The farming-pasturing interlock region of the northern China is a typical and ideal zone for studying ecological environment background condition.The vulnerable ecological environment in this area is attributed to natural conditions and human activities.First,the study built the diagnostic indicators of ecological environment background condition,based on multi-subject spatial data that reflect the characters of ecological environment;then,evaluated the ecological environment by the use of the digital grid model and the spatial analytical method; next,analyzed the spatial pattern of ecological environment.The results are as follows:(1) The eco-environment background condition becomes worse from southeast to northwest in the farming-pasturing interlock region of the northern China.(2) The ecological environment background condition of the majority counties is moderate in the studied 205 counties,that of Yanchi county in Ningxia is the worst,and that of Xinglong county in Hebei is the best.

中国北方农牧交错带受自然条件和人为活动等多种因素的综合影响,生态环境退化问题比较突出,是生态环境退化研究的典型区和理想地带。以此作为研究对象,选择能反映生态环境特点的多种空间数据信息,利用数字网格模型,通过采用空间叠加的分析方法,评估北方农牧交错带的生态环境背景状况,并对其空间格局特征进行研究。结果表明:(1)北方农牧交错带生态环境背景状况从东南向西北逐渐变差;(2)在北方农牧交错带205个旗县中,绝大部分旗县的生态环境背景状况为一般;宁夏盐池县生态环境背景状况最差,河北兴隆县生态环境背景状况最好。
