WETLAND ECOLOGICAL ENVIRONMENT MONITORING IN SICHUAN PROVINCE BASED ON WIRELESS SENSOR NETWORK SECURITY

China's total wetland area is more than 65.9 million hectares, the wetland area accounts for 1/10 of the world's total wetland area, but China has not developed an effective measure to manage all kinds of resources, uncontrolled reclamation leads to a sharp decrease in China's wetland area. In order to better protect the wetland environment, wireless sensors are used to monitor the ecological environment of all wetlands in Sichuan Province in real time. Based on the Landsat remote sensing data in 2010 and 2020 in Qionghai Prefecture, Sichuan Province, and supported by wireless sensor technology, this paper interprets remote sensing images using remote sensing observation and interpretation technology. The ecological environment comprehensive assessment index (CEI) was obtained based on the ecological environment system health index, and the landscape pattern of wetland in this area was predicted. The index results show that the change of land use pattern significantly reduces the area of cultivated land and water, increases the patch density and destroys the landscape elements, and the wetland area in Qionghai decreases 436.5hm2. The coverage quality of vegetation was degraded by enlarging the coverage area of medium and low matter and reducing the coverage area of high vegetation. The ecological environment grade of wetland in Qionghai region of Sichuan province is grade iii . The change response, structure state and health status of wetland are not ideal when the ecological environment increases the pressure of wetland. In this paper, a CEI comprehensive index prediction model was established in Qionghai Lake, and the predicted ecological environment index was 0.524 in 2022. The comprehensive index of ecological environment of wetland in Qionghai lake region has been continuously decreasing, and the ecological environment of Qionghai lake has been continuously deteriorating by 2020.
