阳县增加量为0.244,明显高于如皋市增量;典型土壤同城镇建筑用地、交通运输用地和工矿仓储用地之间的关联性均不断增加,南京市的上述关联系数增加值高于郑州市,两县域无明显区别。

英文摘要：

Two typical provincial capitals （Zhengzhou and Nanjing） and counties （Yuanyang and Rugao） in cen-tral （Henan Province） and east （Jiangsu Province） China were chosen respectively as the comparative cases for pedodiversity and land use diversity correlative analysis by borrowing the recently developed pedodiversity theory and methods in soil geography field. Land use classification was worked out using remote sensing imag-es in different times （1986-1988, 2000-2001, 2004-2006） for these studied areas before the calculation of the constituent diversity index and spatial distribution diversity index in 3 km × 3 km grid scale of each soil and land use pattern were conducted and a connection index was proposed to evaluate the relationship between soil and land use pattern of the studied provincial capitals and counties. Results show that during the years from 1980s to the beginning of this century, the changes of composition and spatial distribution pattern of central and east China had significant differences. The spatial distribution diversity of urban construction land of the case areas all increased in which Nanjing was a little bit higher than Zhengzhou, Yuanyang was significantly higher than Rugao. The connection index of typical soil and typical urban land uses （urban construction land, transportation land and industrial and mining area） all increased in this period during which Nanjing was high- er than Zhengzhou, Yuanyang was almost the same as Rugao. The introduction of diversity theory and methods to land resources evaluation was made in this study, by exploring the similarities and differences in the intrin- sic link and urbanization characteristics between soil and land use in central and east China in different times and space spans, this study figured that the urbanization of Jiangsu Province in east China took place earlier and developed faster than Henan Province in central China, and the urbanization process of Nanjing was the most obvious one.
