摘要
基于川藏铁路青藏高原地区环境脆弱,且铁路沿线生态空间修复在环境保护和水土保持中的重要作用,从土壤生态修复、植被修复、水环境修复、自然资源修复、大气环境修复以及工程措施修复等6个方面建立综合评价指标体系。利用博弈论(GT)将IGAHP法和向量夹角余弦法加权组合,确定各评价指标的综合权重;运用二维云模型从效果和经济性2方面对铁路沿线生态空间修复状况进行综合评价,借助MATLAB绘制二维云图,并计算贴近度,进一步确定评价结果。选取川藏铁路拉林段作为评价对象,对其沿线受损生态空间的修复状况进行综合评价,验证了该模型的适用性和有效性。
Based on the fragile environment of the Qinghai-Tibet Plateau of the Sichuan-Tibet Railway and the important role of ecological space restoration along the railway in environmental protection and soil and water conservation,a comprehensive evaluation index system was established from six aspects,which were soil ecological restoration,vegetation restoration,water environment restoration,natural resource restoration,atmospheric environment restoration,and engineering measures restoration.Then the game theory(GT)was used to weight the IGAHP method and the vector angle cosine method to determine the comprehensive weight of each evaluation index.The two-dimensional cloud model was used to comprehensively evaluate the ecological space restoration along the railway from both effects and economy.The MATLAB was used to draw a two-dimensional cloud map and calculate the closeness to further determine the evaluation results.Finally,the La-Lin section of the Sichuan-Tibet Railway was selected as the evaluation object,and the restoration status of the damaged ecological space along the line was comprehensively evaluated,which verified the applicability and effectiveness of the model.
