摘　　要：以北方草地和农牧交错带草地类型区域分异为基础,重点考虑不同草地类型的生态系统服务功能,在综合分析了北方草地和农牧交错带生态环境基本特征的基础上,确定了草地生态功能区划的原则、依据、方法及命名,然后在"3S"技术的支持下,将北方草地和农牧交错带分为北方草原区、北方荒漠区和农牧交错区3个一级区及10个二级区,对各个功能区的区域范围、主要生态环境问题、主要的生态服务功能及为了功能区的保护与可持续发展而需要采取的措施都进行了详细论述。区划结果对认识北方草地与农牧交错带不同草地类型生态系统服务功能的重要价值,对草地资源的合理利用和农业生产的合理布局、对生态环境保护与建设规划及对维护区域生态安全、实现区域的可持续发展都具有重大意义。With a primary consideration of the ecosystem service function of different grassland types,and basing on the principles of regional planning,methodology,nomenclature,the features of regional eco-environment,as well as ＂3S＂ techniques,The grassland and agro-pastoral transitional zone in northern China was classified into 3 ecological regions and 10 eco-function regions.Then,the elaborations were carried out in detail regarding the territory of each function region,primary eco-environment issues,core ecological service functions and means to be adopted for protection and sustainable development of each specific function region.We believe that the developed regionalization result is very helpful in understanding the ecological service function value of different grassland types,facilitating effective use of grassland resources,promoting optimal layout of agricultural production,improving the regional ecological security,as well as strengthening the regional sustainable development in the grassland and agro-pastoral transitional zone of northern China.
