摘要
基于DPSIR模型建立森林生态安全指标体系,采用熵值法和Lotka-Volterra共生模型分别计算指标权重与森林生态安全情况,并通过阻碍度模型测算森林生态安全的主要阻碍因素。结果表明:部分省份森林生态安全状态并不稳定,随时间变化而不断波动;森林生态安全主要受经济发展因素的制约;不同省份在经济条件、森林资源状况等方面存在较大差距,容易导致“环境倾销”现象的产生。基于此,提出构建新型核算体系、转变林业产业发展模式、加强区域内省份合作等建议。
Based on the DPSIR model,a forest ecological security index system is established.The entropy method and the Lotka-Volterra symbiosis model are used to calculate the index weight and forest ecological security,respectively.And the main obstacle factors of forest ecological security are calculated by obstacle degree model.It is found that the situation of forest ecological security in some provinces and cities is not stable and fluctuates with time.Forest ecological security is mainly restricted by economic development factors.Furthermore,there is a big gap among different provinces and cities in terms of economic conditions and forest resources,which will easily lead to the phenomenon of"environmental dumping".According to the results,some suggestions are put forward,such as building a new accounting system,changing the development mode of forestry industry,and strengthening regional provincial cooperation.
