多目标决策灰色关联投影法在生态脆弱性评价中的应用

Application of Multi-criteria Decision Grey Relation Projection Method in Ecological Vulnerability Evaluation

【目的】为生态脆弱性评价提供了一个可行的方法,同时应用生态脆弱性分区结果可为后续的生态环境恢复重建工作、制定综合治理策略及区域可持续发展规划提供依据。【方法】以典型生态脆弱区贵州省为研究区,根据导致该省生态环境脆弱的自然-结果表现因素,构建科学客观的评价指标体系,运用多目标决策灰色关联投影法进行生态脆弱性分析评价。【结果】结果显示,贵州省生态脆弱性从小到大为:贵阳市>黔西南布依族苗族自治州>六盘水市>铜仁市>黔东南苗族侗族自治州>安顺市>黔南布依族苗族自治州>遵义市>毕节市。【结论】多目标决策灰色关联投影法在生态脆弱性评价中的运用具有可行性,本研究评价结果与前人研究结果相对一致,可用于生态环境建设参考。

[Objective] Our aim is to provide a feasible way to evaluate ecological vulnerability. Meanwhile, evaluation results can be useful for subsequent restoration and reconstruction of eco- environment and for scientific basis of comprehensive strategies and regional sustainable develop- ment. [Method] Guizhou province, one of the most typical ecological vulnerable area, is study target in this study, according to the natural factors resulting in ecological vulnerability of the Guizhou, a scientific and objective evaluation index was set up to analyze and evaluate the ecologi- cal vulnerability by using the method of multi-criteria decision grey relation projection. [Results] Our results indicated that the order of ecological vulnerability in Guizhou was Guiyang〉Bouyei- Miao Autonomous prefecture of Southwest Guizhou〉Liupanshui〉Tongren〉Miao-Dong Autono- mous prefecture of Southeast Guizhou）Anshun）Bouyei-Miao Autonomous prefecture of South Guizhou〉Zunyi）Bijie. [Conclusion] It is reliable to apply the method of multi-criteria decision grey relation projection in ecological vulnerability evaluation. Meanwhile, similar to previous re- search, our results can also be used for reference of ecological environment construction.
