Abstract: Camping is an important way to develop ecotourism in China’s nature reserve. The scientific and reasonable site selection for camping is an important prerequisite for the healthy development of camping and the sustainable utilization of natural resources. Taking the North Luoxiao National Forest Park of Hunan province as the research object, the spatial suitability of the tent camp site as the research content, the evaluation index system was constructed from 4 project levels including natural environment, landscape conditions, security conditions and infrastructure and 15 index levels. Delphi and AHP methods were used to determine index weights. The spatial distribution map of tent camping environmental suitability in the North Luoxiao National Forest Park was drawn using the ArcGIS10.2 spatial information processing technology based on the sensing images and survey data on site. The results showed that the areas with very high and high suitability for tent camping only accounted for only 9.61% of the park area which have complete infrastructure, good safety conditions and superior landscape conditions. The areas with general suitability accounted for 61.92%, which have poor natural environmental conditions and infrastructure, good safety conditions and landscape conditions. The areas with low suitability accounted for 28.42%, which have poor safety conditions, poor safety conditions, and infrastructure.and are mainly The extremely low-suitability areas are rarely distributed, accounting for 0.05%, which have poor natural environment, safety conditions, high threat of mountain torrents, general infrastructure. The method we conducted in our paper can quickly and quantitatively evaluate the space suitability of tent camping in mountain scenic area, which is helpful to the strict protection and scientific and reasonable utilization of forest landscape resources in the study area. The method is quick and accurate and has strong operability and promotion value, and can also be applied to the site selection and land evaluation of tent camping projects in other mountain natural reserve.
