基于层次分析法和模糊数学的大连金石滩海岸整治修复工程效果评价

Evaluation of Coastal Rectification and Repairing Engineering Effect Based on AHP and Fuzzy Mathematics in the Jinshi Beach in Dalian

针对大连金石滩海岸整治修复工程效果定量评价的管理需求,本文采用层次分析法从自然环境效果、景观生态效果、沙滩资源效果和社会经济效果4个方面研究建立了海岸整治修复工程效果评价指标体系,并采用模糊数学方法构建了海岸整治修复工程效果模糊综合评价方法。大连金石滩海岸整治修复工程效果实证研究结果表明:本文研究构建的海岸整治修复工程效果模糊综合评价方法,涵盖内容全面,指标获取可行,评价结果明确,整体方法实用。大连金石滩海岸整治修复工程效果综合评价值为0.7755,综合效果为优秀,其中沙滩资源效果贡献率为30.73%,社会经济效果贡献率为30.59%,景观生态效果和自然环境效果贡献率分别为20.86%和17.82%。本文可为我国砂质海岸整治修复工程效果综合评价提供技术方法参考。

Aimed to propose a quantitative effect evaluation method for coastal rectification and repairing engineering management.This paper established effect evaluating index system for coastal rectification and repairing engineering from 4 aspects,which including natural environment,landscape ecology,sandy beaches resources and social-economic.The fuzzy comprehensive appraisal method was employed to create fuzzy comprehensive evaluation method for coastal rectification and repairing engineering effect.A case study of coastal rectifica-tion and repairing engineering in Jinshi beach in Dalian show:the evaluating index system and methods proposed by this paper are comprehensive and practical,the index acquisition is feasible and the result is clear.The effect of coastal rectification and repairing engineering in Jinshi beach in Dalin is excellent with the evaluating value 0.775 5,where the sandy beaches resources contribute for 30.73%,the socialeconomic contribute for 30.59%,and while the landscape ecology and natural environment account for 20.86% and 17.82%,respectively.
