Research On The Construction And Upgrade Of Marine Ranching

The construction of marine ranching is one of the important future productions of marine fishery. From the realistic demand of marine ranching:significant decreasing trend of offshore fishery resources in our country shows, the excessive expansion of marine aquaculture industry, brought a list of side effects, not only seriously affects its own development, also destroyed the original ecological environment, forming a vicious spiral. Relying solely on traditional aquaculture has been unable to ensure the sustainable development of marine fishery. As an environmental friendly farming methods, building the marine ranching has become one of the most important solutions for sustainable development of marine fisheries and marine habitat worsening, has also got recognized by the community, including government and enterprises. From a practical point of view of the development of marine ranching:over the past ten years, our country in the field of marine ranching are a lot of practice and exploration, and have made certain achievements in promoting fishery yield increase, improving the marine ecological environment, and so on. But in general, the research and construction of marine ranching is still in the primary stage of construction of artificial fish reef is released and the proliferation of marine ranching. The absence of the government’s top of marine raching construction design, lack of targeted ocean circulation, tax policy and other objective conditions, actual construction of defrauding the government policy of subsidies appeared altering the construction plan to increase investment reef density, and so on. In addition, the overall efficiency of marine ranching play seriously enough, throwing in the artificial reef is equivalent to the construction of marine ranching, one-side pursuit of marine raching aquaculture effect leads to marine raching not give full play in improving undersea habitat, and pulling re-employment of loss of sea fisherment in coastal areas, and so on; even appeared due to the blind construction of underwater habitat is difficult to repair the damage, and one-sided pursuit of seafood bottom sowing culture caused by parts of the ocean ecosystem changes and so on. Improvement of marine ranching mode, giving full play to the superiority of marine ranching become an urgent issue in the practice of marine ranching. From the present research situation of marine ranching of view, since 1980’s, The domestic research for marine ranching are mostly focused on the concept, significance of demonstration of pure theory of interpretation, or artificial marine ecological cultivation technology, control technology and biological behavior of water environment monitoring technology to guide specific construction behavior of natural science and technology research and development, Study on marine ranching, management has not yet systematic, in-depth analysis of the factors of marine ranching in the construction and the construction of participant decision-making behavior is insufficient, ignored the analysis on the current marine ranching modes are summarized, affect the sustainable development of marine ranching.The dissertation takes the empirical study and normative study combined, through mathematical modeling and case studies, on the basis of prudent to clarify the connotation of marine ranching features, composition structure, properties, and on the role of significance, summarized the theory of the construction of marine ranching experience, the impact on the marine ranching building evaluation and analysis of the factors. In the construction of the marine ranching three main parties involved in stakeholder analysis based on the use of game theory to analyze the decision choices ocean ranch building government, enterprises, fishermen, and provides a reference for the further improvement of marine ranching construction mode. Combined with foreign experience in building marine ranching, construction on the state of the marine ranching country empirical analysis, summarized the development of marine ranching problems arising in the course of our country. Marine raching construction mode has been improved innovation, combined with the development trend of information technology, marine ranching proposed future upgrades shape-intelligent marine ranching. Finally, based on the study on China’s marine ranching and puts forward some countermeasures and suggestions.The dissertation contents are as follows:1、The basic theory research of marine ranching. In the system foundation of the summary of domestic and foreign research achievements on marine ranching, the basic theory is mainly an overview of marine ranching, the concept of marine ranching, the structure and characteristics were summarized and described, types of marine ranching are divided, and the function and attribute analysis, to establish a relatively complete and perfect of marine ranching the theoretical framework.2、Study on the factors of marine ranching and its influence. Mainly carries on the summary of the marine raching on the location, construction process, construction and environmental impact of the system summary. On the basis, factors influencing the system induction of marine ranching, and using the analytic hierarchy process, establish the system of evaluation and analysis on Influencing factors of marine ranching, to explore the various influence factors on the related representative of marine ranching, in order to provide a beneficial reference to the planning and construction of marine ranching.3、Construction of marine ranching interests Game Theory. From the perspective of the interests of the relevant, analysis of three major participants in the government, enterprises and fishermen of marine ranching in the interest relations, the establishment of game theory model, by using the game theory to the three major benefits of marine ranching in related party location decision analysis, explore the optimal decision of all participants in the selection of marine ranching.4、Analysis of the current situation of marine ranching. Analyzed the status of the domestic marine ranching development, on the basis of the domestic and international marine ranching and domestic different areas of marine ranching were compared, absorb the beneficial experience of marine ranching abroad, finds out the existing construction of domestic marine animal husbandry field problem, improved to better guide the follow-up of marine ranching mode.5、Research on innovation strategy of upgrading marine ranching. Based on theoretical research and empirical analysis on the former marine ranching, and studied the development trend of Chinese marine ranching. Firstly,combined with the previously discussed lack of marine ranching exists in the construction of our country, according to the nonprofit marine ranching and farming by type of marine ranch building their own characteristics, and puts forward the construction of marine ranching innovation orientation mode. Secondly, combined with the current development of each industry informationization, integration of the various industrial development of information technology, intelligent current trend, the concept of wisdom marine ranching, building characteristics and the wisdom of marine ranching composition structure, combined with the SWOT-AHP analysis, wisdom facing the construction industry marine ranching environment analysis on this basis, the use of the sunk cost theory of the wisdom of the greatest threats facing the ocean ranch building-expected return on investment of less than analyze and propose solutions to better promote the construction of wisdom marine ranching upgrade.Through the chapters of analysis, this dissertation proposes to promote the four aspects of Chineese marine ranching countermeasures:Firstly, improve the policy environment of marine ranching. These pecific includes:(1) The establishment of specialized management institutions for marine ranching. (2) Strengthening the construction of infrastructure, such as strengthening the marine ranching construction planning, improve the onshore facilities construction, improve the marine pasture production conditions, the construction of infrastructure investment,etc. (3) Increase financial support for tax policy, for example, improve the financial and credit policy, tax preferential policies, improve the financing environment. (4) Sea circulation policy innovation. (5) Improve the legal system, such as a sound management system, formulate scientific and market access policy, building the marine ranching investment property protection system etc. secondly, compaction of marine ranching market foundation. These pecific includes:(1) The integration of marine resources, promote the rational allocation of resources, enhance the ability of resource integration. (2) Innovative ways of capital operation, the introduction of PPP model in the public welfare of marine ranching, the marine ranching enterprises encouraged the integrated operation of direct financing, project financing, bond issuance and other means, to improve the financing capacity, reduce the cost of financing. (3) Using of the scientific research supporting role. Thirdly, to improve the marine ranching industry organization degree,these pecific includes:(1) Optimize the allocation of resources of sea area. (2) To strengthen the cultivation of marine ranching of leading enterprises, give full play to the demonstration effect, the comprehensive advantages of capital, technology and use it to drive the vigorous development of the construction of marine ranching in the waters around. Fourth, exploration of the construction of intelligent marine ranching, these pecific includes:(1) To improve the policy support ability, in the waters of examination and approval, the collection of taxes and fees and other aspects to the wisdom of marine ranching moderate to tilt, making scientific wisdom marine ranching construction planning, strengthen the government management and service efforts, started escort construction as the wisdom of marine ranching.(2) To improve the ability of information technology security. (3) Expand the financing channels of the wisdom of marine ranching.
