- Abstract:
-
Based on the farmland grade results in Yunnan Province, we analyzed the characteristics of spatial distribution of cultivated land use to serve the development of agriculture industrialization, improve soil and use land from the view of zonal soil by combining statistics and overlay analysis. The results showed that:(1) utilization grades of cultivated land within lateritic red soil, latosol soil and mountain and upland red soil widely were identified as from grade 2 to grade 5, and the idenitfied gradation which was above grade 7 accounted for a little proportion. The grades of cultivated land within yellow brown and brown soil appeared from 1 to 6; (2) the average utilization grade of cultivated land within different zonal soil types decreased with the increase of elevation, and grades of yellow brown and brown were lower than the other’s at the same elevation; (3) with the increase of latitude, the average utilization grade of cultivated land belonging to latosol and lateritic red soil types increased while the another reduced. This research results could support the work of improving soil, land consolidation and developing agriculture industrialization.
