以宁夏固原云雾山草原自然保护区为中心向外呈辐射状布设监测调查样方,利用草地基况法和模糊综合评价2种方法对宁夏长芒草（Stipa bungeana）典型草原进行健康评价,并在评价的基础上提出宁夏长芒草典型草原健康评价标准体系。研究表明,1）长芒草典型草原用草地基况法的评价结果为云雾山、月亮山、南华山的草地处于健康状态,原州区、彭阳县、隆德县、西吉县、盐池县的草地处于健康但有问题状态,海原县、同心县的草地处于不健康状态;2）模糊综合评价法的评价结果为云雾山、月亮山、南华山为健康草地,原州区、彭阳县、隆德县、西吉县、盐池县为亚健康草地,海原县、同心县为不健康草地;3）按照宁夏长芒草典型草原健康评价标准体系将宁夏草地划分为健康、健康但有问题和不健康3个等级。%The outwards radial survey from centre regions were used to evaluate the health status of Stipa bungeana steppe by rangelang condition and fuzzy comprehensive evaluation in the Grassland Nature Reserve of Guyuan Yunwu Mountain of Ningxia province,and then this study proposed the health assessment standard system using the result of healthy evaluation.The results of this study showed that the grasslands of Yunwu Mountain,Yueliang Mountain and Nanhua Mountain were well health,and those of Yuanzhou,Pengyang,Longde,Xiji,and Yanchi County were sub-health,and those of Haiyuan and Tongxin County were unhealthy according to evaluation results from range condition methods.Based on the evaluation results from the fuzzy comprehensive evaluation method,the grasslands of Yunwu Mountain,Yueliang Mountain and Nanhua Mountain were well healthy,and those of Yuanzhou,Pengyang,Longde,Xiji and Yanchi County were sub healthy,and those of Haiyuan and Tongxin was unhealthy.This study proposed that the health assessment standard system of S.bungeana Steppes in the Ningxia included well healthy,sub healthy and unhealthy.
