湖南省旅游生态安全动态评价及障碍因素分析

Dynamic Evaluation and Obstacle Factors of Tourism Ecological Security in Hunan Province

旅游生态安全是实现旅游地高质量发展、推进生态文明建设的重要环节。文章基于DPSIR模型构建湖南省旅游生态安全评价指标体系,运用熵权TOPSIS法对湖南省2011—2020年旅游生态安全进行动态评价,采用ArcGIS软件分析其空间演变特征,同时借助障碍度模型,揭示影响旅游生态安全的障碍因子。研究表明:(1)研究期内,湖南省旅游生态安全系数呈“小幅度下降,大幅度上升”的波浪形演化趋势。空间上呈现出由西北和东南向中心逐渐变好的分布格局。(2)游客密度、生活垃圾无害化处理率、工业固体废物综合利用率、GDP增长率、旅游经济密度等是主要障碍因子。

Tourism ecological security is an important link to realize the high-quality development of tourism destinations and promote the construction of ecological civilization.In this paper,the tourism ecological security evaluation index system of Hunan Province was constructed based on DPSIR model,and the entropy weight TOPSIS method was used to dynamically evaluate the tourism ecological security of Hunan Province from 2011 to 2020.ArcGIS software was used to analyze its spatial evolution characteristics,and the obstacle degree model was used to reveal the obstacle factors affecting the tourism ecological security.The results show that:(1)During the study period,the tourism ecological security coefficient of Hunan Province shows a wavy evolution trend of“small decrease,large increase”.The spatial distribution pattern gradually improved from northwest and southeast to the center.(2)Tourist density,harmless disposal rate of household garbage,comprehensive utilization rate of industrial solid waste,GDP growth rate and tourism economic density are the main obstacles.
