摘要: |
为定量的评价土地整治前后产生的生态景观效应根据景观生态学相关理论,从景观效应和生态效应的角度,构建了4层级14个评价指标的土地整治生态景观效应评价体系。利用层次分析法确定指标权重,通过对比分析法划分指标等级及分值。将构建的评价指标体系运用于安徽省含山县某土地整治项目,对土地整治前后的生态景观效应进行评价。结果表明:该土地整治项目对区域的生态景观效应贡献率为13.86%,对区域的生态环境和景观功能起到了一定的改善作用,但存在较大的提升空间。 |

Abstract: |
In order to quantitatively evaluate landscape ecological effects before and after land consolidation,a land consolidation landscape ecological effects evaluation system,which contains four levels and fourteen indexes,is constructed.Comprehensively landscape and ecology effects are considered and relevant theories of landscape ecology are applied.AHP is used to determine index weight and apply comparative analysis method to determine indicators division level and scores.The evaluation system is applied to evaluate the landscape ecological effect of a land consolidation project,which is located at Hanshan Country,Anhui Province.The results show that contribution rate of comprehensive landscape ecological effects is 13.86% in the land consolidation project,which plays a certain improvement role in regional ecological environment and landscape functional although there is also a large room for improvement. |
