摘　　要：采用相对资源承载力的理论与研究方法,定量分析了盐池县8个乡镇相对资源承载力时空变化及差异特征,并对承载力匹配特征进行空间表达。结果表明:盐池县辖各乡镇相对于盐池县的综合人口承载力表现出严重超载、超载和富余3种不同的状态;相对自然资源经济承载力时空变化稳定,自然资源的经济潜力不断增大;相对草地资源牲畜承载力随时间推移不断递增且空间差异明显;依据3种承载力状态组合划分了不同的承载力匹配类型,并提出不同类型的可持续发展策略。本研究可为盐池县禁牧10年后各乡镇发展提供建议,并为"退牧还草"政策的继续实施提供理论支持。Adopting the relative carrying capacity of resources theory and research methods, this paper ana- lyzed quantitatively the variation in space and time of the resources＂ relative carrying capacity in 8 township of Yanchi as well as differences among them, and gave a spatial expression of the matching characteristics of the carrying capacity. The results showed that： the carrying capacities of towns in Yanchi have three differ- ent states as being heavily overload, overload and surplus, compared with their comprehend carrying capaci- ties of population; the spatial and temporal variation of the economical carrying capacity of relative natural resources is steady and the economic potential of natural resources is constantly rising ; grassland＇s relative carrying capacity of livestock is constantly rising over time and the differences in space is obvious; and di- vided different carrying capacity matching patterns based on the combinations of the above three carrying ca- pacity states and further put forward different types of sustainable development strategies for those different states. This study can provide suggestions for towns in Yanchi, which are forbidden to graze for ten years, and provide theoretical support for the policy of ＂Return Grazing land to Grassland＂.
