Study On Low - Yielding Field Reconstruction And Soil And Water Conservation Engineering In Qifeng District

Our country is an agricultural country, agriculture is the foundation of the development of national economy [1], cultivated land as a guarantee the most basic means of agricultural production, its development and utilization and the national food security and social stability has a very close connection [2]. Our country is a densely populated country, with the population increase gradually and gradually reduce the land, is less than the more prominent.According to the no. 1 2008 rural work, the food security and solve the problem of "agriculture, rural areas and farmers" as the primary task of agricultural development, implementing "three always"(food security alarm always sirens, strengthen agriculture as the foundation of string always tight, solve "three agriculture" problem as the top priority of the party work requirements should always adhere to the). In response to a file called for, national and local government introduced a series of corresponding JiangNong favorable policies and measures. The middle-and-lowyielding fields is not only the restriction factors of grain production increase, is a great potential to improve food production. Although the lower-yield fields is to solve the problem of "agriculture, rural areas and farmers" and the important way to realize rapid and sustained development of agriculture, but from the perspective of a long-term development goals, the lower-yield fields development potential is bigger, although at this stage in the nationwide lower-yield fields has achieved initial results, but there are still many key problems need to solve [3].Based on the above background, based on the theory of scarce land resources, the production are described, on the basis of economic theory, comprehensively and systematically introduces the present situation of lower-yield fields in our country, the system analysis of seven lower-yield fields in the peak district and soil and water conservation engineering in the regional economic development and social sustainable development status and role, and the difficulty and necessity of seven peaks village reconstruction, in detail elaborated the seven peaks lower-yield fields in the community and the general situation of the regional soil and water conservation project, the construction and management situation, and from the viewpoints of economic, social and ecological benefits produced by the project were analyzed. Based on this, puts forward seven lower-yield fields in the peak district and countermeasures and relevant Suggestions on the development of soil and water conservation engineering [4].
