Research on Application Status of 3S Technology in Wetland

Abstract

This paper analyzes the research status of 3S technology in China's wetlands. The research of 3S technology in wetland landscape pattern and driving force analysis is increasing day by day. Most of the research uses 3S technology to calculate the landscape index, and reveals the change rule of wetland landscape pattern characteristics with natural and human factors from the type scale and landscape scale. The use of 3S technology for wetland information extraction and dynamic monitoring research is gradually increasing. In most studies, wetland information was extracted according to different classification criteria, and spatio-temporal characteristics of wetland were analyzed based on area change, spatial distribution and shape change. With the development, planning and protection of wetland resources, the advantages of 3S technology will become more prominent.
