Study On The Development Model Of Ecological Agriculture Of Small Watersheds In Arid Area

In the background of economic globalization, With the deepening of the conflict between human activity and natural ecological environment, transform the pattern of economic development, taking the road of sustainable development has become the general consensus around the world. Agriculture was born along with human civilization, as the productive sectors most closely associated with nature, achieve the sustainable development of agriculture not only directly related to human existence, and for two or three industries provide a solid foundation for the sustainable development. Currently, ecological agriculture has to be recognized as the environmental damage the smallest, greenest most sustainable agricultural development mode in some countries have been successful in practice.China, the world’s largest developing country with huge population, conforms to the historical trend of the ecological agriculture is at the beginning of this century, exploration and practice. However, for a nearly half of arable land is arid and semi arid land in countries to ensure basic supply of 1.3 billion population, and realize the development model of ecological agriculture in arid areas is a subject not evade. New generation of Central collective leadership in the development of Chinese transformation nodes with the times presented "five concept" and four "comprehensive" strategy, Accurate poverty battle started and the supply side structural reform battle, for the transformation of agricultural development to create a favorable policy environment and provide a strong security system.Gansu province tongwei County as China Northwest drought district of typical representative,with national good of policy environment, relies on full film double ditch broadcast dry for agricultural technology, achieved has from past of "Schock crops" to now of "hardcore crops",from won national Ministry of agriculture "food production advanced units" to among State "food production big County", from "province cattle sheep farming big County" to "Gansu ecological cycle agricultural model County", Total broke the drought on Agriculture strong constraints to achieve grain output, agricultural efficiency and increasing peasant’s Butterfly, out of a drought in dryland agriculture sustainable development in poor mountainous areas, forming a development model of ecological agriculture in arid areas. This paper select Niuguhe basin as a case study areain tongwei County, through field research, interviews and other forms of access to first-hand data and typical cases, From the perspective of regional theory, summarizes the development model of ecological agriculture, forming the evaluation index system of the ecological agricultural development mode, and put forward suggestions for further improvements. Natural ecological conditions similar to those of agricultural development in arid and semi-arid region has some reference significance.
