GIS-Based Greenspace Management And Ecosystem Services Assessment

In this thesis, through preliminary investigation of the remote sensing information in Baosteel, then combined the survey data with the original data integration, Baosteel greenbelt information database was established. For the need of of Baosteel management and the purpose of practical application, Baosteel greenbelt management information system was built, based this platform, the ecosystem services evaluation function module was developed, which provided application interface for subsequent in-depth development of ecosystem services evaluation to ensure system scalability. Based on the principle of combining the practice and application, article drew conclusions as follows:(1) Baosteel greenspace information database was established. Through the analysis of greenspace remote sensing information and the collect relevant attribute data, three databases were built as follows:Baosteel basic geographic information database, Baosteel environmental and ecological background database, Baosteel greenspace information database. They provided a practical and reliable data for the greenspace management information development and ecosystem services evaluation module.(2) Baosteel greenbelt management information system was built. With the function of query, statistical analysis and geospatial analysis, the system can grasp the change of greenbelt resoueces so as to achieve the automatic management of greenbelt, deepen the analysis and provide the basis for other topics and decision support. System provided information on the ma nagement of green space, environmental information, biodiversity, ecosystem services and other information services, such as green space change management, development land planning and management, forest coverage rate inquiries, spatial location query, environmental information query, the query sample biodiversity, ecosystem services assessment, data editing, professional graphics and other functions.(3)The model of ecosystem services assessment was developed. With the theory of vegetation three dimensional green biomass (TGB) and the conversion model of TGB and value, combined with the appropriate valuation methods, system implemented the physical and value calculations of ecosystem service. Giving full play to the rapid development of the system, automation, intelligent advantage, the model of ecosystem services assessment was successfully embeded in the greenspace management information system.
