Study On Integration For Integrated Monitoring Of Forest And Wetlands Resources

With the times and technology development, forest and wetlands resources monitoring has been a gradual transition to more resources, multi-function monitoring, and further development to adapt to sustainable development of forestry and forest resources, and Integrated monitoring of wetlands. Forest and wetlands resources Integrated monitoring data indicate the development trend of wetlands resource quantity, quality and that of other related ecosystems; furthermore, these data can be given an effective way to study on forest, wetlands and variations of ecological conditions. The results of Integrated monitoring are important bases of the development of forestry science, and give some basic information for sustainable forestry development, evaluation of key forestry ecological construction projects and forest management.The resultant effect was hard to exert because of the relatively independence of monitoring of forest, wetlands resources and other ecosystems each other; in addition, the results of forestry development and ecological variation could not be evaluated objectively by existing monitoring data, and development trend could not be forecasted. Compared to other nations that used more advanced monitoring technologies, in our country, more technologies were still backward, for example, organization, management and veracity of monitoring data and so on. According to the analysis of the basic meanings of forest and wetlands resources, and then studied on Integrated monitoring system our country and abroad, and summarized the current situations and key problems of forest and wetlands resource monitoring technology of China. The trains of thought of integration of forest and wetland resources Integrated monitoring were discussed in theory, technology, content and method level, and the key elements of Integrated construction were put forward; and moreover, the integration of forest and wetland resources Integrated monitoring based on standard specification and construction was conceived. Based on 3S, PDA, Network, Database and other technologies, built the platform of integration of forest and wetland resources Integrated monitoring, and furthermore, integrated with forest resources, wetlands, forest disaster, and key forestry projects of various monitoring and evaluation of technology and special systems, and achieve forest resources, wetlands, forest disasters, monitoring of key forestry projects, data, models of unified storage, management and system integrated running sequentially. This study involves the following:(1) According to the analysis of existing forestry and related standards, building forest and wetlands resources Integrated monitoring integrated standards, as forest and wetland resources Integrated integration standard specification, including metadata standards, data integration standards, systems integration standards and integrated services standards.(2) Data integration supported the database of forest and wetland resources Integrated monitoring which is the basis of information systems. Our study used spatial data engine technology combined with object-relational database to establish an unified data model and an unified database management system, to break out inherent management and boundaries of forest and wetland resources data, to achieve multi-source forest and wetland resources data integration, as the foundation of forests and wetlands for sharing. Data organization is organized by application subject, divided the public data and various special data, public data can be shared for all business sectors.(3) Technology integration is the base of system integration of forest resources. In the Integrated monitoring of forest resources of technology integration, the most important part is integration of GIS, GPS, RS, 3S technology and its integration are the key to realization of digital forestry. Applied 3S, PDA, database, integration of visual modeling techniques to forest and wetland resources monitoring, management, evaluation and other aspects, and formed integrated monitoring system.(4) Function integration is the goal and soul of system integration. According to analysis the function of the system of forestry, extracting public functions, models and algorithms from the professional systems. On the basic of analysis of different kinds of integration methods, in support of modern software development techniques, proposed component-based technology integration ideas: geographic information system functions used Beijing Chaotu company's library and developed, business-related professional feature in accordance with certain specifications into the system by plug-in manner, overcome the disadvantages such as openness, scalability, maintainability, recombination capacity of old system.(5) Faced to application subject of multiple targets monitoring technology and integrated service technology, and used Web services and visualization methods for forest resources, wetlands, forests disaster and monitoring and evaluation of main forestry projects to supply sharing and analysis services.
