| 摘 要： | 根据模糊物元理论、合作博弈理论、并结合海明贴近度,提出了基于合作博弈权重的模糊物元后评价模型(FME-CGW)。将模型应用于黑河中游的生态影响后评价,评价结果表明:黑河流域治理项目对中游生态影响有较明显改善,评价等级为二级,与其他方法比较,结果基本一致,评价结果合理可靠。对工程项目生态影响后评价模型进行了初步探讨,以期为工程项目生态影响后评价研究提供一种实用可操作的定量后评价方法。

| Abstract: | Based on fuzzy matter-element theory,cooperative game theory and Hamming approach degree,the FME-CGW post-assessment model is proposed to assess the ecological impact of projects.The derived model is applied to the ecological impact post-evaluation in Heihe basin.The results show that the treatment project in Heihe basin is benefical to the ecological environment of the middle reach of Heihe River,and the ecologial environment of Heihe basin has been improved obviously.The results are reasonable and satisfactory by comparing to the other methods.This study is a preliminary discussion for the ecological impact post-evaluation model of projects,and could provide a practical and feasible method for ecological impact post-evaluation. |
