Research on ecosystem change monitoring and intelligent analysis system based on remote sensing data

Ecosystem monitoring is crucial for regional sustainable development. Taking Henan Province's Yanjin County as the study area, this research constructed an ecosystem evaluation index system including vegetation coverage, water quality, and land use based on Sentinel-2 satellite image data from April to September 2023. Through remote sensing feature extraction and change detection methods, the spatiotemporal changes of regional ecological elements were analyzed. The results showed that the highest NDVI value was 0.86, the water area increased by 12.3% during the flood season, and the construction land increased by 3.2 square kilometers. The overall monitoring accuracy reached 87.5percnt;, providing a scientific basis for regional ecological environment management.
