Study On Decision Support System Of Forest Ecosystem Services Distributed Assessment

The forest is the major component part of the land ecosystem, as well as the cradle of human evolution. Forest plays a key role in the exchange of material and energy flow among the biological and non biological, play a central and leverage on the Earth’s ecological balance, to maintain the overall functionality of terrestrial ecosystems, and promote the economic, social and ecological construction coordinated development. With the increasing awareness of the ecological role of forest, forest ecosystem services assessment system is continuous improvement. At the same time, it becomes a huge project to construct digital Forest Ecosystem Research Station. With the increase in the number of Forest Ecosystem Research Station, and long-term positioning of the accumulation of observational data, we need mining effective, novel, potentially useful, and ultimately understandable information from the massive data, and provide these data visually presented to users.This study draws on forest ecosystem services assessment, and the results of the assessment of forest ecosystem services, according to5,6,7forest inventory data. Firstly, database and model base are constructed, and it is realize the seamless connection by using of ADO (Activex Data Objects) Data Access Technique, which can accessing database and get the data users want. Finally, the software "decision support system of forest ecosystem services assessment" is completed. It is proved to be avilability through system testing, program debugging, and the result shows the reliability of this software.
