摘　　要：[目的]探索一种比较简明的草地资源生产潜力评价方法,为今后昭苏马场草地资源充分、有效、合理的利用提供科学依据.[方法]在综合考虑昭苏马场不同垂直带11个草地资源类型草地地形、地貌、气候、水文、土壤和植被因素的基础上,通过大量的野外试验与室内测试,分析不同垂直带土壤的理化性质,应用Miami和Montreal模型对昭苏马场天然草地的生产潜力进行模拟分析.[结果]提出了昭苏马场天然草地生产潜力的分级方案,将昭苏马场草地资源承载力划分为“十二个等级”,从划分结果看,二等、三等草地面积为3 779.09 hm2,五～九等草地面积为22 674.55 hm2,十～十二等草地面积为18 895.46 hm2,分别占可利用草地总面积的8％、50％和42％,这与昭苏马场草地资源的实际状况是相符的.[结论]利用Miami和Montreal模型进行草地资源生产潜力评价,是一种适用于草地资源生产潜力快速、简洁、方便的评价方法.它能较准确、客观地反映昭苏马场草地资源生产潜力.【Objective】To quest for a more compendious way to evaluate potential production of grassland resources,which might provide a scientific basis for the fully,effective and rational usage of the grassland resources of Zhaosu Horse Farm in the future.【Method】In this paper,we analyzed the physical and chemical properties of different soil based on a lot of experiments according to the landform,physiognomy,hydrology soil and vegetation in the eleven resource types of natural grassland quality in Zhaosu Horse Farm;Simulate analysis of the grassland resources potential production in Zhaosu Horse Farm by using the Miami model and Montreal model was conducted.【Result】Based on the analysis results,the plan of twelve grades of natural grassland potential production in Zhaosu Horse Farm was put forward.From the dividing results,the areas of second grade and third grade are 3 779.09 hm2,and fifth to ninth are 22 674.55 hm2,and tenth to twelfth are 18 895.46 hm2.They account for 8%,50% and 42% of the arable grassland area,respectively.The results conform to the actual situation of Zhaosu Horse Farm.【Conclusion】Using Miami model and Montreal model for evaluating potential production of grassland resources is a fast,clear,and convenient way.It can reflect Zhaosu Horse Farm's potential production of grassland resources more accurately and objectively.
