凤山河小流域岩溶地区石漠化综合治理

Integrated Management of Rocky Desertification in Fengshan River Small Watershed

凤山河小流域石漠化土地面积占总面积的31.6%,造成石漠化的主要原因有过牧、陡坡开荒、不合理耕种等.文中分别阐述了重度石漠化和潜在石漠化的治理对策以及综合治理模式.综合治理方案重点以恢复生态—拦水、引水一圈养建设为主,具体包括林业植被建设、小型水利水保措施、草地建设和草食畜牧业发展等措施,确定了治理率达90%以上,乔木林面积增加近500 hm2的治理目标,并对产生的效益和存在的问题作了进一步分析.

The rocky desertification land area in Fengshan river small watershed was 31.6% of the total area, the main reasons causing desertification were excessive grazing, steep slopes land reclamation, unreasonable farming etc. The paper expounds the severe rocky desertification and potential rocky desertification control countermeasures and comprehensive management models. The current comprehensive management project mainly focused on restoring ecology -dam, diversion-captive construction, including forestry vegetation construction, soil and water conservation measures in small water conservancy, grassland construction and the development of herbivorous livestock and other measures. Management goals of which the treatment rate by 90% , arbor forest area increased nearly 500hm2 were determined, and existing problems and future benefits also been analyzed.
