摘要

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,利用草地基况法对宁夏长芒草典型草原进行健康评价.结果表明:云雾山、月亮山和南华山的草地处于健康状态；原州区、彭阳县、隆德县、西吉县和盐池县的草地处于健康但有问题状态；海原县和同心县的草地处于不健康状态.%The outwards radial samples were surveyed with Grassland Nature Reserve of Guyuan Yunwu Mountain as the center to evaluate the healthy status of Stipa bungeana Trin. steppe in Ningxia based range condition. The results showed that the grasslands of Yunwu Mountain, Yueliang Mountain, and Nanhua Mountain were in healthy status; Yuanzhou, Pengyang, Longde, Xiji and Yanchi's were in sub-healthy status; while Haiyuan and Tongxin's were in unhealthy status.
