基于生态敏感性的庐山区生态旅游用地策略

The strategy of tourism land in Lushan area based on evaluation of ecological sensitivity

脆弱的生态环境和突出的旅游资源禀赋是中部山地旅游地区的典型特征,该类地区旅游资源开发利用应建立在生态保护的基础之上。以典型旅游地区庐山区为例,基于自然生态和社会经济数据,选取坡度、高程、地形起伏度、河流水库、地质灾害易发性、自然保护区及文物保护单位、道路交通、土地利用类型8个因子作为研究区生态敏感性的评价指标,采用GIS技术与G1法相结合的方法,获取该区生态敏感性的空间分布图。研究结果表明,庐山区生态敏感性总体较高,极度敏感区、高度敏感区、中度敏感区、低度敏感区和不敏感区分别占到研究区总面积的11.91%、36.83%、11.29%、21.28%和18.69%。在此基础上,对不同的生态敏感性区域提出了相应的旅游功能区划与用地策略,以促进研究区生态旅游产业的进一步发展。

The fragile ecological environment and outstanding tourist resources are the characteristics of the central mountain tourism areas.The regional tourism resources development and utilization should be established on the basis of ecological protection.Taking Lushan Area,a typical mountain tourism city as an example,eight sensitive factors for eco-environment are selected based on the mountain ecological characteristics and status of human activities,such as slope,elevation,relief amplitude,reservoirs,susceptibility of geological hazards,nature reserves and historical sites and land use types.The use of GIS technology and G1 methods is helpful for us to obtain a comprehensive ecological sensitivity in spatial distribution of Lushan Area.The result shows that the ecological sensitivity of Lushan Area is generally higher,and the extremely sensitive area,the highly sensitive area,moderately sensitive area,low sensitive area and no sensitive area account for 11.91%,36.83%,11.29%,21.28%,and 18.69%of total area respectively.On this basis,corresponding tourism function zoning and land use strategy is proposed for the sensitivity to different ecological regions,so as to promote the further development of ecological tourism industry in the study area.
