Rangeland resource situation and use planning of Gongshan County in Yunnan Province
摘要
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.关键词
