Ecological Vulnerability and Ecological Risk Assessment of Shanghai Section of Hangzhou Bay North Shore

Abstract Vulnerability research and ecological risk assessment of coastal environment are great significance for the temporal spatial evolution process trend zone. In this paper, using 4-phase GF-1 remote sensing data, landscape fragility index artificial disturbance intensity Shanghai section north bank Hangzhou Bay calculated, variation characteristics response to human activities analyzed. The prediction based on Kalman filtering is used. area vulnerability level shore in 2022. results show that: (1) lower fragile dominant type vulnerable between 2013 2016, low-vulnerable rises 2016-2018, higher high areas rise, 2018-2019 change slower than previous stage. High-level continue spread, mainly from urban suburban, inland coastal, land port. (2) study has a significant activities, there positive correlation intensity. (3) Based filter method, predicting each 2022 that low increased moment, medium 2018, which 2019.
