摘要
受河口圈围工程、长江径流以及东海潮流复合影响,长江口横沙浅滩区域湿地生物多样性和生态环境不断发生变化.本项研究采用遥感分析、现场观测和调查、室内分析、资料收集等多种方法,对区域内地形地貌、底栖生物、鱼类、鸟类、植物以及水环境进行了系统调查和分析.结果表明该区域湿地生物多样性较为丰富,水质与生态环境较好,但近十年来地形和湿地生境变化较大,未来河口工程实施与建设对该区域的影响需要进一步监测和科学评估.
As a result of the complex interaction between the estuary enclosure human engineer ing, the Yangtze River upstream runoff, and the wave and tidal current from the East China Sea, the wetland biodiversity and ecological environment o{ Yangtze Delta Hengsha East shoal have been changing quickly and sharply. We use remote sensing observation data, field measurement, data analysis in laboratory and historical data collection to conduct a systematic investigation and analysis about the landform, benthic organisms, fish plants and water environment in the Heng- sha East Shoal. The results show that the diversity of the region is abundant and water quality and ecological environment is good also, The impact with estuarine engineering implementation and construction is on the need for further monitoring and scientific evaluation.
