- Abstract:
-
Soil erosion has been a main obstacle and influencing factor of sustainable use of farmland (especially slope cultivated land) in mountainous province. In the paper, the amount of soil loss under different slopes and cultivation methods in the whole province in 1996-2006 and the total amount of soil loss and soil erosion modulus of cultivated land at county level in Yunnan Province in 1996 and 2006 had been synthetically measured and calculated based on experiments of soil erosion in the past and the detailed investigation of land use and its change survey in 1996-2006 in Yunnan Province, combining Standards for Classification and Gradation of Soil Erosion formulated by the Ministry of Water Recourses of PRC in 1997. In addition, the authors had approached the basic characteristics of soil erosion on cultivated land, analyzed its harms to the sustainability of cultivated land use, and put forward the countermeasures of controlling soil erosion on cultivated land in Yunnan Province. This study has provided a basis for working out the future soil and water conservation planning and farmland protection planning as well as making rational policies of sustainable use for cultivated land in this province.
