浅论水土保持生态建设中的生态自然修复

在任何自然环境下都会有相应的植物来生存 ,逐步形成植物群落 ,并由低级向高级逐步演替 ;环境对生长的植物进行适应性选择 ,适应该环境条件的植物能够繁衍、演替 ,不适应的就被淘汰 ,这是生态自然修复的理论基础。水土保持林草植被建设就是一个人工植物群落的形成过程 ,必须注意生态自然修复与人工治理相结合 ,包括以下几个步骤 :一是裸地成因及类型分析 ,二是植物种的选择 ,三是适时加大人工干预力度 ,促进进展演替。

Discussion on Ecological Natural Rehabilitation in Soil and Water Conservation Ecological Building

There would be some relevant plants alive under any natural environment, gradually forming plant community and conducting succession from junior to senior level step by step. Environment selects the growing plants for adaptability. The plant who can adapt itself to circumstances can increase gradually in number and continue succession or would be eliminated. This is the basic theory of ecological natural rehabilitation. Trees and grasses vegetation for soil and water conservation is the course of formed an artificial plant community. It should pay more attention to the combination of ecological natural rehabilitation and artificial management, including the following procedures: a) analysis on the cause of formation of naked lands and types, b) selection of plant types, c) strengthening artificial intervention timely and promoting development and succession.
