从大丰县生态演替史看淤长型滩涂的开发与利用

大丰县生态演替过程是典型的淤长型滩涂的自然演替过程,人类活动的干予极大地促进了这一演替进程。以脱盐改土为中心的水利建设和一系列农田基本建设是加速自然生态系统向良好的人工生态系统演替的有效措施。在此基础上综合发展农、林、牧、渔业是开发经济的基础,在发展以本地农、林、牧、渔产品资源的加工业的同时,注意到本县的其他优势行业,将促进该系统的协调稳定与繁荣。重视新垦区的教育与科技等事业的建设,将促进社会经济自然环境的全面发展。在淤长型滩涂上的盐业,不但对其本身不利,也阻碍该系统的演替进程。

A STUDY OF THE EXPLOITATION AND UTILIZATION OF THE DEPOSIT-ENLARGEMENT TYPE SEABEACH BASED ON THE HISTORY OF ECOLOGICAL SUCCESSION IN DAFENG COUNTY, JIANGSU PROVINCE

The process of ecological succession in Dafeng County is the process of natural succession of 3 typical deposit-enlargement type seabeach. The intervention of man s activies greatly accelerates the process of this succession. The construction of water conservancy which is centered on the desalination and improvement of the soil and a series of capital construction of the farmland are efficient measures to accelerate the succession from a natural ecological system to a good man-made ecological system. The inter grated development of farming, forestery, animal husbandy and fishery on this basis is the foundation for developing the economy. When developing the processing industry of the products of local farming, forestery, animal husbandy and fishery, attention should be paid to other superior industries. This will promote the stability, harmony and flourish of this system. It will promote the all-round development of the social ecomony and the natural environment to attach importance to the causes of education and science and techonology in the newly reclaimed area. The salt industry on such seabeach not only is unfavourable to itself but also hinders the succession of this system.
