云南省岩溶地区石漠化耕地现状及治理策略

云南省石漠化土地面积212.85万hm²,占岩溶土地面积的19.81%,其中石漠化耕地面积46.36万hm²,占石漠化土地面积的21.78%,石漠化耕地以轻度石漠化和中度石漠化土地为主，集中分布在人口稠密、经济欠发达地区。目前云南省石漠化治理存在着投资标准低，投入不足，治理需求大，成果巩固压力大，管理体制不顺，地方配套资金筹措困难等问题。藉此，提出遵循水土保持原则，因地制宜，改善农业条件，大力发展林禽林下经济模式，持续推进石漠化综合治理工程，节约集约用地，严把耕地红线关，降低石漠化区域耕地承载压力，遏制石漠化耕地发生等治理策略。

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 2.128 5 million hm², accounting for 19.81% of the karst land area. And the area of rocky desertification cultivated land is 463 600 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 treatment, 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 conservation, adapt to local conditions, improve agricultural conditions, vigorously develop the understory economy 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.
