Research On The Sustainable Development Of Regional Agriculture Based On Complex System Theory

The sustainable development of agriculture has become the focus in the world into the new century. As a new development theory, idea and strategy, the sustainable development of agriculture has accepted by different ideology, social system and belief in different countries after it had appeared in the United Nations Conference on Environment and Development. The study on the sustainable development of agriculture, which has multi-interdisciplinary trend, is a merging process on one topic. In recent years, many experts and researchers has made a lot of study on the sustainable development of agriculture at home and abroad. Although the research has got some achievements, the research almost used the qualitative analysis and simply quantitative analysis so that it cannot reflects the essence of the sustainable development of agriculture. The sustainable development of agriculture is a multi-objective, multi-level dynamic, and open complex system made up by many factors such as agricultural economy, technology, and agricultural society. These kinds of problems have strong random uncertainty and grey characteristics. In this matter, the paper uses some theory and method of system analysis such as the random analysis, the grey system to do scientific study. There are seven chapters in this paper: The first chapter: the background, the basic concept, the connotation and characteristics of the sustainable development of agriculture are proposed, the recent research on the sustainable development of agriculture and the problems are discussed, and the research framework and main content are given.The second chapter: an overall systematic analysis of the sustainable agriculture of agriculture is described by the basic theory of complex system, including the basic factors and interactions, system objectives, basic characteristics and research methods of system theory.The third chapter: the building discipline, aim and model of the evaluation index system of the sustainable development of regional agriculture are put forward by the study of the connotation and denotation of the sustainable agriculture and factors of development of the sustainable agriculture.The fourth chapter: the sustainable synergetic mechanism of sustainable agriculture system is studied, which consists of inner mechanism such as basic connotation, dynamic mechanism and information feedback.The fifth chapter: the quantification problems of sustainability and simulation of the sustainable development of agriculture are analyzed. Firstly the quantitative analysis and evaluation on the recent systematic sustainability by power function; then the collaborative calculation model of the sustainable development of agriculture is built by grey system dynamic model, grey correlation analysis model and neural network simulation.The sixth chapter: the empirical study of sustainable development of reclamation area in Heilongjiang province is posed by the theoretical method in this paper, and the countermeasures and suggestions are provided.The seventh chapter: the main conclusion and outlook are summarized and the future research direction is pointed out.
