Claim 3:
4. A continuous monitoring system for forest stock, characterized in that it is used to complete steps (4) to (7) in the continuous monitoring method for forest stock according to claim 3, comprising:
a user login and management module, configured to log in to the continuous monitoring system for forest stock;
an intelligent sample plot data receiving and storage module, configured to receive and parse intelligent sample plot data, save the data to a forest sample plot spatio-temporal database, and update the database;
a remote sensing change detection module, configured to obtain remote sensing change determination maps in two consecutive periods by using multi-period remote sensing images;
a remote sensing determination map survey and editing module, configured to complete input of remote sensing interpretation map factors after on-site verification and file update of remote sensing interpretation maps;
a sample plot stock computation module, configured to compute stock of each sample plot and stock of each sampling population in the current period by using updated sample tree survey information in the forest sample plot spatio-temporal database;
a forest resource change database generation module, configured to update base period forest resource subclass data by using remote sensing interpretation map verification results, obtain a forest resource change map through graphic and attribute comparison analysis, and compute current period forest resource subclass stock and forest stock variation;
a forest stand model update computation module, configured to compute a dynamic model update parameter, and obtain a forest stock variation caused by current period forest stand structure changes;
a sampling precision and eigenvalue computation module, configured to generate sampling precision and eigenvalues of the monitoring population by statistics;
a monitoring spatio-temporal database update module, configured to add timestamps to current period results for archiving and storage after the current period results are qualified upon precision test;
a monitoring result computation and statistics module, configured to collect statistics on main indexes and statistical data tables of monitoring results.
