Sustainable Use Of Land Resources Study

Land carrying the human economic development and production activities, is essentia for human survival and development of material basis. Production capacity of land resources and the stability of national security and social stability. With economic development, urbanization and industrialization process accelerated, there can not curb the amount of cultivated land reduction; Ecological restoration policy, industrial pollution, caused by natural disasters and other large land mass broken down. The reduction of cultivated land, decline in the quality of the grim situation has been a serious threat to the national economic sustainable development and social harmony. Stable production capacity from the perspective of sustainable use of cultivated land has practical significance and far-reaching social significance.Of cultivated land based on the theory of sustainable use of resources, from land use to ensure optimal land-use utility theory, the maximum benefit from the implementation of land intensive land use theory, Production potential of land from mining the land production potential theory and the stability of the natural quality of cultivated soil science theory, clearly defines the content of the sustainable use of cultivated land, that all the arable land in specific areas in a usable state is to protect the ecological environment, Promote economic growth and social prosperity and stability of long-term productivity. Sustainable use of land resources more emphasis on the sustainability of its use, coordination and fairness.Objective analysis of the cultivated land resources in Jilin Province, the quantity, quality, and the changes in recent years, analyzes the reasons for these changes, First, less land for construction control expansion, the second is caused by agricultural restructuring to reduce the number of arable land, three are soil erosion, ecological degradation and the formation of a balanced fertilizer due to decline in the quality of cultivated land.Guidance and in theory on the basis of objective analysis, combined with the actual Jilin Province, is proposed to maintain the production capacity of provincial land proposal that tap the potential of reserve land to expand arable land; Strict protection of cultivated land cultivated land resources, accountability ease the rate of decrease; Implementation of the billions of grain yield planning to ensure stable growth of grain production, sustainable production capacity of arable land.At last, this article concludes with the sustainable use of cultivated land resources in Jilin Province's countermeasures that the increasing national education efforts, and improve farmland protection-related laws and regulations; Strictly control the scale of new construction land, the implementation of land use control system; create farmland protection forest belt, great transformation of low-yielding fields; strengthen the governance of Soil and the eastern, western combat land degradation; attention to farmers to re-use of land surface, the establishment of Dynamic monitoring system of land protection.
