Development of ecological agriculture in the several major obstacles
present, although the theory of ecological agriculture in China in the research, experiment and demonstration to promote the popularization has made great achievements, but can not deny that there are still some problems. These problems are becoming limited further obstacle to the development of ecological agriculture. Theory is not yet complete ecological agriculture is a complex system engineering, it needs to include agriculture, forestry, animal husbandry, aquaculture, ecology, resource science, environmental science, technology and social sciences, including processing support a variety of disciplines. Previous studies, often single discipline, so this may be one aspect of a complex system to a certain extent, and even more in-depth understanding, but also the interaction between these poorly understood. Therefore, further from the system, integrated perspective on the ecological agriculture more in-depth research, especially the coupling between the elements of law, the structure of the optimal design, the scientific classification system and objective evaluation methods. Such research should be based on the existing model of ecological agriculture in-depth investigation based on the analysis must go beyond the biology, ecology, social science and economics to the boundaries, should be multidisciplinary and comprehensive, requires multiple subject experts to participate, you need to establish ecological agriculture, the theoretical system of its own. Technology system is not perfect in an eco-agricultural system, often involve a variety of components, these components are very complicated relationship. For example, to raise ducks in the ponds, we must consider the number of breeding ducks, while the number of ducks will be the exchange rate of the water, the reservoir volume, water quality, type and number of fish species, water temperature, age and size of the duck and many other conditions. In general, farmers do not have enough theoretical knowledge and experience of the design of complex systems science, and simply copying the experience of another place, is very difficult and often not successful. But the practice of ecological agriculture, a lack of technical measures study how to develop both traditional technologies, but also how to introduce high-tech issues. Policy, there need to be perfected without government support, it is impossible to be truly universal ecological agriculture and development. The Government's support, the most important thing is to establish an effective incentive mechanism and security system policy. Although China's rural economic reform was very successful, but implementation of policies for ecological agriculture, and many deserve to be perfected. In some places, due to policy reasons, so farmers can not land, water and other resources for effective protection. Factor prices in agriculture, and sometimes the development of ecological agriculture has also become a limiting factor. Because for the poorer population, food security may be more important; but for those better-off farmers, high cost, may be stimulated to engage in a fundamental driving force of ecological agriculture. Service levels and capacity building can not meet the requirements for the development of ecological agriculture, services and technology are equally important. But has yet to establish an effective service system, in some places, farmers are unable to provide high-quality varieties, seedlings, fertilizer, technical support, credit and information services. For example, credit facilities for the development of ecological agriculture in many places is very important, because of ecological agriculture for farmers engaged in for profit may tend to get a few years of project implementation, in this case, credit services,tory burch outlet (http://www.toryburchshoes-outlet.net), is of essential. In addition, the information service is the current constraints of the important aspects of the development of ecological agriculture as an effective information service will be very beneficial to farmers to adjust production structures to meet market requirements, and obtain higher economic returns.
In addition, although the necessary incentives are necessary, but the ecological agriculture should be more inclined to develop a mechanism to enable farmers to participate in this voluntary activities. Voluntarily in order to mobilize the broad masses of farmers and self-reliant economic development through eco-agriculture, capacity building will naturally become a very important issue. So far, there is no established mechanism for more effective capacity-building, even more important for the grass-roots farmers, with little high level of training and learning opportunities. The industrialization of agriculture is not high the fundamental purpose of development of ecological agriculture is to achieve ecological, economic and social benefits of reunification, but many rural areas in China and promote economic development and improve people's living standards is still an urgent task. At present the actual situation of ecological agriculture can not meet this demand, because in some places, the development of farming alone, it is difficult to obtain higher economic returns. China's accession to WTO, both for the development of ecological agriculture in China offers new opportunities, but also so that faced with new challenges. To adapt to this new situation, the development of ecological agriculture and many of the issues to be resolved, of which, the industrialization of agriculture is undoubtedly a very important aspect. From another perspective, the population problem in China's social development has been one of the main. It is estimated that by 2030, the Chinese population will reach 1.6 billion. Relative shortage of land resources, cultivated land area has been reduced, while the population continued to increase, the transfer of rural surplus labor in rural areas has become plagued a major obstacle to sustainable development. To solve this problem, it must extend through the chain of ecological agriculture, promote agricultural industrialization level to achieve. Organizations shortcomings in the process of development of ecological agriculture, the organization is an important aspect of building. As the World Commission on Environment and Development in its report Because these institutions are independent and are often one-sided, with some narrow-minded decision-making process are closely related. China's current ecological agriculture, also less than the existence of such organizations. Although inadequate promotion of ecological agriculture has a long history, the Government is also more attention, but still not be replicated across the country. 101 state-level eco-agriculture counties, compared with the national is a very small number. Because in general, the heavy population pressure, the irrational use of natural resources, the overall deterioration of ecological environment has not been fundamentally improved, agricultural non-point source pollution in many places is still very serious. Soil erosion, land degradation, desertification, water and air pollution, ecological functions of forest and grassland degradation, has become a constraint in rural areas, the main obstacle to sustainable development. To some extent, the current pilot ecological agriculture, but also just But we believe that as long as we continue to work, ecological agriculture of the
