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。Scenic environment is the basis and prerequisite for the survival and development of scenic spots.The scientific evaluation of environmental quality of scenic spot provides an effective reference value for maintaining and improving the ecological environment of the scenic spot.Taking Bengbu Longzi Lake scenic area as an example, firstly, the paper introduces the general situation of study area, followed by the introduction of the principle and method of the scenic area ecological environment quality evaluation system, combined with the ecological environment characteristics of the Longzi Lake scenic area, Longzi Lake scenic area ecological environment quality evaluation system is established using the evaluation index and evaluation index of comprehensive index of 3 layer index frame model.Finally, the 2014 Landsat TM image and DEM data, extraction data of environmental factors, using geographic information system （G/S） of data for management and calculation, draw the evaluation unit of ecological environment quality comprehensive index （EQI）, and taking the opportunity of Bengbu Longzihu ecological environmental quality as- sessment basis to generate Longzi Lake scenic area ecological environment quality classification map.
