Ecological Restoration Strategy for Yuanmou Dry-hot Valley: Based on Immune Defensive Structure

摘要

It is necessary to take a more effective ecological restoration strategy in ecosystem-degraded regions typically represented by Yuanmou Dry-hot Valley, in order to reverse the trend of ecosystem services degradation. The four defensive hierarchical structures of natural immune system can resist the invasion of pathogenic microorganism and keep the organism healthy. The defensive hierarchical structure of immune system can be used for reference to build a strategy framework for sustainable ecological restoration, which is a trinity - the best way is to control or eliminate degradation factors, the lesser one is to cut off their contact with ecosystem, and the unwise but needed way is to take pertinence measures to control the degradation that has occurred. Accordingly, a strategy for restoring the Yuanmou Dry-hot Valley ecosystem is presented. The ecological restoration strategy based on defensive hierarchical structure has important guiding significance to restoration and control of other ecology degraded regions.
