Research On Digital Planning For Regional Forest Resources Based On Spiral Model

Forest resource management is the core issue of forestry of all the time, the key problem of realizing forest sustainable developments is to achieve sustainable management of the regional forest resource. With the development of modern high-tech, the wave of global information has pushed forest resource planning and design to be reformed in information and upgraded in technical. Traditional hand-based planning method and feedback backward, as well as the lack of systematic, holistic and integrated analysis has affected the science and adaptive of regional forest planning seriously.The development and application of spatial information technology which are based on 3S technical have a direct influence on the Efficiency, effectiveness and results. Forest resource digital programming is emerging from the global information and developing requirement of modern forestry. It becomes an inevitable trend that forest management in specific region has been changed into digital, integrated, intelligent and web-work by using new technology and programming theory. Under the opportunity of expanding regional forest resource planning theory and method, this paper take a comprehensive analysis to the present situation of regional forest resource planning. By taking forest sustainable management as the purpose and using systems theory, cybernetics, information theory, etc and digital engineering principles and methods, this paper, which considers the survey and analysis in regional forest resource planning, diagnosis and evaluation, planning approval and implementation of control and dynamic process feedback after the implementation and feedback as the main line, also discusses the digital methods in each period of regional forest resource planning based on systematic analysis of CAS, digital planning principle and the dynamic planning theory of regional forest resource. The main work focuses on the following four areas:i Proposes the dynamic spiral model of regional forest resource planning. For the fact that the idea of regional forest resource has been being changed to dynamic programming as the core of the profound revolution and based on analyzing the developing process of forest resource planning theory, this paper proposes the dynamic spiral model of regional forest resource planning which Simplifies the process into 4 sub-process such as background research, programming drawing up, planning implementation and feedback monitoring. The 4 sub-process are interlocking and in an iterative cycle. This paper studies the key digital technical and method by taking model as the main line.ii Analyzes and bring forward to the concept structure, theory chart and technical method of regional forest resource digital programming. It also made a lot of studies on the dynamic mechanism of programming and management in digital forest resources programming and introduced CAS and GA in order to realizing time and spatial prediction of forest harvesting model.iii Expanding the application of geo-informatics Tupu into forest resource management.The forest resource programming and the comprehensive managing informatics Tupu are a typical features informatics Tupu.
