| 摘 要： | 通过对渤海湾西岸粉砂淤泥质海岸带的现代地质作用调查与分析,阐述了渤海湾海岸带在现代地质作用下侵蚀和淤积并存的现状:目前潮间带上部在不断淤高,而潮下带则存在侵蚀,正处于淤蚀过渡期。遥感资料及沉积物粒度的进一步分析,认为渤海湾西岸现代地质作用的影响因素及海岸带淤积泥砂主要来自岸滩下部及浅海区的侵蚀作用。提出在海岸开发中注意防淤的同时,高度重视侵蚀作用可能对海岸带造成的危害。

| Abstract: | By the modern geological survey and data comprehensive analysis of silt muddy coastal zone,it is suggested that modern geological action,erosion and accumulation coexist on the west coast of Bohai Bay,China.At present,upper part of the intertidal zone is being accumulated,and meanwhile subtidal zone eroding,so intertidal zone is in the transitional period from aggrading to eroding.Based on further analysis of remote sense data and grain size data of sediment,the authosr discuss the influence factors of modern geological action and the source of sediment that aggraded coastal zone at west coast of Bohai Bay: the mud and sand coming from subtidal zone and shallows are the dominating source that result in deposited in the upper intertidal flat.In the end,authors presented future development tendency of tidal flat on west coast of Bohai Bay,and insisted that not only prevent accumulation but also the erosion should be payed more attention to in the coastal development. |
