Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource-depleting and polluting technology (T).
A wetland environment degradation identification processing method based on remote sensing image monitoring
ActiveCN120912910BTrue reflection of wetland conditionsCharacter and pattern recognitionSoil scienceWetland degradation
The application discloses a kind of wetland environmental degradation identification processing methods based on remote sensing image monitoring, method includes: obtaining original remote sensing image including multi-temporal data and pre-processing, through different time nodes different wave band remote sensing image, capture dynamic wetland environmental change, truly reflect wetland condition;Based on texture feature and spectral feature combination image between each region texture boundary transition clear value to the remote sensing image after pre-processing is implemented regional growth segmentation, obtain local area image, feature extraction result is combined by texture feature and spectral feature, so that subsequent image segmentation processing can take into account details and overall structure;Finally, based on local area image by pre-trained wetland degradation detection model is analyzed, obtains the type of each local area image, provides accurate data basis for the detection and remedy of wetland degradation.
