Abstract

Arable land resources security problem is an important issue for the survival and development of mankind. Arable land resources is the essence of the land resources, is one of the countries most basic strategic resource. Cultivated land security is the national food security, social security and ecological security of the most powerful protection, the direct impact on China's economic development and social stability. China's rapid economic and social development process to handle the arable land resources supply and demand balance, safeguard the relationship between food security, one of the key issues is to ensure the sustainable development of arable land resources. Huailai County, their geographic location and future ring the capital of the green economy Circle its already determine the direction of development, the new direction of development will inevitably put forward new demands for resources and the environment, to meet the social and economic development of the arable land resource consumption demand, protect arable land resources, arable land resources in the development of the state of health, safety, and will be an arduous and urgent task. Therefore, the area of ??arable land early warning system to expand the theoretical and empirical research has a very important significance. The paper access to domestic and arable land resources early warning of literature on the basis of a security point of departure from the area of ??cultivated land resources based on the food supply and demand balance, theoretical and empirical studies commence early warning system of arable land resources in the qualitative description of arable land resources security and early warning indicators system based on the proposed technical system of early warning research of cultivated land resources and research methods. Constructed on the basis of the arable land resources Temporal and spatial fluctuation a double warning model coefficient pressure index on cropland and the coefficient of relative production capacity of supply and demand as the goal of early warning and warning degree characterize progressively defined. Take the research methods of mathematical statistics analysis and econometric model, the form of a combination of theory and practice from theory, method, index system and early warning technology of arable land resources early warning system. And the measures proposed to promote the healthy operation of the area of ??arable land resources, to provide a reference for the area of ??arable land resources security research. The main conclusions are as follows: (1) to further understand the concept of arable land resources warning \. \(2) with a yellow warning method to establish early warning indicator system of farmland resources, determine a target warning coefficient build early warning model of arable land resources, divided warning warning degree level, determine the research area of ??cultivated land resources security warning degree, made analysis police intelligence. (3) years 2011-2017 Huailai County farmland total supply amount is less than the total demand of the arable land, arable land as the most important resources of police intelligence police; 2018-2020 arable land resources security state for police; arable land resources security situation gradually improved each year. (4) Huailai County 2015 171 villages of arable land resources exist the giant warning system performance for K ≥ 0 and -1 ≤ R ≤ 0; 16 villages of arable land resources exist a heavy police system performance for K ≥ 0 and R ≥ 0; The three villages of arable land resources exist serious giant warning system performance for K ≥ 0 and R lt; -1; villages arable land resources in the presence of light warning system showed K lt; 0 and - 1 ≤ R ≤ 0; 88 villages arable land resources there are no warning systems performance: K lt; 0 and R ≥ 0. (5) 2020 Huailai County 131 villages of arable land resources exist the giant warning system performance for K ≥ 0 and -1 ≤ R ≤ 0; 18 villages of arable land resources exist a heavy police system performance for K ≥ 0 and R ≥ 0; The three villages farmland severe resource giant warning system for K ≥ 0 and R lt; -1; 127 villages farmland resources there are no alarm system performance: K lt; 0 and R ≥ 0.
