【摘要】：景区旅游经济的发展有赖于景区环境的不断维持与提高,科学合理的景区生态环境质量评价方法能够为景区生态质量提供很好的参考。该文以蚌埠龙子湖景区为例,首先介绍了研究区的概况,其次介绍了景区生态环境质量评价体系的原理和方法,利用评价指标-评价指数-综合指数的3层指标框架模型,建立了龙子湖景区的生态环境质量评价体系。最后,以蚌埠龙子湖2014年Landsat TM影像、DEM数据为数据源,基于RS和GIS技术,对数据进行自动计算处理,得出生态环境质量综合指数(EQI),依据EQI对生态环境质量进行分级与评价,然后根据不同区域的环境等级绘制龙子湖景区生态环境质量分级地图。
[Abstract]:The development of scenic area tourism economy depends on the continuous maintenance and improvement of scenic area environment. The scientific and reasonable evaluation method of scenic spot ecological environment quality can provide a good reference for scenic spot ecological quality.Taking Bengbu Longzi Lake Scenic area as an example, this paper first introduces the general situation of the study area, then introduces the principles and methods of the ecological environment quality evaluation system of the scenic area, and makes use of the three layer index frame model of the evaluation index-evaluation index-comprehensive index.The evaluation system of ecological environment quality of Longzi Lake scenic spot was established.Finally, based on the Landsat TM image Dem data of 2014 in Bengbu Longzi Lake, based on RS and GIS technology, the data were automatically calculated and processed, and the comprehensive index of ecological environment quality was obtained, and the ecological environment quality was classified and evaluated according to EQI.Then draw the ecological environmental quality classification map of Longzi Lake scenic area according to the environmental grade of different regions.
