以科技创新工程为统领全面推进现代科研院所建设

目的]农业生态-经济系统是人地关系地域系统的重要组成部分,对该领域的研究也成为目前地理学、生态学和管理学等学科的前沿热点问题,众多学者从出于不同目的和角度进行了大量研究,取得了丰硕的研究成果,对已有的农业生态-经济系统研究进行梳理和总结,可以使其研究特征和不足更加清晰,以明确未来的研究方向与趋势.方法]应用归纳分析法和比较分析法等,对现有国内外农业生态-经济系统耦合协同发展的有关研究进行系统性的归纳总结,重点从农业生态-经济系统协同发展的理论认知、耦合协调度与耦合类型、发展模式、仿真模拟与影响因素、研究模型方法和研究时空尺度等几个方面归纳总结了所取得的研究进展.结果]农业生态-经济系统研究在经历了初期主要的理论探讨和定性的分析之后,相关研究已转入到定量化上来,同时发现现有研究存在指标科学性欠佳、方法运用单一化、尺度合理性欠缺和视角广泛性不足等问题.结论]农业生态-经济耦合系统协同发展研究正在探寻一条新的道路,即未来农业生态-经济系统耦合协调发展研究趋势为尺度微观化和长时序化、方法多元化、内容复合化.

WITH SCIENTIFIC-TECHNOLOGICAL INNOVATION PROJECT TO PROMOTE CONSTRUCTION OF MODERN RESEARCH INSTITUTES

Agricultural ecological-economic system is an important part of the regional system of human-land relationship, and its research has become a hot topic in the field of geography, ecology and management. Many researchers haddone abundant research from different targets and views, and made a great achievement in agricultural ecology-economic system. By the methods of induction and comparison, the article summarized the coordinated development of agricultural ecology-economic system both at home and abroad, includingthe theoretical cognition, coupling coordination, development model, influencing factors, research methods and research scales of agro-ecological system. And then it pointed out the problems in the present research such as insufficient evaluation index, the simplification of method, rationality shortage of research scale, and limitation of research perspective. Finally, it put forward the trend and prospect from the aspects of research scale, diversification on research method, and recombination on research content.
