摘要:

我国西南喀斯特地区生态脆弱, 石漠化问题严重, 植被恢复/重建的难度极大。为此, 近年来开展了许多基础性研究, 以求为石漠化治理提供科技支撑。该文概略介绍了该地区喀斯特生境的特点, 回顾和评述了喀斯特生境中植物适应性、植物种群、植物群落和生态系统生态学方面取得的主要研究进展, 并结合石漠化综合治理的现状, 提出了喀斯特植物生态学研究的几点期望。

Abstract:

Karst region of Southwest China is ecologically very fragile. It has been suffering from severe rock-desertification and its vegetation has been damaging heavily. The restoration or reconstruction of the vegetation is extremely difficult. In recent years, a lot of pure and application-oriented basic researches have been performed in order to scientifically and technologically support the management of the rock-desertification. In this paper, we summarize habitat characteristics of the karst region and review the progress in ecological researches on plant adaptation, plant population, plant community and ecosystem in the region. In addition, as for current situation in management of the rock-desertification, we propose, particularly from angle of plant ecology, expectations for further researches in the region.
