多目标决策灰色关联投影法在生态脆弱性评价中的应用

【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。

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

【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 development.【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 ecological 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 Autonomous 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 research,our results can also be used for reference of ecological environment construction.
