Research on the Optimization Method of Spot Monitoring Technology for Comprehensive Monitoring of Forest and Grass Ecology in Guangdong Province
Based on the annual update of patch data fusion of the third national land survey and forest re-source management"one map",the comprehensive monitoring of forest and grass ecology patch monitoring re-sults have been formed.However,there are still various issues with the monitoring of pattern data,such as few sources of the changed map patches,connections between multiple platforms,and differences in standard defini-tions,which lead to imbalance in data updating and poor realism of results.This study analyzes the characteris-tics of investigation and monitoring of forest and grass wet resources in Guangdong province,and adopts optimi-zation methods such as expanding the sources of change patterns,connecting multiple monitoring platforms,es-tablishing departmental joint review mechanisms,and formulating attribute logical relationships to improve the current situation and consistency of monitoring results data.Based on the analysis of the monitoring results of map patches in Guangdong province in 2023,the optimization method of forest land has doubled the number of verified changes in map patches.The inconsistent class map patches of the two departments after fusion have been identified consistently,and the logical relationship of the content of the attribute fields after verification has been reasonable.The results indicate that the optimization method of forest and grass ecological comprehensive monitoring spot monitoring technology can effectively improve the current situation of spot monitoring,and fur-ther provide data support for the green and beautiful ecological construction in Guangdong province.
