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.
