摘要
水土保持生态效益的计算与评价是水土保持科学研究的重要内容。根据水土保持项目实施后可能引起的区域生态要素变化的实际,探讨了土壤理化性质、水质、林草植被覆盖度和小气候变化的计算方法与评价方法。
Calculation and evaluation of ecological benefits of soil and water conservation are the important contents of scientific research of soil and water conservation. The paper approaches the methods of calculation and evaluation of the physical and chemical nature of soil, water quality, degree of vegetation of trees and grasses and changes of microclimate, based on the practice that regional ecological key elements might be changed after the implementation of soil and water conservation projects.
