摘要: 本文总结了20世纪90年代以来西南岩溶山地脆弱生态理论研究和生态重建实践方面的进展,从科学研究动态和生态环境退化以及恢复研究的现实需要两方面论述了西南岩溶山地石漠化与生态恢复研究的若干核心:植被过程研究、生态水文过程研究、景观过程研究、西南岩溶山地区域环境评估、预测与生态恢复研究。

Abstract: In this paper,the study on rock desertification and its restoration in southwest Karst mountain area was briefly reviewed.With reference to the trends in related scientific fields and pressing demand in restoring existing degraded lands,several key aspects,including vegetation processes,eco-hydrological processes,landscape processes and assessment of regional environmental state,prediction of rock desertification trends and exploration of restoration measures for the Karst mountain areas in southwest China were stated in order to discover mechanisms leading to rock desertification and to restore desertification lands.
