基于AHM模型和熵权法的旅游城市生态安全研究

Research On Ecological Security Of Tourist Cities Based On AHM Model And Entropy Weight Method

为提高旅游城市生态安全评估的准确性和可靠性,基于AHM模型和熵权法理论以云浮市为案例,构建了一个包含多个指标的旅游城市生态安全评价指标体系。首先,通过AHM模型对指标进行层次划分,得到了各个层次间的相对权重。然后,利用熵权法对各个指标的权重进行计算,最后综合得出云浮市的生态安全状况。结果表明,云浮市的生态安全整体得分良好,但在水资源利用和土地利用方面存在问题。提出优化生态环境、保护旅游资源、提升生态系统服务的建议,为云浮市的生态安全和可持续发展提供参考。

In order to improve the accuracy and reliability of ecological security evaluation in tourist cities,this paper constructs an ecological safety evaluation index system of multiple indicators based on AHM model and entropy weight method theory,and takes Yunfu city as a case.First,the indicators were hierarchically divided by the AHM model to obtain the relative weights between the various levels.Then,we can use the entropy weight method to calculate the weight of each index,and finally to synthesize the ecological security situation of Yunfu city.The results show that the overall ecological security score of Yunfu city is good,but there are problems in water resources use and land use.Suggestions on optimizing the ecological environment,protecting the tourism resources and improving the ecosystem services are put forward to provide reference and support for the ecological security and sustainable development of Yunfu City.
