摘要 由于树草种选择、经营管理等方面存在的问题,在林草植被建设中出现了造林成活率低、保存率低和生态经济效益低的"三低"的问题。为了解决这些问题,促进市场经济条件下植被建设的健康发展,林草植被建设应该进行合理的规划和布局;使每块林地和草地达到植被建造的群落质量标准;提高不同利用目的森林植被之间的功能换算系数;使林草植被覆盖率达到一定的规模。 Vegetation construction is one of the main contents of ecological environment construction. There are three important problems of low surviving rate,low conservation rate and low ecological and economical benefits because of plant species selection and management. In order to solve these problems and promote the smoothly development of vegetation construction under market economy,some suggestions are proposed: firstly, reasonable arrangements including regional arrangement and vertical arrangement should be made before vegetation construction; sencondly, vegetation areas including every plot of forestland and grassland must achieve its quality criterion of community, functional conversion coefficient among different forest categories be increased, and appropriate cover rate of vegetation realized.
