基于GIS和RS的城市旅游生态环境适宜度评价研究——以梅州市梅江区为例

Study on Ecological Environment Suitability Evaluation of Urban tourism Basing on GIS and RS——A case study of Meijiang area in Meizhou City

旅游已成为当今许多城市的主要功能之一,而良好的城市生态环境是城市旅游赖以持续发展的基础。以城市旅游渐热的梅州市梅江区为例,利用GIS和RS相关技术,根据研究区的生态环境特征,运用DEM模型和TM影像,对研究区的坡度、坡向、相对高层和归一化指数(NDVI)等进行定量、定性相结合的分析,并结合层次分析法,对梅州市梅江区城市旅游开发的生态环境适宜度进行了评价。结果表明,梅江区大部分地区的生态环境适宜度较好,适宜旅游开发。在此结论的基础上,从选址、生态容量的确定到旅游产品的设计等方面进行了研究和探讨,这些研究和探讨对梅江区城市旅游开发具有积极的指导意义和参考价值。

Tourism has become one of the main functions in many cities and good ecological environment is the base for sustainable urban tourism.The research district is Meijiang area in Meizhou city.According to GIS,RS technologies and its ecological environment,we use DEM building and TM image to analyze the grade,the aspect of the slope,the relative elevation and the NDVI and combining AHP to evaluate Meijiang area＇s ecological environment suitability of urban tourism.The result is that the ecological environment suitability is good and it is suitable to develop tourism.At last,three points are presented about how to develop urban tourism in Meijiang area.They are choolsing right location,calculating fit ecological capacity and designing charming tourism products..
