The Analysis of Computer Models of Wetland Ecological Changes Based on GIS Technology

ABSTRACT

Wetlands are important to earth environment and ecosystems. With the rapid development of computer technology, establishing computer models of wetland analysis, especially models based on wetland monitoring, has become an important way to protect wetlands. Wetland monitoring needs data collection, entry, retrieval and analysis of a large number of representative wetlands. GIS technology application and wetland computer model can significantly improve the work efficiency. This paper provides a brief introduction of GIS, and an overview on wetland computer models based on GIS. This paper also studies the GIS application in data management model of wetland monitoring. Through the examples of GIS application in wetland monitoring analysis, the final GIS applications in wetland monitoring and computer models are put forward.
