Abstract: An evaluation indicator system of the ecotourism carrying capacity of the upper reaches of Lijiang River, a hotpot of ecotourism was constructed. The evaluation was carried out on the dimensions of ecological environment, social economic and tourism resources by means of GIS spatial analysis techniques and multi-level state space approach, on the basis of remote sensing data, GIS data, and socio-economic statistical data. After that, the space differential evaluation on the ecotourism carrying capacity of the upper reaches of Lijiang River was carried out. The results show that the overall ecological environment carrying capacity of this region is comparatively high. Specifically, the ecological carrying capacity in the western, northern and northeastern parts are relatively high. The overall social economic carrying capacity is lower, which presents relatively high in Guilin, moderate in Lingchuan County, and low in Xing’an County. The overall tourism resources carrying capacity is comparatively moderate in the region, while the northern Guilin, Xing’an County, the northern mountainous area, and the southern Lingchuan are higher. The area of ecotourism carrying capacity which achieves or is superior to the ideal state accounts is for only 29.28%. The spatial distribution of ecotourism carrying capacity is uneven, which means high in the southwest and northeast while low in the northern and southeastern parts. Finally, corresponding suggestions on the basis of evaluation are put forward, providing guidance for the development and protection of the upper reaches of Lijiang River region.

Key words: ecotourism carrying capacity, state space approach, promotion strategy, upper reaches of Lijiang River

摘要： 以生态旅游热点地区漓江上游为研究区, 构建生态旅游承载力评价的指标体系, 基于遥感影像、基础地理信息数据、社会经济统计数据等多种数据源, 借助GIS空间分析技术, 利用多维度状态空间方法, 从生态环境、经济社会、旅游资源3个维度对漓江上游进行生态旅游承载力空间分异评价。结果表明: 生态环境承载力总体较高, 西部、北部和东北部地区生态环境承载力强; 经济社会承载力总体较低, 但区县差异明显, 桂林市区较强, 灵川县中等, 兴安县较弱; 旅游资源承载力中等, 但桂林市区北部、兴安县城周边、北部山区和灵川南部较高。生态旅游承载力达到和优于理想状态的面积仅占29.28%, 空间分布不均衡, 西南部、东北部承载力较强, 北部、东南部承载力较弱。基于上述结果, 提出提升生态旅游承载力的实施途径, 为漓江上游生态旅游开发与生态系统管理提供借鉴。
