Analysis of Land Use Change, Ecological Effect and Driving Force in Tourism Coastal Region——Taking Haitang District of Sanya City as an Example
Taking Haitang District of Sanya City as an example,ArcGIS and ENVI software were used to process remote sensing images from 2002 to 2022, explore the change trend of land use over the past 20 years,calculate per capita ecological footprint and ecological carrying ca-pacity, and analyze the ecological environmental effects generated by land use changes.The results showed that the land use status in Haitang District had undergone great changes, among which the most significant changes were cultivated land, forest land and construction land. The decrease of cultivated land and forest land was mainly for construction land.The rapid development of Haitang District in this period reflected the intensification of human activities on land use.The ecological effect of land use in Haitang District should not be optimistic.The ecological footprint and ecological carrying capacity supply in Haitang District developed in the opposite direction.The utilization of natural resources by population in Haitang District gradually approached the saturation range of ecological carrying capacity of natural ecosystem.
