Current Situation and Control Strategies of Rocky Desertification Cultivated Land in Karst Areas of Yunnan Province
The area of rocky desertification land in Yunnan Province is 2.1285 million hm2,accounting for 19.81%of the karst land area.And the area of rocky desertification cultivated land is 463600 hm2,accounting for 21.78%of the rocky desertification land area.The rocky desertification cultivated land is mainly composed of mild and moderate rocky desertification land,concentrated in densely populated and economically underdeveloped areas.At present,the treatment of rocky desertification in Yunnan Province exists some problems,such as low investment standards,insufficient investment,high demand for treat-ment,pressure to consolidate achievements,unfavorable management system,and difficulties in raising local supporting funds.Therefore,this paper proposed to follow the principles of soil and water conserva-tion,adapt to local conditions,improve agricultural conditions,vigorously develop the understory econo-my of forests and poultry,promote the comprehensive management project of rocky desertification,save and intensively use land,strictly control the red line of cultivated land,reduce the carrying pressure of cultivated land in rocky desertification areas,and curb the occurrence of rocky desertification.
