摘 要: | 崇明东滩是长江口规模最大、发育最完善的河口型潮汐湿地,又是一个河口淤涨型湿地,对1988年与2002年崇明东滩湿地卫星遥感图象的分析,得出以下几点结论:①崇明东滩并不是全部扩涨,南部滩涂岸线呈后退趋势;②在淤涨部分,以最东端最快;③随着长江上游来沙减少和大规模的围垦,崇明东滩的前景将不容乐观。因此,可持续开发、利用和保护崇明东滩湿地迫在眉睫。

Abstract: | Chongming Dongtan is a estuarine tidal wetland with the greatest size and the most perfect developed in the Changjiang estuary, at the same time, also it is a estuarine growing wetland. In this paper, through analyzing Chongming Dongtan SPOT images in 1988 and 2002, we have reached some conclusions;(1) Not all part of Chongming Dongtan is in growth,Chongming Dongtan southern part is withdrawing;(2)In the part of growth, the fastest is in the eastern;(3)With decrease of sediments from the upper reaches of the Changjiang and inning in a larger scale,the prospect of this region is not good. So, it is urgent to sustainable exploit, use and protect this area. |
