Study On The Potential Of Land Improvement

Our country has a large population, limited number of cultivated land resource,land reserve resources woefully inadequate, contradiction between people and land are becoming increasingly acute, the economic development of our country is in rapid rise period, the phenomenon of construction land occupied the agricultural land is inevitable, large area of the cultivated land decrease will cause direct to our country’s food security threaten.At the moment, limited arable land resources in our country is still in disease, the infrastructure construction occupy the cultivated, water and soil loss, land desertification and the phenomenon about extensive use land. The cause of our country the man-land contradiction more important, land comprehensive reclamation, is an important measures of coordinate the relationships in our country and promoting the sustainable development of land resource; land comprehensive reclamation is an effective measures to improve the land utilization; The land reclamation potential measurement and classification is the important core of overall planning in land-using, as well as an important basis of land management, The study of potential land management system, has a great significance.In this paper, starting form the present situation of foreign and country land management potential, the main points are as low:First, the background and meaning of the topic selected of this thesis and introduces the concepts and theoretical basis of the doctrine;Second, analysis of the land reclamation potential measurement and classification method, In allusion to farmland improvement potential, the renovation potential of construction land, appropriate regulation potential reserve resources, land reclamation potential study of measurement and classification method, to determine each farming class corresponding research methods;Thirdly, empirical study. Based on the AHP (analytic hierarchy process)method, multi-factors integrate appraise method, frequency distribution histogram method,use some professional software in allusion to farmland improvement potential, the renovation potential of construction land, appropriate regulation potential reserve resources, land reclamation potential march detailed calculation and grading, provide important basis of Huai Yang Xian land management work;Fourthly, conclusion. Introduction to the deficiency of this paper, include land reclamation potential has a weak theoretical significance, the calculation of some data lack of scientific rationality, the potential classification has certain error.
