Research On Decision Support System For Improvement Of Low Function Plantation In South China

Previous forestry decision support systems mostly combined with GIS,using C/S or B/S architecture,users for forestry technicians and scientific researchers with professional background.This research aims at providing a simple and easy-to-use smart forestry APP for the majority of forest farmer users in forest land management.It implies the technology of ecological function upgrading and the industrial model in the practical technology of management and management.It attracts the first-line forestry users through the practical technology and industrial model of forestry management so as to improve the economic benefits as to induce the unconscious promotion of ecological services in the process of management.Functional objectives.We should change the single mode of improving the ecological safety of the low function plantation by upgrading the transformation project.Taking the "Internet plus forestry industry"as a link,we can promote the development of ecology and economy synchronously through the effective and stable development of the guidance and practice of ecological economy.Based on the theory of ecology,the spatial analysis of large geographic data,cloud technology and mobile internet,the system accurately analyses the suitable planting location of plants and advanced technologies for improving and industrializing the ecological functions of plantations,integrates the transformation of low-function plantations and the industrialized management mode of forest products,and designs and develops the large data-spatial information technology.The four-tier decision support platform of ecological function upgrading technology-practical technology and industrial model will eventually provide open services in the form of smart forestry APP.According to the development trend of market and technology,this system is based on Linux kernel,MySQL database,DTGeoServer and Android operating system framework,uses JAVA integrated development technology,integrates Android development technology,builds C/S architecture,designs distributed storage analysis system framework,stores and manages multi-source heterogeneous,geographic large data.Based on MVC design pattern and SSH application integration framework,the server-side design and development of cloud-side service application program interface for decision-making support of low-function plantation in South China was carried out.According to different types,grades and main afforestation species and socio-economic basis of low-function forests,the spatial structure optimization model of tree species precise suitability and ecological function improvement was used to determine different forest species and different regions.The upgrading and transformation technology and industry models of tree species are transformed into practical technology,product model,brand model and market model according to users’demand psychology.Client is "Smart Forestry",which directly provides land management,practical technology and business model,product release,online trading,traceability and other functions.Among them,"land management" is the link of user’s simple application.Users only need to choose their land location on the map or locate automatically by GPS on the site of the land,and do not need to add other information.Through decision-making to support large-scale data analysis,they can accurately obtain the service information of related technology and industry,and can operate other functions.This system is designed and developed on the basis of the research on the low-function forest grade type,ecological function calculation,ecological function promotion mode and technology of different forest species,industrial mode and so on by other members of the project team.The service side of this system adopts the technical mode and relevant mathematical model of each subject,and the system mainly realizes the programming.The large geographic data share the large geographic data platform with 90 m resolution of Beijing Geotechnical Corporation,and on this basis,the decision support database of low-function forests in South China is established.
