Research And Development Of Close-to-nature Forest Management Aided Design System

Since the close-to-nature forest management technology introduced and practised in our country, more and more researchers have joined the study of close-to-nature forest, and paid attention to it. Firstly, the close-to-natural forest concepts and the present research status domestic and abroad are introduced in the paper, and then the research purpose and meaning of the close-to-natural forest management are also described. According to the two aspects of the theoretical and technical systems, the related close-to-natural forest knowledge is summarized.In addition, to satisfy the requirements of the forest construction and development, the close-to-natural forest management aided design system is developed based on the visual basic 6.0 development language and Access database, and the C/S (Client/Server) architecture system is adopted as the development mode. The system is a visual assistant system, which can realize the functions, such as the data management, data statistic, distribution map, dynamic growth, growth model, and operational design etc. The system can set up unifeid template for the database table, improve the integration and utilization, satisfy the information requirement of forest management, realiza the space position distribution map of tree, and help to determine the goal of improvement-selection cutting. According to the dynamic analysis, the influences of the management actions to the forest indexes can be investigated in time, help to establish and adjust the working plan. The system can be maken forest management more scientific, automatic and standardized, and provide an assistant decision-making tool for the proper managing of the close-to-natural forest management, realizing the sustainable development and classification management of forest resource, and making suitable management decision.Finally, taking the data of Beijing Locust Forest as example, the proposed system is applied in the Beijing Locust Forest, and the related functions are realized successfully.
