| 摘 要： | 于2009年对贡山县5个乡镇的天然草地类型与分布、牧草资源现状与分布进行了调查。结果表明，贡山县共有草地面积181 734 hm2，占全县总土地面积的26.35%；全县草地类型有5类、11组、60型；采集植物45科，193种，禾本科和莎草科各有40种和12种，分别占植物总数的20.7%和6.2%；其中可识别牧草类植物157种，食口性好的优良等牧草（87种）占牧草类植物总数的55.4%，中等牧草（53种）占牧草类植物总数的33.8%，而低等和不良牧草（17种）仅占10.8%。贡山县草地存在的主要问题是草地资源分布极不均匀，草地局部退化严重以及侵略性害草危害严重。针对这些问题提出了一些相应的解决措施。

| Abstract: | Rangeland types and their plant resources of Gongshan Dulong and Nu Ethnic County in the Yunnan province were investigated in 2009 to improve the sustainable development of husbandry.The results of this investigation showed that the rangeland area of Gongshan Dulong and Nu Ethnic County was 181 734 ha and accounted for 26.35% of total land area,and this rangeland was identified into 5 rangeland types,including 11 group and 60 sorts.193 plant species from 45 families were identified in this survey,in which Gramineae plants with 40 species and Cyperaceae plants with 12 species accounted for 20.7% and 6.2% respectively.Among the plants,157 species were identified as forage grass,in which the forage plants with excellent palatability and forage plants with good palatability were 87 and 53,accounting for 55.4% and 33.8%,respectively;however,19 plants was unpalatable and occupied 10.8% of 157 forage plants.Based on main problems of rangeland use,including extremely uneven distribution,serious degradation in partial area,and noxious plant expansion,this study proposed some suggestions for sustainable management of rangeland resources. |
