一、前言随着上海市工农业生产和城市建设的发展,郊区土地被大量征用,耕地面积逐年减少,有必要重视滩涂资源的开发。而目前上海市沿海高于(?)3.6米的滩地已基本围垦利用,对中、低滩涂如任其自然淤涨,则速度极其缓慢。怎样选择合适的人工促淤方式和速度,是目前急待研究的课题。本文以上海市南汇县东滩为例,试就促淤方式和速度问题作初步探讨。
I. Introduction With the development of industrial and agricultural production and urban construction in Shanghai, a large number of suburban land was requisitioned, the area of arable land decreased year by year, it is necessary to pay attention to the development of beach resources. However, at present, the beach land 3.6 meters above the sea level in Shanghai has been basically reclaimed for use. As a natural siltation of the middle and low tidal flats, the speed is extremely slow. How to choose the appropriate method and speed of promoting siltation is an urgent subject for research. This paper takes Dongtan, Nanhui County, Shanghai as an example to discuss the method of promoting siltation and its velocity.
