北方农牧交错带界定的研究进展

作为农牧区的交汇地带,北方农牧交错带的生态环境十分敏感,是我国重要的生态屏障。本文基于前人的研究综述了农牧交错带的概念、形成、北方农牧交错带空间界定研究进展和气候变化对北方农牧交错带空间位置变化的影响。得出如下结论:前人对北方农牧交错带界定的研究多是定性化的,界定的范围只是大致的地理位置。气候因素是北方农牧交错带界定研究中的重要指标因素。建议:在定性化的基础上运用GIS等现代技术手段对北方农牧交错带进行更加深入的定量研究,从而更加准确地确定其地理位置和面积。并且考虑经济发展、政策制度、人类活动等人文因素的影响。

Research Progress of Definition of Farming-pastoral Zone in Northern China

As the intersection zone of the agricultural and pastoral areas,the eco- environment of the farming- pastoral zone in northern China is very sensitive,and the zone is also an important ecological barrier in our country.On the basis of predecessors＇ research,this paper reviews its concept,formation,research progress of space definition of the farming- pastoral zone in northern China and the impact of climate change to its spatial position change.Conclusion was made as follows： the predecessors＇ research is qualitative in defining the farming- pastoral zone in northern China,and the defined range is only an approximate location. Climatic factor is an important index factor in the study of defining this zone. Suggestions： on the basis of the qualitative study,using modern technology,such as GIS,to conduct more in- depth quantitative research,so as to determine its geographic location and area more accurately. And the influence of human factors,such as economic development,policy,system,human activities is worth considering.
