景观生态学与退化喀斯特生态系统恢复重建

Landscape Ecology and Restoration and Rehabilitation of Degraded Karst Ecosystem

本文分析了景观生态学中的景观格局与景观异质性理论、干扰理论、尺度理论、边缘效应理论与退化喀斯特生态系统恢复及重建的关系,其理论的应用能够指导退化喀斯特生态系统的恢复实践。同样,退化喀斯特生态系统的恢复与重建也为景观生态学的研究提供非常恰当的实验场。针对喀斯特退化景观提出一些恢复与重建模式以及今后重点研究方向。寓景观生态学思想于退化喀斯特生态系统恢复与重建过程是一种新的有效途径。

This paper analyzes the relations between landscape heterogeneity and pattern theory, distribution theory, scale and edge-effects theory which can guide the practice of restoration and rehabilitation of degraded karst ecosystem. Meanwhile, the ecological restoration and rehabilitation may assist landscape-level studies. Based on degraded landscape karst, some patterns of restoration and rehabilitation, as well as key research in the future, have been presented. Therefore, restoring and rehabilitating degraded karst ecosystem by using landscape ecology is a new effective way.
