Claim 4:
5. An execution method for the continuous monitoring system for forest stock according to claim 4, characterized in that it comprises the following steps:
(1) logging in to an application system by a user using the user login and management module;
(2) collecting and updating a current period sample plot tree database by using the intelligent sample plot data receiving and storage module;
(3) obtaining forest resource interpretation maps according to remote sensing images in two consecutive periods by using the remote sensing change detection module;
(4) obtaining an on-site survey database by using the remote sensing determination map survey and editing module after field survey, file update, and graphic and attribute editing of the forest resource interpretation maps;
(5) superposing base period forest resource subclass data on the on-site survey database to generate a forest resource change database by using the forest resource change database generation module, and collecting statistics on a forest stock variation caused by plot type changes;
(6) obtaining a dynamic forest stand model update parameter for plot type unchanged subclasses, updating stock of all the plot type unchanged subclasses by using the forest stand model update computation module, and collecting statistics on a forest stock variation caused by forest stand structure changes;
(7) computing eigenvalues of a sampling population, forest stock of sample plots, and stock of forest subclasses by using the sampling precision and eigenvalue computation module, and correcting data according to precision control requirements;
(8) outputting a current period result database and adding timestamps for archiving and storage by using the monitoring spatio-temporal database update module after results are qualified upon precision test;
(9) collecting statistics on main indexes and statistical data tables of monitoring results by the user using the monitoring result computation and statistics module on demand.
