摘要
北海道奶牛业从20世纪50年代开始快速发展,奶农户数减少的同时经营规模不断扩大。但是奶牛饲养头数增加与土地规模扩大之间没能保持相应的良好平衡关系。所产生的家畜粪尿量加重了环境负担。本文阐明北海道奶牛业经营规模扩大过程与土地利用方式之间持有什么样的相互依存关系来展开,并从土地利用角度进一步研究了奶牛生产粪尿产生与土地利用之间的关系。
The dairy farming in Hokkaido has beeing developed rapidly since 50's in twertieth century ,the scale of daing farm has beeing extended constantly while the family number of dairy farmer is decreased. However,the balance relationship between the increase of dairy cow number and extension of land area was not kept well. The environmental burden was became heavier due to cow's faeces and urine.
