恢复生态学理论对退化生态系统恢复的重要性

The Significance of Restoration Ecology Theory to the Restoration of Damaged Ecosystem

本文综述了恢复生态学的概念、研究对象、研究内容 ,并应用恢复生态学理论对几类退化生态系统 (湿地 ,喀斯特 ,采矿地 ,荒漠 )的恢复和重建进行论述。表明退化生态系统的恢复是以恢复生态学理论为依据的 ,恢复生态学理论对退化生态系统的恢复和重建起到积极的指导作用。恢复生态学的理论基础是生态演替 ,退化生态系统恢复的实质是群落演替。在此理论指导下 ,首先排除干扰 ,再建立生产者、消费者。

With the change of human's environment,more and more people are focusing on ecological restoration.This reason is just that,the existent crisis of human has been brought from damaged ecosystems ,which biodiversity and ecological function are depressed.Therefore restoration ecology has come into being in the surroundings.It is an applied branch of ecology to damaged ecosystem.The basic concepts,the contents and the object of restoration ecology were synthesized in this paper.At the same time,the restoration and reconstruction of several typical types of damaged ecosystem such as wetland,karst,mineral land,and desert were discussed.It shows that the restoration of damaged ecosystem bases on the theory of restoration ecology.This theory of restoration ecology positively guides the restoration and reconstruction of damaged ecosystem.The theoretic fouadation of vestoration ecology is juast ecological succession.The essence of restoration about damaged ecosystems in just the very ecological succession.Under this theory,damaged ecosystem can be restored by first getting rid of interferences,then setting up systems of producer,consumer,decomposer and minor habitats for eco-restoration to damaged ecosystem.
