Abstract:

In order to solve the problems in the current forest resources planning,design and forest inventory,a novel technology system of integrated aerial-space-ground forest resources survey and monitoring system was proposed and tested.This paper introduced the method for forest sub-compartment investigation factors setting and information acquisition.Compared with the traditional methods,this method lacks some factors which need to be recorded in the field,such as understory vegetation,natural regeneration and forest health status.However,the sub-compartment investigation factors of the novel technology system could still reflect the forest land and tree status(type,quantity,quality and structure),as well as the natural environment conditions.It can completely satisfied the requirements of forest resources management and statistics of forest resources reports in collective forest areas,and it also can meet the demands of various related applications for the basic data of forest resources.The basic attributes of sub-compartment(land type,dominant tree species,tree origin and associated tree species) need remotely sensed image interpretation and some supplementary field investigation,while the other attributes of sub-compartment can be obtained automatically by computer program.This method greatly reduces the investigation workload and labor force,while improves the efficiency and quality.The results indicated that it can effectively ensure the reliability of sub-compartment investigation data and the quality of forest resources inventory results.
