【 摘 要 】

Songshan scenic area is a national-level scenic spot in Henan Province and has important economic and social value. The use of remote sensing technology can quickly evaluate the ecological environment and provide an important reference for the ecological environment management department of scenic spots. In this paper, GF-1 satellite imagery is mainly used to comprehensively consider the climate, topography, type of landforms and impact of human activities. The AHP method is used to evaluate the ecological environment of Songshan scenic area from 2013 to 2017. The evaluation results show that: in 2013, 2015, and 2017, the average values of the eco-environmental quality index were 78.9659, 81.2519, and 82.4581. The ecological environment status showed an improvement trend, and the reduction of land use intensity and the increase of vegetation coverage were the main factors for improving the ecological environment of the scenic spot. The areas with deteriorating ecological environment are mainly distributed in areas such as Shaolin Temple, Tallinn area and Songyang college.
