Dynamic Update Method And Systematic Service Of Regional Forest Resources

Updating the dynamic change of forest resources is always the core of forestry work.The purpose of the research is to investigate the key issues in the dynamic update method of regional forest resources,combine with the annual examination and evaluation of ecological index and forest resource indexes by the government,and establish a dynamic update method and system based on the second-class investigation background data of forest resources,by utilizing all forestry business systems as the mutant data source and the growth model as the gradient data source.The main research contents are as follows.(1)Based on the analysis of growth and decline changes of forest resources as well as previous research achievements,the major factors,principle of gradual change and mutation causes for change of forest resources are discussed,and the gradient,mutation and overall models for the dynamic update of regional forest resources are determined.(2)The process,contents involved and internal relations of dynamic update of regional forest resources are studied,and the dynamic update mode of regional forest resources is systematically analyzed and designed,including system architecture,data sources and acquisition,data exchange mode,and update method.(3)A corresponding dynamic update system of forest resources is developed based on GIS technology,network technology and interface technology,and the dynamic update of regional forest resources is put into systematic service and application verification.The dynamic update method of regional forest resources based on internet+ established in this study organically combines the main mutation elements and types with gradient models of forest resources.It can be used to track the forest resources changes within plots in real time and automatically calculate the targeted value of plot and forest resource state,so that the timely update and plot evaluation of “sub-compartment” regional forest resources can be initially realized.The established platform automatically extracts the existing business system data,and,based on the analysis of modelling,presents the changing process of forest resources in an all-around and visual way.
