As HABs have occurred frequently these years due to the extra nutrition of certain oceanic districts, it is high time we implemented the blue print of the precaution and controls. Yet this project is a complex relevant to a large number of fields. And it is in desperate need of coordination from different systems and multilevel concerning ecology, environment, economy and society and the like. However, it is rather difficult for the current system of the precaution and control to meet the demand, for we tend to be confronted with the problems of low efficiency and feasibility of a sort. In this case, the key of the project rests with how to integrate theories of different fields so as to render a relative, specific, and effective guideline and shaping relatively integrated theory system of the precaution and control of HABs. The thesis chiefly focuses on how to boost the efficiency and strives to increase the feasibility of the project. Hence, the innovation is mainly relevant to the two aspects. More details are as follows:1 To probe into the cause of the interior mechanism of society and economy and come up with an innovative blue print to solve the problem. For instance, the thesis puts forward a plan to resolve how to sever the ownership according to the common issue in utilizing the environmental resources of certain oceanic districts. Another case in point is to discuss the feasibility of emitting deal based on Koth means. Additionally, the thesis seeks a key to the problem of information asymmetry in allusion to the ineffective management of the government.2 To found a system of the precaution and control of HABs and provide relati ve steps. For example, the thesis conducts a systematic research about the problem of excessively emitting of extra nutrition and puts forward a systematic thought to control and manage the project, that is, the emitting gross of extra nutrition-the evaluation of environmental effects-the permission of emitting-the system of targeting responsibility.3 To conduct a research measured by quantity concerning ecosystem and economic system in the process of outbreak of HABs, say, to establish dynamic evolvement models and the model about the relationship of input and output. In addition, the analysis of outbreak of HABs, the means of the precaution and control, and the appraisement of the effects lay a solid foundation for potential policies and the assignment of resources.4 To set up the system of guide line and appraisement in the project of the precaution and control of HABs. The system encompasses the estimate of the environmental capacity in certain oceanic districts, the calculation of HABs from the perspective of quantity, and evaluation system of the effects attributed to the project, which renders a reference for the establishment and implementation of relative policies.We may take a look at every single chapter respectively.Chapter 1 briefly aims at analyzing the cause and harms of the outbreak of HABs, and the advance and setbacks in relevant researches. Meanwhile it introduces basic theories especially Biku and Koth theories.Chapter 2 is to analyze the current system of the precaution and control of HABs, and point out principal problems existing in current management system. It also illustrates respective functions of politic and economic means in the process of the outbreak of HABs.Chapter 3 probes into the cause of the occurrence of HABs from the perspective of the mechanism of society and economy. Also, it analyzes the problems existing in the implementation of the policies of the precaution and control, and testifies the feasibility of them. Chapter 4 focuses on assigning and optimizing resources of the project, boosting the efficiency in utilizing resources, refining ecological quality of ocean, reducing the occurrence of HABs, and maximizing the economic benefits of society.Chapter 5 concentrates on setting up a series of ecological and economic models to prevent and control HABs, encompassing systematic structures, dynamic evolvement, and output-input optimizing models and so forth. Moreover, it makes full use of these models to conduct researches concerning HABs and input-output of the blue print.Chapter 6 illustrates how to take a good control of emitting of extra nutrition. What is more, it comes up with an idea for the purpose of changing the current controlling mode and establishing a systematic management chain, namely, emitting gross of extra nutrition-appraisement of environmental effect-the permission of emitting-time limit renovation-the system of targeting responsibility.Chapter 7 is to found the evaluating guide line to evaluate harms of HABs and the achievements of the precaution and controls, and to weigh rationality and validity of the work. In the meantime, it lays a solid foundation for the blue print through establishment of the objective evaluation system about loss, effects and benefits. Chapter 7 is mainly concerning the analysis of the problems existing in implementation of the precaution and control of HABs.
