Evaluation of Ecological Environment Quality of Tourism Industry in Guangxi Region Based on RS and GIS

For the regional tourism industry's ecological environment quality, this paper proposes the new concepts of Ecological GIS Entropy and GIS Entropy. Ecological GIS Entropy is used to measure the stability of the ecological environment of regional tourism industry, reflecting the extent to which different regional tourism industries affect the ecological environment. At the same time, the concepts of nodes, centers, and barriers are introduced to describe the sources and endpoints of GIS entropy in the ecological environment of the tourism industry, intuitively expressing the ecological stability of each region. In the experiment, we used remote sensing and GIS technology to extract land use changes and information on the ecological environment of the tourism industry, and obtained the result of decreased agricultural land and increased construction land in Guangxi Province.
