摘　　要：为了摸清四川省剑阁县草地资源状况,于2018年6~8月,通过现场核实和样方调查等方法对剑阁县草地资源进行了实地调查。结果表明:剑阁县草地图斑相较于第一次草原资源普查和国土二次调查减少了260个,现存草地图斑仅41个,86.86hm^(2),其中未利用草地面积占52.78%、轻度利用占45.16%、中度利用占2.06%;全县的天然草地类主要是暖性灌草丛、热性灌草丛2类,草地型为具灌木的野古草、暖性禾草型,具乔木的白茅、芒型,具灌木的白茅型,具乔灌的扭黄茅型4个;暖性灌草丛、热性灌草丛的草地盖度分别为81.8%、87.83%,平均鲜草产量分别为9644.48kg/hm^(2)、13632.76kg/hm^(2),可食牧草产量分别为20143.02kg、209986.67kg,理论载畜量分别为18.40个羊单位/年、207.75个羊单位/年。In order to determine the status of grassland resources in Jiange County,we used on-site verification and sample survey techniques to collect data from June to August 2018.The results showed that 260 grassland patches were reduced in Jiange County,compared with the first survey of grassland resources and the second survey of land.There were only 41 existing grassland patches,with a total area of 86.86 ha.Among them,the unused grassland accounted for 52.78%,the lightly utilized grassland accounted for 45.16%,and the moderately utilized grassland accounted for 2.06%.The natural grassland mainly consists of two types:warm-temperate shrub tussock type rangeland and tropical shrub tussock type rangeland.The grassland type was wild ancient grass with shrubs,warm grass type,Imperata cylindrica with trees,awn type with shrubs,Imperata cylindrica with shrubs.The grassland coverage of warm-temperate shrub tussock type rangeland and tropical shrub tussock type rangeland were 81.8%and 87.83%,respectively.The average fresh grass yields were 9644.48kg/hm^(2) and 13632.76kg/hm^(2),respectively.The edible forage yield were 20143.02kg and 209986.67kg,respectively,and the maximum theoretical livestock carrying capacity of the whole Jiange County 18.40 sheep units/year and 207.75 sheep units/year,respectively.
