Cooperative Information System For Forest And Greening Resources Monitoring Of Metropolitan

The metropolis is the result of social and economic development to a certain stage. The number of metropolises has increased enormously in China in recent decades. At the same time, the scale of them has also been further expanded. Forests and greening as natural infrastructure to preserve the ecological environment is more important to metropolis, which is characterized by great denseness in population, concentration of industry, traffic congestion and pollution serious damage the environment, than ever. Therefore, manage forests and greening becomes important security measures to the economic and social development of metropolis. Accordingly, attention is given to the forests and land resources to monitoring, which has the target of gathering forests and greening resources information.Based on many documents about forest and greening resources monitoring, study on cooperative information system and science of ecology construction in urban, combining the research results of forest and greening resources management and the theories of forest management, greening planning, ecology and information science, the monitoring information cooperation of forest and greening resouces was studied and discussed on the sides of theory, technology and application by the method of comparison and synthesis. A metropolitan forest and greening resources monitoring information cooperation architecture was put forward and was proved in Beijing.There are four results as following are made in the dissertation:1)The conception of metropolitan forest and greening resources monitoring information cooperation was brought forward, viz, cooperating the two objects of forest resources monitoring and greening resources monitoring in a metropolis by means of information integration and founding cooperative mechanism to finish resources monitoring tasks together. It was considered that metropolitan forest and greening resources monitoring information cooperation can be studied in the aspects of index system, subdivision,survey, updating and application services.2) Based on the reorganized results of forest resources monitoring and greening resources monitoring, the problems about business cooperation, departments and workers cooperation and data cooperation in monitoring businiss was analyzed. The cooperative relations and cooperative problems were also elaborated from the five aspects.3) Information cooperative architecture of metropolitan forest and greening resources monitoring was constructed. It is composed by cooperative elements, cooperative mechanism, and cooperative implement. Cooperative elements are basic elements of realizing of information cooperative. It included data, business, and department and so on. Cooperative mechanism is composed by sharing mechanism, restraint mechanism, process cooperative, role cooperative and assessment system. Based on all of these, cooperative models were constructed in five key points in metropolitan forest and greening resources monitoring. There are index system, management subdivision, survey, updating and application service.4) Users and functions of information cooperative system of metropolitan forest and greening resources monitoring was analyzed. The architecture of the system was put forward based SOA. The system was divided to five levels, which were client application, application supported, service, service supported and supporting infrastructure. The dissertion concretly analyzed key techniques, including role-based access control, the technique of integrity of subdivision data, and smart client. A system was constructed in Beijing by using the techniques said above.The main contribution of this research:1) This dissertation make systematic research on cooperation monitoring information by taking metropolitan forest and greening resources as the research objects for the first time. Up to March 2010, the result of Literature Retrieval shows that the research on information cooperative system of metropolitan forest and greening resources monitoring is the first example.2) Connotation of information cooperative of metropolitan forest and greening resources monitoring was analyzed in cooperative purpose, cooperative objects, cooperative content and cooperative characteristics. Theoretical basis was laid a preliminary foundation of information cooperative of metropolitan forest and greening resources monitoring.3) A method was put forward to construct information cooperative architecture of metropolitan forest and greening resources monitoring. A Frame work was proposed of this system. The system was studied in five aspects which was index system, management subdivision, survey, updating and application service.
