草原沙化治理工程生态效益快速评价体系研究

The Study on Ecological Benefit Evaluation Index System of Grassland Desertification Control Project

近年来,为了有效遏制草原沙漠化趋势,我国启动了一系列草原沙化治理工程来改善草原生态圈生态环境。如何对工程生态效益进行评价,建立一套科学、合理、具有可操作性的评价标准和指标体系,便成为当前迫切需要研究和解决的问题。根据我国草原沙化治理工程的实施背景和目的,结合草原沙化治理工程区的环境背景特征,遵循科学、实用及其简明等原则构建了草原沙化治理工程生态效益快速评价的指标体系,并用AHP法确定各指标的权重。

Recently, a series of desertification control project was started to improve the environment of grassland. How to evaluate the project and how to build a scientific evaluation system have become the problems should be solved quickly. Based on the background and purpose of desertification control project in grassland of China, combining environment character and social economy status in project area, the ecological benefit evaluation index system of grassland desertification control project was constructed, and the index weight was decided by AHP.
