Under The Condition Of Typhoon Mangroves Along Sedimentary Morphological Analysis

Zhanjiang three facing the sea, with most of the transit route of tropical cyclone orthogonal, is most affected by the cyclone and one of the most serious areas, so the choice in this research area.This article first to the theoretical research of the flow pattern along the sedimentary often describes the conditions and under the condition of typhoon waves beach deposit form,(analytic solutions) with different formula express beach sedimentary patterns. To describe conditions and under the condition of typhoon waves often mangrove beach deposits form, summarizes the research achievements of predecessors. In Zhanjiang’s mangrove bay beach elevation data observation for a period of six months site, according to different forest parameters, the design of observation stations and measurement section, research before or after the typhoon, the response mechanism of mangrove coast, and the recovery process, analysis of mangrove coast sedimentary evolution law of the form. Then comparing the theoretical study and field test study, discussion of mangrove coast sedimentary process, summed up the mechanism of mangrove wave revetment, and briefly discuss the mangrove coast economy applicable value. Mangrove plant short, the following conclusion: under the condition of forest belt width is also small, along profile form similar to beach. Mangrove coast profile form is influenced by tidal significantly. Etched recover rapidly within the first week after the typhoon, the mangrove forests along profile dramatic morphological changes, as silting situation. Long have near the mangrove vegetation along seashores sediment in stable and regular wave tide, as sedimentation condition. Mangrove plant growth strewn at random discretion, spread out, there is a tide fork, waves come in shape in the form of development in the normal case, the deposition and erosion of the opposite. Mangrove plant forest belt width reach above 65 m, and leafy, previous to light under the condition of sex is extremely low, can maintain the stable development of along profile morphology. Mangrove vegetation growth height difference is great, and growing thin, forest belt width above 65 m, leads to development form of inverse effect, namely the erosion of deposition conditions, and vice verse. The deterioration of the global environment is influenced by many factors, resulting in destruction of one of the consequences of including coastal structure, in this paper, the results of the study of global change in the future, especially in the south China coastal areas, it is of significance to the protection and management of coastal zone.
