Research On Well-facilitied Capital Farmland Construction In Raohe County

With the rapid development of national economy, continuous progress of urbanization and continued population growth,the quantity of arable land in our country is decreasing, the obvious contradiction between people and land relations,arable farmland protection situation is worsening,and China is a fewer arable farmland and more people country.The reserve resources of cultivated land are seriously insufficient. It is not realistic to develop the quantity of cultivated land in large scale through the development of reserve land resources. Therefore, it is urgent to seek a new breakthrough in the quality of cultivated land and grain production. Well-facilitied capital farmland construction refers to the basis of soil fertility farmland make improvements, water conservancy, roads and other infrastructure construction, ecological protection of farmland to strengthen the capacity of the final management and maintenance work to deepen the comprehensive land remediation activities. Through well-facilitied capital farmland construction is helpful to cropland standardization, mechanization, scale of the joint implementation, agricultural work ability, farmland irrigation and drainage capacity, production capacity of arable land promotion, to improve the quality of cultivated land, improve land producti vity is important, safeguard national food security, to speed up the development of modern agriculture and promote the new rural construction of a major move.As part of the essence of arable farmland,and also well-facilitied capital farmland focus areas construction of arable farmland. In this paper a comprehensive analysis of relevant research progress of domestic and foreign as well as domestic basic connotation and theoretical basis for the well-facilitied capital farmland construction on arable farmland in the Sanjiang Plain in Heilongjiang Province Raohe County region as the research object of this study, on the border region Raohe County all basic farmland construction selected potential well-facilitied capital farmland were evaluated and graded, and then based on the evaluation results delineated construction scheduling well-facilitied capital farmland.Research indicates:(1)Construction of well-facilitied capital farmland is a delicate process in the framework of the objectives of the establishment of multi-factor comprehensive analysis from the natural.Endowments of basic farmland,agricultural resources rationing of condi tions select 10 index build well-facilitied capital farmland construction potential evalution index system.Using AHP and entropy method with the index weight, reference “farmland gradation”results in the assignment criteria.Well-facilitied capital farmland construction potential evaluation system.Then using the weight average method is calculated for each assessment unit of the individual scores for all evaluation factors, and the overall score of evaluation unit.Determine Raohe County well-facilitied capital farmland construction scheduling.According to the results of the evaluation of potential construction.Using natural breaks method in Arc GIS9.3 software to construction potential grading of Raohe County well-facilitied farmland.Raohe County is divided into the farmland of the basic conditions of the region with well-facilitied.Little improvement area, requires a comprehensive remediation area.(2)The basic conditions of the region with well-facilitied capital, mainly in the northern plains region and western hilly area of Raohe County. Respectively Jiansanjiang branch of Hongwei farm, 859 farm, Shengli farm,Hongxinglong branch Hongqiling farm, Raohe farming. The high quality level farmland, distribution concentrated, superior natural conditions, the area is divided into short-term construction. Slight improvement mainly in the area of the eastern plains region of state-owned land(Dongfanghong Forestry Brueau), Jiansanjiang Branch of Shengli farm,Raohe farm of Hongxinglong branch. The level farmland soil organic matter content and the effective thickness of the low value, the field of road accessibility in general, less farmland protection forest area, mainly by improving the farmland ecological environment, improve farm roads and farmland protection construction and other projects to make regional production conditions have been improved in order to meet the requirements of a well-facilitied capital of capital farmland, built-up area is divided into medium-term; It requires a comprehensive remediation area, mainly in the eastern plains region, western and southern hilly area, mainly for the state-owned land(Dongfanghong Forestry Bureau), Hongxinglong branch of Raohe farm,Liu Lan village, Jilong village. The level of capital farmland natural endowments poor road accessibility is not high, field engineering is not perfect protection, distribution of scattered plots, agricultural infrastructure is not sound. For a comprehensive renovation to the study area, we should focus on the implementation of related projects, such as land formation works, irrigation and drainage systems and farm- shelter forest project. Classified as long-term construction zone.
