中国北方农牧交错带植被动态研究进展

通过回顾植被动态研究的历史，简要概述了植被动态的发展。综述了我国北方农牧交错带历年来植被动态的研究现状。研究指出植被动态变化与农牧交错带内气候、自然环境演变、农牧业经营方式的转变及土地利用有着密切的关系。结合前人的研究，根据农牧交错带内存在的生态环境问题，提出应从北方农牧交错带植被动态与生物多样性、生态环境、生态系统健康以及对全球变化响应的关系进行研究，揭示其受损及恢复机理，为农牧交错带受损的生态系统恢复与重建、区域可持续发展提供理论依据。

Trends and Advances on Vegetation Dynamic Research in Transitional Zone of Pastures and Farmlands in North China

Based on study reports and publications,the development of vegetation dynamics is summarized,and previous study of vegetation dynamics in transitional zone of pastures and farmlands in North China is reviewed.Changes of vegetation dynamics in transitional zone of pastures and farmlands in North China have an intimate interrelation with the climate,evolve of natural environment,transformation modes of management between agriculture and pasture and land use.Because of particular and important ecological functions of transitional zone,more attention should be given the research in future.Further research on interrelations of vegetation dynamics and biodiversity,ecological environment,ecosystem health and response to global change is an efficient key to revealing the mechanism being damaged and restored of its ecosystem,finding ways of regional ecology restoration,improving ecological environment, and realizing sustainable development.
