The Establishment Of Information System Of Biomass And Npp In Greater Khingan Mountain Based On The"Map World "

In the context of "Digital Earth","digital forestry" gradually appear in people’s field of vision, its emergence for the country’s administrative departments at all levels and the macro decision-making of forestry company provides intuitive and convincing basis, is the important guarantee for sustainable forestry management."Digital Forestry" is the application of modern science and technology to improve forest management means, to achieve the premise of resource information, can effectively accelerate the forestry construction of the motherland. Under such a major premise, the study of forest resource information system is more and more important. Forest resource Information System is the model of forest resources and geographical Information System (Geographic Information System, GIS) formed by the combination of new effective professional Information System. GIS spatial analysis as a kind of can, data modeling and topology modeling, network modeling, the data can be stored and deal with all kinds of space information of high and new technology, has become a professional information system provides effective technical support." Map World " adopted now more popular B/S structure of network geographic information system (Web GIS), using the Internet HTTP protocol based on geographical spatial area location to have browse the requirements of users with different precision of Remote Sensing(Remote Sensing, RS) space image data. This research production system will be introduced to the "Map World " of Greater Khingan Mountain of Biomass and NPP information in information system, in order to "Map World " of the geographical spatial data, on the basis of the combination of Biomass and NPP simulation and estimation, achieve Greater Khingan Mountain of Biomass and NPP information professional information system, through the "Map World " to provide the use of remote sensing image data more vividly shows Greater Khingan Mountain of Biomass and NPP information, to a great extent, improve the work efficiency of the system, at the same time, the expression method of forest resource information also play a role for innovation, have certain reference significance.In view of the above requirements, this system mainly realize the following two major modules:Maps module:by the "Map World " API interface, the system of "Map World" foundation of geospatial data browse and query operations, such as the basis of the other is to realize the system function module;Thematic information browsing module:through regression of biomass model and BEPS model to calculate Greater Khingan Mountain of Biomass and NPP information, and the graphics output. Will be release, thematic map in the form of Web pages for users to browse the query, has reached the purpose of sharing resources.In the final part of the paper on the future work is prospected to Greater Khingan Mountain of Heilongjiang Province to achieve an effective combination of biomass and NPP thematic information and geographic information system for the masses, research departments and managers are provided with a more good way to query and browsing platform and forest resources information while in all walks of life with a wide range of practical value.
