西南喀斯特地区石漠化问题研究综述

Review of Research on Rock Desertification in the Southwest Karst Area

喀斯特地区石漠化是在脆弱的生态地质背景基础上叠加了人类活动而出现的。西南地区的石漠化面积现仍约以2 500 km2/a的速度进一步扩大。石漠化的生态治理工作的目的就是要在人为作用的干扰下,使这种逆向演替转变为顺向演替。石漠化治理思路设计的科学性、战略性、可行性决定了最后石漠化的治理结果。在喀斯特石漠化的治理中,要根据不同岩溶环境类型区及石漠化发育的不同程度和不同山地的立地条件,针对其特点,选择多种途径,运用恰当的恢复技术,制定出具体的开发治理措施,实行规模治理,以提高资源利用率,促进石漠化生态环境的综合治理。

Desertitfication in Karst area that the fragile ecological geological background is superimposed the human activities appears, is still in further expansion by about a 2 500 km^2/a. The purpose of desertification of the ecological management is to switch reverse - changing succession to the succession in the role of human interference. The scientific, strategic and feasibility of the design - ideas of desertification control is related to the final results. In the desertification governance according to the different types of Karat environment, different development levels of desertification, and different mountain site conditions, select a number of ways, use the appropriate restoration technology, work out concrete development and control measures, and implement the scale of governance to improve the rate of resources utilization and promote the comprehensive improvement of the ecological environment.
