其他摘要 | Based on the problem of agriculture ecological system and agriculture economy system severe imbalance in Gully Region of Loess Plateau, choose typical representative area Wangdonggou watershed in Changwu County Shaanxi Province as research object, study on its agriculture eco-economy system evolution process for over 20 years, explore the evolution stages, characteristics and driving factors of the agriculture eco-economy system, analysis the change of household economy in different stages, put forward the benign interrelation strategies for the agriculture eco-economy system. It provides reference for perfect research system of agriculture eco-economy system in Gully Region of Loess Plateau and provide scientific basis of sustainable development scheme of agriculture eco-economy system for the other similar areas in Gully Region of Loess Plateau. The main results are as follows.(1) Choice population, farmland, forestland, artificial grassland, orchard, yield, planting net income, fruit industry net income, the second and the third industry net income, animal husbandry net income, per capita net income 11 controllable variables, use SPSS software through hierarchical cluster analysis divide agriculture eco-economy system evolution process for over 20 years into three different stages, the first stage (from 1986 to 1993), named agriculture eco-economy system control stage, the second stage (from 1994 to 2003), named agriculture commodity economy construction stage, the third stage (from 2004 to 2006), named agriculture eco-economy system sustainable development primary stage.(2) In agriculture eco-economy system control stage, improve grain yield, land use and industrial structure obtained preliminary adjustment, increase planting net income, the second and the third industry net income, orchard promote the agriculture eco-economy system benign. In agriculture commodity economy construction stage, adjust the use land again, and optimization agriculture industrial structure, establish fruit industry leading position gradually, the main driving factors of stage development is fruit industry net income, the second and the third industry net income, the main limiting factor is farmland. In agriculture eco-economy system sustainable development primary stage, land use and industrial structure tended to be stable, the main driving factors of stage development is fruit industry net income.(3) On the process of agricultural eco-economic system transformation from the first stage into the second or third, farmers gradually changed their managing consciousnesses from irrational to rational. They raised income and improved living conditions through increasing the material input and carrying out production intensification. Gradually, main types of eco-agricultural developing such as “fruit-farm”, “fruit, farm-stockbreeding”, “fruit, farm-sideline” have been formed with the economic raising of farmers.(4) Analysis the strategic position orientation of agricultural ecological economy of Wangdonggou watershed, proposed strategic goal, strategic emphasis, and strategic mode.(5) National Benefiting-farmers policies, Great Development of the West and local governmental policies have brought good opportunities for agricultural eco-economic system development in Wangdonggou watershed. Meanwhile, the development will be confronted with some of challenges. So, what follows are the key points on the process of developing. Adjustment according to the local condition and developing the agricultural intensive production, making proper use of land resources and optimizing and updating industrial structure are primary. Secondly, strengthening the cultivation of farmers’ cultural quality and guiding farmers becoming rich through science and technology. Thirdly, developing the ecological agriculture of commodity economy and advancing the process of agricultural industrialization. And then, perfecting rural service system, strengthening infrastructures and improving agricultural ecological environment are also very important. Lastly, peasant workers should be trained before employing and the management of labor export should be strengthened and their legal rights should be protected. |
