摘要
为了综合评价青海省共和县的天然草地质量,利用功效系数法和距离法对天然草地主要地面植被指数进行功效系数和评价距离计算,并对评价距离进行排序。结果表明:共和县质量最好的天然草地为华扁穗草型,质量最差的草地型为猪毛菜、驼绒藜型。评价结果与天然草地实际情况相符合,这说明利用功效系数法和距离法评价天然草地质量准确可行,可以推广利用。
For evaluating the quality of natural grassland in Gonghe county synthetically, the primary ground vegetation index was used to calculate the efficacy coefficient and evaluation distance by efficacy coefficient method and distance method. The results showed that the best quality natural grassland in Gonghe county was Blysmus sinocompressus Tang et Wang style, and the worst was Salsola L, Ceratoides lateens （J.F.Gmel.） Reveal et Holmgren style, which was accorded with practice. It indicated that the efficacy coefficient and evaluation distance could be used to evaluate the quality of natural grassland.
