As the development of economic, emission of pollutant and environmental protection become more and more important, these are also closely related to sediment transport problem.

而且随着经济的发展，污染物排放处置、滩涂促淤围垦和海洋环境保护等方面的问题日益突出，这些问题都与泥沙输运密切相关。

In this thesis, bathymetric maps in 1958, 1980 and 2004, and ArcGIS software and Digital Elevation Model were employed to examine the spatial distribution and temporal variation of coastal wetla...

本文根据不同时期的长江口-杭州湾地形图，采用GIS、数字高程模型等，得出长江口-杭州湾北岸滩涂在1958年、1980年和2004年的分布状况[0m，2m，5m等深线以上的滩涂面积及其空间分布]，分析滩涂面积的变化及其与长江来沙和围垦等的关系，最后尝试对今后10-20年滩涂的冲淤趋势做出预测。

The habitat condition was more diversifiable and complicate.

河口上游区域的大面积围垦造地及环境污染是降低底栖动物食性功能群多样性的主要原因，缺乏杂食和碎屑食者，且肉食者物种很少，说明了区域生境破碎化明显，导致营养源的减少以及食物链的简单化。

For the reclamation of tideland and introduction of Spartina alterniflora , an evil invasive plant into the tidelands, the habitat for Hooded Crane is faced with serious threats.

近年来，由于滩涂的围垦开发及互花米草的入侵和扩散，白头鹤的栖息地面临着严重的威胁，亟待采取保护措施。

From Nov.2003 to Aug.2004,the macrobenthic community and niche analysis at creeks in diked tidal flat in 1997 were studied at Lingkun Island,Wenzhou City,Zhejiang Province.

2003年11月至2004年8月，在浙江温州灵昆岛选取了1997年围垦的潮沟断面，进行了潮沟大型底栖动物群落和物种生态位研究。

On such a basis, it concretely discusses the effects of the cultivation on ecological environment and holds the view that the damage of the original hydro geological environment by over-cultivation in South-East China results in the serious situation of "no reservation of water and no irrigation when drought" and thus greatly increases difficulties in flood prevention. Local governments through ages act on their own way without cooperation among diked paddy-fields in different areas and therefore local floods take place every year due to breakdown of the dikes. The great shrinking of lake areas because of too much reclamation affects the function of lakes in adjusting water volume and destroys ecological conditions of the area, leads to frequent disasters.

在此基础上，具体探讨了圩田开发对生态环境所造成的影响，认为因过渡围垦破坏了江南地区原有的湖泊河流水文环境，造成&水不得停蓄，旱不得流注&的严重局面，这便给圩田大大增加了防患水灾的压力；历代地方政府在圩田管理方面也是各自为政，各地圩田缺乏相互间的协作，使因破圩而形成的局部水灾年年有之；大量构筑圩田，使湖泊面积大为缩小，影响其调节水量的功能，破坏了本地区的生态条件，致使灾害频频发生。
