Abstract :
Guangxi coastal wetlands, where is with the most intensive population and the most economically developed regions, bearing the enormous pressure of population growth, economic development and environmental change, is closely related with the progress of human society. 2010 TM satellite imagery and 1:50,000 topographic map are as the primary source of data in this article, "3S" technology (RS, GIS, GPS) as support, then spatial patterns of Guangxi coastal wetlands are obtained. The current situation and characteristics of ecological environment and ecosystem service functions of Guangxi coastal wetlands are analyzed, and base on the ecological security pressure, ecological security status and ecological safety response, the weight of evaluation index is determined with the Analytic Hierarchy Process (AHP), evaluate ecological security situation in Guangxi coastal wetlands, and ultimately the Guangxi coastal wetland ecosystem restoration and protection measures are put forward.
