利用GIS的分析功能和熵权理论,研究公路生态环境质量问题.采用压力—状态—响应概念框架模型和专家咨询相结合的方法确定公路生态环境评价指标,对各评价指标进行无量纲化处理后,利用熵理论计算评价指标的权重,并建立公路生态环境质量评价模型.在RS和GIS支持下,分析青海省A公路生态环境现状,借用MATLAB工具计算出各指标的熵值和熵权,并利用公路生态环境质量评价模型对该公路的生态环境质量进行定量分析.
Using the analysis function of GIS and entropy theory to study the highway ecological environment quality problems, the highway ecological environment evaluation index is determined by using the pressure-state-response conceptual framework model and the expert consultation method, and after the non-dimensional treatment of each evaluation index , Using entropy theory to calculate the weight of evaluation index and establishing highway ecological environment quality evaluation model.Under the support of RS and GIS, this paper analyzes the ecological status of highway A in Qinghai Province, and calculates the entropy and entropy of each index by using MATLAB The ecological environment quality of the highway is quantitatively analyzed using the model of highway ecological environment quality assessment.
