Study On Coupling Mechanism Of Eco-agriculture And Ecotourism Under Constraints Of Resource And Environment

Eco-agriculture and eco-tourism are sustainable and able to upgrade China's traditional agriculture and tourism. By means of agricultural mechanization, large-land scale, technological innovation, and technical intensification, eco-agriculture promotes the level of agricultural productive forces, the original ecological level of agricultural products, and the farmer's income. And eco-tourism avoids the traditional tourism disorder to consume the resources intemperately and advocates developing tourism under the constraints of tourism carrying capacity so as to increase the taste of tourism products, the environmental protection, and the economic efficiency. At present, the major researches on the two fields are separate and independent. Although eco-agriculture and eco-tourism have already borne fruit in their independent domains, but there are still little continuous and dynamic analysis on the two industries and little research on the synergetic evolution mechanism, in particular, on the eco-agriculture and eco-tourism coupling mechanism and the factors restrict to its development.The research in this dissertation is very necessary for the Three Gorges Reservoir Area in the process of the economic transformation. Three Gorges Reservoir Area is rich in resources needed for the great development, but with the completion of Three Gorges Project, there have also been a series of new rural reconstruction problems yet to be resolved. First of all, the reservoir area is possessed of unique advantages for developing eco-agriculture. In addition, it is away from the industry-intensive areas and has barely-polluted soil and air, biodiversity, and comprehensive inter-species balance mechanism. Secondly, the reservoir area also has location advantages for developing eco-tourism since it is located in the golden section of Yangtze River Three Gorges Tourism gold lines, and it has the tourism industrial foundation and brand influence. Therefore, it is good to convert natural strengths and ecological advantages into commercial and economic superiority by the strong pull from eco-agriculture and eco-tourism. Moreover, the fragile ecosystem and the hollow of the industrial structure caused by Three Gorges Project and the relocation of migrants, in addition to the low-income status due to the traditional farming, call for a new type of coupling industrial system of eco-agriculture and eco-tourism in the area without intensive industries. Therefore, the research on the interactive mechanism of eco-agriculture and eco-tourism, and the industry growth path and constraints do not only provide suggestions for the industrial structure adjustment, changes of economic growth mode, and the new socialist countryside construction in the reservoir area, but also make a reference for the industrial structure adjustment in other regions and the sustainable development of other industries.This dissertation established a coupling industrial system of eco-tourism and eco-agriculture so as to maximize its social benefits and achieve the industrial dynamic optimization of resource allocation under the constraints of recourses and environmental capacity. It presented the influences of different types of resources (such as renewable and non-renewable resources, raw resources and secondary resources) on the economic growth of the coupling industrial system. It described the impacts of different types of pollutions (such as different decay rate, different environmental capacity) on the economic growth of the coupling industrial system. It also presented the effects of changes of such parameters as technology, industrial scale, industrial structure, etc. on the coupling system. Thus, it pointed out some suggestions on plans of the coupling system development and the macroeconomic policies.Based on the introduction of research background and significance, ideas and the content, features and innovations, as well as relevant theoretical researches, the dissertation conducted the research on the coupling mechanism of eco-agriculture and eco-tourism under the constraints of resources and environmental carrying capacity. The creative researches are as follows:â‘ The dissertation developed a frame of the coupling industrial system of eco-tourism and eco-agriculture. That is we connected the two industries organically in order to explore their interaction mechanism and factors. Furthermore, we considered two constraints, carrying capacity of resources and environmental carrying capcity, to disscuss the growth path and the optimization of eco-tourism and eco-agriculture.â‘¡Applying system dynamics and the theory of dynamic optimization, the dissertation described the inner workings of the coupling system under the constraints of resources and environmental carrying capacity, and considered the following key variables: subject, mode, resource, environment, technology, economic benefits and distribution.â‘¢According to the time-spatial differentiation of pollution control and industrial differentiation of economic benefit, the dissertation established a coupling system of ecotourism and eco-agriculture, which can achieve resource sharing and cooperative control of pollution:The dynamic optimization of resource allocation of the two industries under the constraints of resource and environmental carrying capacity. Using the dynamic optimization tools, the dissertation analyzed the optimal path of the economic development of the two industries under the constraints of resource and environmental carrying capacity and found the balance of their cooperative development. The influnces of different types of resources on the coupling system. The dissertation presented the distribution and use of different resources in the coupling system, such as primary resource, secondary resource, raw resource, renewable resource, analyzed the impacts of different alternative relations among resources on the coupling system and on the dynamic changes of different industrial scales and structures in the coupling system. The impacts of different pollutions on the coupling system. The differences lied in the stock of pollution, the pollution load, the environmental capacity, pollutants with different degradation rate, and pollutants in different industries.According to the different pollution and recource consumption in different industries, the dissertation described the dynamic changes of the industrial size and structure of the coupling system.â‘£Based on the above analysis, the dissertation selected a typical county in Three Gorges Reservoir Area to conduct a case study.
