摘要

以重庆岩溶地区为例，探讨岩溶地区土壤类型的多样性与不同土壤类型上土地利用方式的多样性。结果表明重庆市岩溶区黄壤、石灰土和黄棕壤是本区主要土壤类型，土壤景观的多样化和空间异质化程度不高，但各类景观分布比例不均匀，土壤景观嵌块体呈现出复杂的几何形状。除了山地草甸土以林地和草地、棕壤以林地为主要景观外，另外的9种土壤类型上都是以耕地和林地为主要的景观，农、林用地在景观空间格局的结构和功能中起主导作用。由于各类土壤性质和分布特点的不同，耕地和林地在各类土壤上的分配比例存在着明显的差异，以及人类活动使得耕地的嵌块体数急剧增多和居民工矿用地、林地、未利用地的嵌块体数目增加。

Abstract

It discusses the pedodiversity and land use pattern diversity of different soil types based on a case study of Chongqing karst area. The result shows that yellow soil

limestone soil and yellow-brown soil are the major soil types in Chongqing karst area

the landscape diversity and spacial heterogeneity of different soil types are low

but the distribution of landscapes is uneven

the landscape mosaic patches present complicated geometry shape. The landscape of mountain meadow soil is dominated by forestland and grassland

the landscape of brown soil is dominated by forestland

the land use of agriculture and forestry plain a leading role in the other 9 kinds soil landscape. Owing to the difference of soil properties and soil distribution

there is a obvious difference of plantation and woodland distribution proportion in different soil types. The human activities make the number of plantation mosaic patch increase rapidly

and make the numbers of residential and industry-mine land

woodland and unused land increase also.
