Dynamic Monitoring and Analysis of Ecological Environment in the Coastal Tourist Destinations of Sanya City, Hainan

Abstract

Taking the Sanya Bay as the study area, based on the remote sensing images of Gaofen-2 in 2015, 2017, 2019 and 2020, this paper extracted 7 land use types of Sanya Bay. The main objectives of this paper includes: (1) Applying the theory of landscape ecology to calculate the landscape fragmentation and disturbance intensity in order to indicate the ecological changes in the study area; (2) Analysing the impact of landscape changes on the surroundings areas driven by the diversity of land use and perform the “Dynamic Monitoring and Analysis Technology for the Ecological Environment of Coastal Tourism Regions”. In which to monitor the dynamics of the ecological environment in the area of research. The results showed that the quality of the ecological environment in the study area changed dynamically with the construction of tourism sites: from year 2015 to 2017, due to a large number of construction, the ecological environment deteriorated to a certain extent; From 2017 to 2020, with the suspension of construction and environment restoration work, the quality of the ecological environment in the study area improved. Technology established in this paper provides a reference for the dynamic monitoring of the ecological environment in the coastal tourist area.
