| Abstract: | Wetland is a special ecosystem between land and water. It can provide massive foods, raw material, water resources and habitat for human being, animals and plants. Wetlands are so important that wetlands' development, management and protection have become the focus of public attention. The technology of Remote Sensing (RS), Navigation Satellite Timing And Ranging Global Position System (GPS) and Geographic Information System(GIS) can support to carry out wetlands' studies and to establish platform of wetland management. So 3S(RS, GPS and GIS) technology has been applied widely to many aspects of wetland researches, such as investigation of wetland resources, dynamic monitoring of change of wetland landscape pattern and resources and so on. Here we mainly give the summary of application of 3S technology to wetland researches on six aspects. First, during the process of survey of wetland resources, the data of various kinds of wetland resources can be obtained from RS images. By the image data, the around environment and interior structure of wetlands could be understanding. The high accuracy localization ability of GPS may provide RS and GIS accurate wetland localization data. GIS technology with its formidable spatial analysis and data management functions carries on the spatial analysis and attribute data management for RS and the GPS data. Second, 3S technology is used to monitor dynamic changes of wetlands, including images processing, field validation and amendment of wetland thematic map. Third, 3S technology has rapidly become important technology for analysis of landscape change of wetland since 1980s, which enormously promoted the development of landscape quantitative investigation provide data base for each kind of landscape pattern. The steps of analysis of wetland landscape are to choose the RS images as the basic data; then, to use RS soft wares to do classification and gain each kind of landscape thematic map; next, to calculate each landscapes' parameter, area, perimeter and all landscapes amounts with GIS; finally, according to the landscape ecology principle, to calculate each kind of landscape index based on these foundations. Fourth, remote sensing image has reality, dynamic and accurate characteristics, which can provide the huge information for wetland mapping. At the same time, GPS can provide the accurate localization of wetlands and has formidable mapping function of GIS can do wetland map. 3S technology can meet all kind of thematic mapping requirements. Fifth, 3S technology can support management of wetland resources. Sixth, using the 3S technology also can estimate the biology resources of wetlands and carry on the biodiversity analysis and evaluation. 3S technology can investigate and study the wild animal habitat of wetlands. Using the vegetation spectrum model can do the inversion of wetland vegetation biophysics parameter and so on. |
