摘要为研究上海市水土流失及措施现状,以第一次全国水利普查水土保持情况普查结果为基础,结合上海市基本情况,分析上海市水力侵蚀现状和水土保持措施情况。结果表明,上海市水土流失面积超过了200 km2 ,水土流失以河道两岸和湖泊沿岸的坍塌淤浅为主要特征,建设项目施工造成的人为水土流失也是上海市水土流失的一个重要方面。上海市中心城区水土保持措施较完善,但郊区部分河道还没有采取有效护坡措施,基本处于自然状态,很容易发生水土流失;因此,河道边坡和湖泊岸线的护岸整治、海岸滩涂的保滩促淤治理是上海市水土保持工作的重点,同时还应加强建设项目的监管和水土保持监测,以防止人为水土流失。
Abstract:In order to study the current situation of soil erosion and conservation measures in Shanghai,based on the soil and water conservation census result of the China Census for Water, and combined with the basic situation of Shanghai, the paper analyzed the present situation of hydraulic erosion and soil and water conservation measures of the city. The result showed that the soil and water loss area covered more than 200 km2, and mainly occurred at the riparian zone. Furthermore, the soil and water loss caused by construction project is also serious. The soil and water conservation measures in city center is relative perfect, but that in suburb channels especially slope protection are not effective, which almost presented a state of nature, subsequently easy to loss soil and water. Therefore, the riparian restoration and treatment are key task for soil and water conservation in Shanghai. At the same time, in order to prevent artificial soil and water loss, we should strengthen supervision of construction project and monitoring of soil and water conservation.
