[Abstract]:In recent years, under the new concept of green development, ecological agriculture has received extensive attention. Xiangxi is a traditional agricultural area, and it also belongs to the Wuling Mountain area. While developing, protecting the ecological environment is the theme of this area. In this paper, the ecological agriculture in Xiangxi mountainous area is taken as the main research object. By using the methods of literature analysis and analytic hierarchy process, the collected basic data and data are refined and analyzed, and seven typical ecological agriculture models in Xiangxi mountainous area are summarized. The paper also analyzes the opportunity of developing ecological agriculture in Xiangxi area, and draws the conclusion that Xiangxi region should make use of resource endowment, seize policy dividend, improve regional transportation network, and develop eco-agriculture vigorously. On the basis of consulting relevant literature and consulting experts and scholars at home and abroad, this paper makes a comprehensive evaluation of ecological agriculture in Xiangxi mountainous area from three dimensions of economic benefit, ecological benefit and social benefit by using AHP method. In terms of benefits, the following conclusions are drawn: horizontally, the ecological and social benefits of ecological agriculture in western Hunan are higher than the national and Hunan average levels, and the economic benefits are slightly lower than the national and Hunan average levels. The comprehensive benefit is higher than the national average level slightly lower than the Hunan average level, and the comprehensive benefit and its three benefits rise steadily year by year. This paper also studies the countermeasures and suggestions for improving the ecological agriculture benefit in the western Hunan mountainous area. Firstly, it is necessary to strengthen the planning and design and optimize the county layout of ecological agriculture. According to the differences of resource endowment in counties and districts in western Hunan, and the foundation of the development of each ecological agriculture model, this paper analyzes the distribution of typical models from the aspects of market demand, production factors, resource endowment, etc. The ecological agriculture model which should be popularized in western Hunan is put forward, and the county layout of ecological agriculture model is put forward through the analysis of industrial structure and the difference of resource endowment. Second, we should focus on specialization and scale, enlarge and strengthen leading industries, cultivate innovative production and management subjects, create ecological agricultural products brand, and promote the transformation and upgrading of ecological agriculture. Third, it is necessary to increase agricultural technology extension, speed up the popularization of scarce technology, increase scientific and technological innovation in ecological agriculture, strengthen the construction of eco-agricultural technology extension institutions, and provide technical support for the development of ecological agriculture.
