深圳河河口历史成因分析及综合整治建议

深圳河干流经过30多年的治理,防洪能力显著提高,水质环境也得到一定的改善。但是,河道淤积一直是困扰深圳河治理一个难题。造成深圳河中下游河段淤积的一个重要原因是深圳河河口存在一个大范围三角洲滩涂淤积区,滩涂泥沙在浅水风浪下扬动、随涨潮流上溯进入深圳河。本文在分析了深圳河河口演变历史及其成因,在分析现状问题的基础上提出了下阶段开展深圳河河口综合治理的建议。所得结论可为相关研究提供参考。

Analysis on historical genesis of Shenzhen River estuary and suggestion on its comprehensive regulation

Since the regulation carried out for over 30 years， the flood control capacity of the main stream of Shenzhen River is significantly enhanced along with a certain improvement of the water environment therein. However， the sedimentation of the river channel is all along a problem to obsess the regulation of Shenzhen River. One of the important causations to cause the sedimentation along the mid-lower reach of the river is that a large scale delta-shoal sedimentation area is there at the estuary of the river； in which the shoal sediment therein moves up under the effect of the shallow water wave and then flows upstream into Shenzhen River along with the tidal current. The evolvement history of Shenzhen River Estuary and its genesis are analyzed herein and some suggestions on the implementation of the comprehensive regulation of Shenzhen River Estuary for the next stage are proposed on the basis of the analysis on the problems at present concerned. The conclusion obtained can provide some references for the relevant researches.
