摘 要:利用遥感信息,GIS技术分析了东北土地资源,结合统计资料,研究了东北草食牲畜发展的关联要素,并根据粗饲料的主体来源和饲养方式,总结了草食牲畜生产模式。根据植被类型和草地、农田、林地的比例,对草食牲畜生产模式进行了区划。东北草地资源匮乏,草食牲畜发展能力饱和,草食畜牧业的发展空间和潜力在农区和林区。草地畜牧业区,发展草食牲畜的潜力在于发展高产饲料作物,并提高饲养效率;秸秆畜牧业区、草地-秸秆畜牧业区、林地-秸秆畜牧业区,草食牲畜发展的潜力是充分利用粗饲料资源,发展数量型畜牧业,在此基础上提高出生率、生长率、出栏率、产肉率,发展效益型草食畜牧业。land resources and the factors associated with the development of herbivorous animals in northeast China using remote sensing were analyzed,GIS technical and statistical data,and the models of herbivorous animals according to roughage source and raising pattern were summed up.The livestock production was divided into five regions based on vegetation type and the proportion of grassland,farmland,woodland.The grassland resource is scarce and the development capacity for livestock has been saturated in northeast China,the potential for livestock production should be in farming and forest regions.Developing high-yielding fodder crops,and improving breeding efficiency are very potential for development of herbivorous animals in grassland-animal husbandry areas;making full use of fodder resources and developing quantitative animal husbandry are very promising in stover-animal husbandry areas,grassland-stover animal husbandry areas,woodland-stover animal husbandry areas.In addition,increasing the birth rate,growth rate,marketing rate and meat production rate is also very important for developing benefit based livestock production.
