摘要
对黑龙江大兴安岭地区现有3个草地资源的类别、9种植被类型做了简述,对草地资源现状及草地利用率做了分析。结果显示:大兴安岭林区鲜草产量达9t/hm^2,全区干草年产量为300×10^4t,目前,牧草利用率20%左右,利用率较低。应该对现有草地资源进行科学管理,合理开发和利用,并提出针对性的保护措施,使林区草原发挥最大效能,达到永续利用。
The present situation of grassland resources and utilization rate of grassland were analyzed by describing 3 categories of grassland resources and 9 vegetation types in Daxing'anling of Heilongjiang Province.The results showed that the yield of fresh grass was 9t/hm^2,the annual yield of hay was 300×10^4t,the utilization rate of forage was about 20%,and the utilization rate is low.The existing grassland resources should be scientifically managed,reasonably exploited and utilized,and specific protection measures should be put forward so as to maximize the effectiveness of grassland in forest areas and achieve sustainable utilization.
