湖南省宁乡县巷子口—沩山荒漠化治理研究

巷子口—沩山地处我国南方红壤丘陵地区。由于长期过度砍伐和陡坡开垦等不合理人为活动的影响，加上降雨多且暴雨集中、丘陵地形和花岗岩母质的自然条件，这里由水蚀导致的荒漠化一度比较严重，１９８２年以来，采取封禁与造林相结合恢复植被、多途径解决农村能源问题、坡耕地退耕还林、广泛开展宣传、加强机构建设、落实政策、加强监督等措施，开展了荒漠化治理，取得了显著的生态和经济效益。

Study on the Control of Desertification in Xiangzikou Weishan, Ningxiang County, Hunan Province.

Xiangzikou Weishan is located in hilly red soil areas of Southern China. Water induced desertification there used to be quite serious as a result of integrated effects of long term human irrational activities such as over cutting, steep slope reclamation, etc. The natural conditions such as the plentiful of precipitation, the relatively concentrated occurrence of rainstorms, the hilly character of the area and the granitic bedrock are all the other causes. However, measures have been taken to control desertification since 1982 and remarkable ecological and economic benefits been achieved. The measures taken include: (1) combining closing hillside with afforestation to rehabilitate vegetation; (2) solving the problem of rural energy source shortage through multiple approaches; (3) changing slopeland for farming into for forestry; (4) extensive publicizing of combating desertification; (5) reinforcing institutional framework; (6) implementing of the concerned policies; (7) reinforcing the supervision to prevent desertification.
