| Related research of ecological agriculture has been existing home and abroad, China’s establish of ecological agriculture take a long time, but due to lack of planning and research for models at the beginning of the establishment, the development was more blind. With the advancement of science and technology and agriculture, planning of ecological agricultural model is perfected gradually. However, most studies of ecological agriculture are concentrated in the areas of food and cash crops, less model of grass farming combining agriculture, lack of planning studies of grassland ecological agriculture. Based on the reference model of ecological agriculture planning on existing scientific research, through a combination of field surveys, analysis, summary and so on, through the combination of ecology, economics and cultivation and other disciplines, the use of comparison, analysis and planning means the introduction of forage and turf grass ecological agriculture system to the Golden Land agriculture Park in Gansu Province, to explore for grassland agriculture mode Gulang County, the study results are as follows:1. Gansu golden land company park plan to the ecological layout of "one network, two center, six districts,", "network" that runs through the production and development of the park ecological network; "two hearts" that the park command center and seed breeding center; "six districts "That office and living area, entertainment area, production and processing areas, crop areas, livestock areas and biogas district, and the district conducted a detailed functional division.2. Planning to crops, livestock and biogas three parts mainly grassland agriculture mode, crop sections of alfalfa and tall fescue introduction of ecological agriculture model, a "food-pasture-Economy" ternary structure of the grass field rotation mode to alfalfa forage provide animal feed, improve the ecological environment and improve soil nutrient, with tall fescue as cash crops, improve the economic benefits of ecological agriculture, potato crops to address food supply; breeding beef number of approximately 1904, the number was about 5,850 sheep, pigs number about 1964; methane biogas produced is used to power the region, serving the park use.3. Economic, social and ecological benefits of the park is completed the analysis, comprehensive evaluation of cropping systems economic value of 0.84, a comprehensive evaluation of the economic benefits of livestock breeding is 1.0012, Overall value of 1.8412, according to the relevant classification, comprehensive evaluation gradelt is good; the economic and ecological benefits of crop monoculture and mixed cropping mode analysis, three kinds of benefits under optimum crop rotation patterns; can promote local economic development project is completed, the employment rate increase for local farmers, and guide the development of local agriculture; the establishment of agricultural parks can maintain soil and water, prevent soil desertification, reduce wind, ecological environment protection. Through the construction of the ecological park planning after the expected economic, ecological and social benefits quantitative analysis, forming a complete ecological park planning and benefit assessment theory, economic, ecological development direction ecological park play a crucial role.4. According to the geographical characteristics of Gulang County, climatic factors, agricultural structure and rural development situation analysis, will be divided into four Gulang County agricultural area, it is recommended gentle arid northern desert forest should vigorously develop animal husbandry, animal husbandry, agriculture and animal husbandry; cold temperature arid central plains region should insist on animal husbandry and agriculture simultaneously, three can be neglected; low Zhongshan in south-central area of cold arid livestock farmers should be based on agriculture, livestock integration; the southern half of Central Asia alpine cold wet animal husbandry farmers should be the main area animal husbandry, forestry, animal husbandry combined model. Analysis and study of the characteristics of each agricultural area, are proposed agricultural production structure adjustment and development of recommendations. |
