Study On The Cultivated Land Quality And It’s Obstacle Factors In Land Remediation Project Area Of Xin Yuan County

Adequate food supply is the foundation of the regular operation of Chinese economic and social, arable land as the carrier of food, its quality directly affects the crop productivity and the future of food supply problems in China. This study has certain reference value to the quality of research farmland. This paper studies Xinyuan County, land remediation and land quality and obstacle factors, evaluation of Xinyuan county land quality and analysis of cultivated land productivity, research Xinyuan County District land development project land obstacle factors based on the proposed recommendations for improvement and provide the basis for cultivated land in late stage of development and construction. The important research findings:First, Will research area according to different terrain, respectively establishes evaluation index system to evaluate, the research quality of arable land, the weight of every index by expert experience, analytic hierarchy process(AHP) acquisition and processing of data, to ensure real and effective in conclusion.Second, In this paper, according to the characteristics of the new development of arable land, follow the basis of certain principles and select the appropriate evaluation method. In this paper, analysis on the quality of arable land, it combined production capacity to analysis the utilization of arable land.Third, Analysis shows that the arable land quality face different obstacles, review of larger and comparison, the performance significantly influence factors are the following: soil thickness is thin, imperfect irrigation and drainage facilities, road network density is low, less part of the land exist slight salinization, soil texture was not suitable to plant survive.Last, Xinyuan County in the future development and utilization of arable land to pay attention to analyze the obstacles, perfect management measures, improve the ability of fertilization, improve agricultural infrastructure construction, breeding through binding, fallow crop rotation, rational adjustment of agricultural structure and other measures to ensure farmland quality validly use and steadily raise.
