Research On Spatial Layout Evolution And Its Influencing Factors Of Marine Fishery In Zhejiang

Under the new econom ic norm,the marine economy has become an important economic growth point in Zhejiang province.But in recent years,with the im pact of resource depletion,environmental pollution,economic growth too fast and so on,the development of marine fishery to enter the turning point of the transformation and upgradi ng,meanwhile because of the unreasonable spatial layout,the healthy development of the marine fishery has been restricted.Based on the theoretical and practical significance,the domestic and foreign research results are useful for reference,so as to build a theoretical framework of the marine industry spatial layout and its influencing factors.Mainly from the evolution law of the marine industry spatial layout,the dynamic mechanism and the influencing factors of the three parts of the research and analysis.Exploratory spatial data analysis m ethod(ESDA)is used to analyze the spatial layout of Zhejiang marine fishery from the time and space dimensions.At the same time,according to the actual situation of the development of Zhejia ng marine fishery,respectively from the marine fishery science and technology,the fixed capital investment of marine fishery,marine fishery labor force,seawater aquaculture area and marine fishery resources in five aspect s to select factors influencing the spatial layout of marine fisheries,to construct marine fishery factors affecting the spatial layout model.In this paper,the empirical research results show that the spatial layout of marine fisheries in Zhejiang has been gradually formed in the center periphery of the layout mode,the overall trend of spatial agglomeration is more significant.But from the point of view of lo cal analysis,the marine fishery high value g athering area co ncentrated in the coastal area of East Zhejiang and the southward expansion of the trend,while the low value gathering area is mainly distributed in the southwest of Zhejiang Province.Spatial distribution of marine fishery in Z hejiang also showed significant differences in the distribution of longitude,and the form ation of Zhoushan-Ningbo-Taizhou as the core of the three center distribution pattern.In addition,through the analysis of the mechanism and empirical analysis of the factors affecting the spatial distribution of marine fisheries in Zhejiang,it is found that the marine fishery science and technology,marine fishery fixed capital investment and marine fishery resources of Zh ejiang marine fisheries spatial agglomeration has significant role in promoting,The capital factor is the most important influence factor,leading the other influencing factors to carry on the evolution of spatial layout of marine fishery.However the m arine fishery labor and seawater aquacu lture area fo r marine fisheries spatial agglomeration to hinder.At last,This paper from the construct efficient and intensive spatial layout,promote marine fishery production from offshore to deep sea development,strengthen the Ningbo T aizhou Zhoushan three core cluster and increase the investment in the development of marine fishery four aspects to p ut forward corresponding countermeasures and suggestio ns,in order to realize the reasonable optimization of marine fisheries spatial layout in Zhejiang.
