【摘要】：生态环境较脆弱和自然旅游资源较丰富是山地旅游城市的重要特点。在旅游开发中,山地旅游城市的生态敏感性对旅游用地的规模和方式产生影响,旅游用地策略应建立在生态敏感性评价的基础上。以典型山地旅游城市张家界市为例,基于山地生态特征和人为活动状况,选取高程、坡度、植被覆盖、水域和地质灾害易发性等5个因子作为生态敏感性的评价指标,运用遥感和GIS技术,采用因子加权叠加法,得到张家界市域综合生态敏感性空间分布图。结果表明,张家界市域生态敏感性总体较高,区域差异明显,高度敏感区、中度敏感区、低度敏感区和不敏感区面积比重分别为研究区总面积的20.93%、67.16%、11.57%和0.34%。在对生态敏感性分析的基础上,根据不同生态敏感区的实际情况提出了相应的旅游用地措施,为张家界市生态环境保护和建成国际风景旅游城市提供理论依据和实践路径。
[Abstract]:The fragile ecological environment and rich natural tourism resources are the important characteristics of mountain tourism cities. In the tourism development, the ecological sensitivity of mountain tourism cities has an impact on the scale and mode of tourism land. The strategy of tourism land use should be established on the basis of ecological sensitivity evaluation. Taking Zhangjiajie city, a typical mountainous tourism city, as an example, the elevation, slope and vegetation cover should be selected based on the ecological characteristics of mountainous areas and the condition of human activities. Five factors, such as water area and geological hazard susceptibility, were used as the evaluation index of ecological sensitivity. Using remote sensing and GIS technology, the factor weighted superposition method was used. The spatial distribution map of comprehensive ecological sensitivity of Zhangjiajie city was obtained. The results showed that the ecological sensitivity of Zhangjiajie city was high, the regional difference was obvious, the high sensitive area and the moderate sensitive area. The specific gravity of low sensitive area and insensitive area were 20.933% and 0.34% of the total area of the study area, respectively, and 11.57% and 0.34% of the total area of the study area, respectively, on the basis of ecological sensitivity analysis. According to the actual situation of different ecological sensitive areas, this paper puts forward the corresponding measures of tourism land, which provides the theoretical basis and practical path for the protection of ecological environment and the establishment of international scenic tourism city in Zhangjiajie city.

【正文快照】： 生态敏感性是指生态系统在不损失或不降低环境质量的前提下,生态因子对人类活动或自然环境变化的适应能力,是表征区域生态环境问题发生难易程度和概率大小的度量[1]。一般而言,区域生态敏感性越高,生态系统就越容易受损,也越容易产生生态环境问题。位于我国中西结合部的山区城
