喀斯特地区石漠化生态治理与可持续发展

Ecological Control of Rocky Desertification in Karst Area and Its Sustainable Development

喀斯特地貌石漠化和黄土、荒漠、冻土等并称为中国西部的四大生态环境脆弱带,是限制可持续发展的一个十分重要的因素。随着西部大开发的推进,生态环境问题已经引起高度重视。由于我国石漠化分布广,加之人为因素的影响,植被遭受破坏,水土流失严重,土地石漠化愈演愈烈。通过对喀斯特地区石漠化现状及危害的分析,提出以可持续发展为目标,以生态学、生态经济学原理为指导,通过生态治理措施,分别不同地区、不同退化程度进行分类治理,为改善喀斯特石漠化的生态环境和实现可持续发展提供参考。

Rocky desertification, loess, desert and frozen soil are the fragile ecological area of west China, which astricted the sustainable development of the area. With the program of west development, eco - environment has been paid more attention to. Due to the wide distribution of desertification and mankind disturbance, vegetations are being destroyed gradually, soil corroded acutely, desertification worsened rapidly. In this paper, the actual situation of the desertification and its damages is analyzed. Aiming at sustainable development under the guidance of the principles of ecology and eco - economics, some ecological management measures are put forward,for the control of different - degree desertification in different areas. This will be available to the re -vegetation and the protection of the ecoenvironment in these areas, and there by to sustainable development.
