Abstract
Monitoring forestry ecological projects is vital as a fundamental task of forestry management and ecological construction. To supervise project application and adjust forestry policies, a research area in Yunyang County in Chongqing was selected as a demonstration area based on available high-resolution data, forest resource inventory data, and basic geographic data. Through feature extraction of remote sensing images, the Otsu threshold segmentation method, and object-oriented classification, research was conducted on an algorithm of reforestation site identification, forest extraction, and forest type isolation for forestry ecological projects. Results showed a high-resolution remote sensing application technology system which satisfied the operational requirements of dynamically monitoring forestry ecological projects. The system integrated data management, afforestation checks, dynamic forest resources monitoring, and forestry-related products to produce a demonstration system. The combination of high resolution satellite image and remote sensing application technology was sufficient for management and construction of forestry ecological projects and could improve the technological level for examining and monitoring national forestry resources.
