4 Conclusions
ArcGIS Server, ArcSDE, and GeoDatabase technology are used to design and implement the wetland resource WebGIS. Functions of the system include wetland resource data management, query, analysis, sharing, science and education, and remote management. The system can facilitate the management and utilization of wetland resource and provide aided decision support for administrators. The system makes wetland resource management and utilization more systematic, scientific and integrated. Through the study of wetland resource WebGIS, some conclusions are draw as following: (1) WebGIS technology can promote sharing of wetland resource data; provide more accurate, vivid, and abundant wetland resource data for the public, administrators, and researchers through web page; and provide real time and precise information support for all kinds of users. (2) Updating and maintaining wetland resource data using WebGIS is more fast and convenient; all kinds of users can upload, download, update, and maintain wetland resource data by Internet at all times and places in the world. (3) WebGIS can be used to propagate wetland knowledge in efficient, visual, and global ways, and raise wetland ecological tourism awareness. (4) Constructing Wetland resource information system with ArcGIS Server has the features of generality, applicability, shorter development cycle, stability, and reliability. Using computer technology, GIS technology, and network technology, etc. in wetland resource management can effectively enhance the management level and efficiency. This should be introduced to other wetland nature reserves to use. Although the system has the above advantages, there are some disadvantages about it, such as poor spatial analysis, slow remote access speed for spatial data, map data, and streaming media data limited by network bandwidth, poor visualization function. In the future work, the study further aims to strengthen the spatial analysis function, visualization function, and web streaming media play function, etc. in wetland resource WebGIS.
