Abstract: In order to better meet the needs of grassland ecological researches and assist in the development of local husbandry industry which is the economic foundation in Northern Tibet,the ecological information system for the grassland management in Northern Tibet,based on the powerful WebGIS and remote sensing technology,supported by advanced network and database technology,and centered with related ecological models,was designed and constructed in this study.The functions of the system include querying various spatial and attribute information,allowing users to make statistic charts as desired,providing thematic mapping such as grassland type and slope-aspect mapping etc.,analyzing grass-land types integrated with the slope,and supporting for decision making in management.All these functions are accessible by users through internet.During the procedure of system design,the four framework layers,the functional structure,and the database architecture of the system were designed.Except for the core functions,the system also consists of auxiliary functions such as map browsing,attribute querying,and system management.The design of database is comprised of the data analysis,gross structural design and coding design.Each module was developed based on relational database management system of SQL Server 2005 and WebGIS platform of ArcGIS Server 9.3,involving ajax technology,web service technology and flash technology.The performance testing of integrated modules shows that the system is reliable and practicable.
