| This is an important part of dynamic monitoring and evaluation of forest NPP geographic information system, a specific application of geographic information systems in forest NPP studies in. Inner Mongolia Forest NPP multi-scale spatial information system was studied,data acquisition from 2009 to 2010 of the major species NPP spatial data and supporting information related to GIS, processing and spatial databases. On this basis, multi-scale observations in Forest NPP spatial information systems planning and design, feasibility analysis, the specific needs of users, technical route, functional design, develop technology-depth were analyzed and discussed. through further learning and researching of Component technology and object-oriented software development technology, the function of concrete design and technology program were proposed. Finally, by the use of Visual Studio 2005 platform (integrated Visual Basic.NET Language) programming, provided by the secondary development of MAPGIS SDK6.7 Package (SDK), combined with ADO.NET database access technologies to carry on system development, including programming, commissioning and installation of production. This system realize the integration of space data and non-spatial data management and analysis, and forest NPP dynamic expression data visualization, multi-scale geographic data query based on spatial and non spatial data, provide a scientific basis for the timely and correct evaluation of forest conditions in Inner Mongolia and integrated ecosystem services. Finally, the main technical points of the research process, practical process, gaps and endeavors were summarized. |
