Zhalong Web Wetland Geographic Information System Design,

The wetland is one of the most important environment resources for human, and it is also important for supplying the water resource, meaning the flood, modulating the climate and protecting the variety of life forms. Currently, there is lack of effective instrument and scientific function for protecting wetland. It is very significant in both theory and realism to develop the research of wetland. With the rapid progress of Distributed Computing Technology, Object-Oriented Component Technology and the popularity of Internet, it comes a new technology WebGIS, which is a integration of WWW and GIS. WebGIS has now become one of the most important direction of GIS and has been used in extensive domain. Based on searching for and analyzing the wetland information, making use of the technique of GIS, internet, database, synthesizing current technological results and expert's experience, this research established Wetland Web Geographic Information System, to harmonize well and make use of kinds of wetland resources. The System can provide the fast and accurate information service with governments and researchers. The wetland GIS has three main parts: (1) Base information platform, provides the wetland information distribution on the internet; (2) Wetland information query platform, provides the easy and fast query of wetland information base on the internet; (3) WebGIS prototype system, provides the basic platform for studying the situation and environment of the ZhaLong wetland. This paper mainly discusses the principles and methods of the distributed WebGIS implementation, uses UML to make a detail analysis and design, and present the idea and scheme for this system. The research of the WebGIS prototype system will help to establish a dynamic monitoring system and provide a feasible scheme for wetland environment information.
