Abstract

Abstract: Ecological evaluation is of great significance for the scientific and effective management and sustainable development of nature reserves. Based on Landsat images with a spatial resolution of 30 meters and GLASS data with a time resolution of 8 days, this paper uses ecological quality index (EQI), which is calculated as weighted ecological function index, ecological stability index, and ecological stress index, to evaluate the ecological environment quality of Fangcheng Golden Camellia National Nature Reserve in Guangxi from 2005 to 2019. The results show that the overall ecological quality of the reserve is good. The quality of the ecological environment is continuously improving during 2005-2019. Areas with poor and low ecological grades are mainly distributed around the protected area, and their proportion has increased year by year since 2014. This is closely related to the human disturbance activities of the surrounding residents.

Key words: ecological quality index, Golden Camellia National Nature Reserve, ecological environment, ecological function index, ecological stability index, ecological stress index
