浙江地处东南沿海,大小岛屿星罗棋布,有丰富的海涂资沅。解放后,特别是无产阶级文化大革命以来,沿海群众在“拦海造田,向涂要粮”与自然作斗争中取得了很大成绩。仅肖山一县,自1968年以来,已围涂三十多万亩。在生产实践中,群众已打破过去“长草围堤”(涂面高程大多在平均高潮位以上)的老框框。目前涂面较高的海涂资沅已逐年减少。初步调查表明,全省今后待开发的海涂资沅中,约有71%的海涂需要采取人工促淤措施加速海涂的淤涨,才能达到适围高程。如何采取人工促淤措施,以达到尽快开发利用海涂资沅的目的,已成为当前海涂围垦工作不容忽视的问题之一。近几年来,我省在这方面做了一些工作,下面作一简要介绍。 Zhejiang is located in the southeast coast, dotted with islands of size, rich sea-owned resources. Since the liberation, especially since the Great Proletarian Cultural Revolution, the coastal masses have made great achievements in the struggle against nature and in their struggle against nature. Only Xiao Shan a county, since 1968, has covered more than 300,000 mu. In production practice, the masses have broken the old frame of the “Longcao embankment” (with mostly painted surface heights above the average climax). At present, the high-coated Tuotezi Yuan has been reduced year by year. Preliminary investigations indicate that about 71% of the TACs to be developed in the future in the province need to adopt artificial stimulation measures to speed up the tide of the TACP so as to reach the suitable altitude. How to take measures to promote siltation by hand in order to achieve the purpose of developing and utilizing the Tujiayuan as soon as possible has become one of the problems that can not be neglected in current reclamation of the Tuhai Sea. In recent years, our province has done some work in this area, following a brief introduction.
