摘　　要：研究放牧经济活动对草地资源的利用有助于提出草地资源的适应性管理建议.以内蒙古锡林郭勒盟典型草原为研究区域,根据NDVI数据和经济资料数据,在家庭牧场尺度分析草场NDVI值及其与畜产量关系,并分析家庭牧场规模差异对草地资源的分异性影响.结果表明,2004年是研究区家庭牧场NDVI值转折期;生产规模大的家庭牧场其草场NDVI值相应高,反之则低;在研究期内样本家庭牧场NDVI均值与牲畜年产量均值序列相关,NDVI均值与牲畜单位面积产量呈反向趋势.由此建议,完善草原牧区产权制度体系;引导家庭牧场规模化生产和管理模式,避免差异规模形成的分布性过牧情况;草畜平衡管理制度要考虑对家庭牧场牲畜单位面积产量的控制;以区域研究和实证方法建立草原研究不同领域不同界面联系.Researching the grassland resource utilization of households can help to make reason- able proposals for adaptive management. By taking the typical grassland of Xilinguole League in In- ner Mongolia as the research region,this paper researches the NDVI value and livestock production index based on household ranches, it also analyzes the different influence of grassland resource ranch on the household variation scale. The results show that,2004 was the NDVI value turning point;the NDVI value with a large scale production was relatively higher,and that with a small--scale pro- duction was relatively lower;during the study period,the mean NDVI of sample households was re- lated to cross--section data sequence of mean annual production ~ and the mean NDVI showed a re- verse trend with the production per square kilometer. At last, the paper makes the following propos- als：improve the property right system of a prairie pastoral area; guide household ranches for a large --scale production and management mode, to avoid distributive overgrazing formed by scale differ- entiation;the grass livestock balance management should consider the control of the production per square kilometer; establish the correlation among different fields and different interfaces based on the regional study and empirical approach, to make tangible adaptive management proposals for the grazing production system with the household unit.
