This paper adopt consistent coordinates, project, inosculate and integrate the wetland attribute information of the field investigation acquisition and the wetland space distribution information according to the remote sensing means acquisition. Based on these, we establish multi-dimension Chinese mire wetland database. The member of the item group implemented the contract request ,at the same time we completed the sort, coding, quantization of the mire wetland data, store in warehouse, integration etc. we complete the Chinese mire wetland database sets up the library job in the end; Establishment wetland remote sensing interpret tag; Established the related metadatabase; Create Chinese mire wetland website. The wetland database created to suffer the large wetland the worker welcome, the parts of wetlands data has been applied by lot of items.The paper primarily establish and integration the national mire wetland spatial database and metadatabase at the united norm and data expresses ,at the same time release and communion in the www.The concrete contents includes:(1) Create the Chinese mire wetland spatial database sort system of the in keeping with our country state of the nation, create the Chinese mire wetland coding norm of science.(2) Combined to literature and swamp wetland graph a Chinese mire, swamp of different scale, pick-up space attribute information of different type wetland.(3)Redacted the national mire wetland remote sensing interpret data of the different age, pick-ups and creates national mire spatial database with accurate coordinates in the 90's.(4) Make sure Chinese mire wetland metadata expresses form, create the metadatabase of the mire wetland spatial database.(5) Create the share strategy of the Chinese mire wetland data, provide the wetland data service and application demonstration, completed developments of the Chinese wetland website, created the Chinese wetland information subsystem.(6) The foundation on which the wetland data were tidied up, reunite the national mire wetland remote sensing interpret data of the different age, further arrive the mire wetland attribute data integration to Chinese mire in different age spatial database. By analyzing the characteristics of mire environmental data from diverse sources including remote sensing data, thematic maps, survey data and digital elevation model data, this paper aims to find out the relevant information extraction methods, put forward the principles and methods of mire classification and code which suit for the integration of environmental information of diverse sources, and get up the objects of the integration of environmental information of diverse sources, space coordinate transformation patterns and the organization methods of mire spatial and attribute data, which was formed after environmental information of diverse sources was integrated organically.(1) The mire environment analysis provided the possibility that is to pick-up more mire remote sensing information, the mire remote sensing interpret will can withdraw the internal boundary information of more mire.(2) The data integration of mire multi-dimension environment should consider the information source feature well. The remote sensing cans be fast, objective and reflect accurately the motion of the mire space distribution dynamic changes, the data gather of the integration should can withdraw the mire remote sensing interpret data which reflecting space boundary information. The mire thematic maps which vivid reflected the mire distribution state, because of the mire thematic maps update cycle which is long, its variety can't hold synchronization with the true condition. The survey information can provide microcosmic environment attribute information for the diverse environment data integration.(3) The target of the data integration of mire multi- dimension environment that is create different mire information have consistency and compared at space, time and attribute. the union make its organism incident. The data gather of the integration i...
