Research On Intensive Use Of Agricultural Land Of Henan Province

In economic development, population growth and agricultural land is limited and declining number of cases, by strengthening the input and output per unit area increased intensive use of agricultural land will become research priorities and focus in land-use problems. Thus the intensive utilization of agricultural land, currently limited to the intensive agricultural land resources, improvement of the comprehensive utilization benefits can be realized effectively alleviate food safety and environmental safety issues caused by resource are of important theoretical and practical significance.In this study, based on the establishment of a comprehensive evaluation system to learn the theory and research methods at home and abroad, using multi-objective comprehensive evaluation method and the entropy and other mathematical methods, with geographic information systems, the author studies the intensive use of agricultural land in Henan Province to conduct evaluation studies, and targeted measures are proposed to promote the intensive use of agricultural land in Henan province level. The thesis is divided into four sections: introduction; evaluation theory model; empirical research; conclusions and prospects.Section1: Introduction. First of all, the research background on the paper, meaning, content, methods, technical line, data sources and other issues are given a brief explanation and analysis of relevant literature are reviewed in order to grasp the intensive use of agricultural land characteristics and problems. The scientificality and reasonalization about the choice are also clearified.Section 2: Theoretical construction, including the second, third, fourth chapters. The author redefined the concept and content of intensive use of agricultural land, makes a distinction between the concepts, discusses the impact of intensive use of agricultural land factors, and the system sort out the basis for intensive use of agricultural land theory, making theoretical groundwork for further study. In addition, the design of the intensive use of agricultural land evaluation system is also laid out with a clear evaluation on the purpose and meaning, objectives and tasks, procedures and methods, building intensive use of agricultural land evaluation index system and evaluation model.Section 3: Empirical study. Case study is conducted in Henan Province. The causes of selection of Henan Province as a case study are briefly stated, and from the natural environment, economic environment and land use and agricultural use of the current situation, the study shows an overview assessment of the region. The chapter explain the use of intensive agricultural land evaluation theory and methods, combined with agricultural land use situation in Henan Province, using multi-objective comprehensive evaluation model, with the entropy method, the level of intensive use of agricultural land to its quantitative evaluation, revealing agricultural land in Henan Province intensive use of spatial differences, and the evaluation results are analyzed and judged, seeking to science, in order to quantitatively reflect the situation in Henan Province and the intensive utilization of agricultural land. In the end the author gives concrete and feasible policy recommendations for how to improve the level of intensive use of agricultural land in Henan Province.Section 4: Conclusion and Outlook. This chapter summarizes the main conclusions obtained in this study and awareness, while also addressing the innovations of this study, deficiencies and needs further study.
