草地牧草产量草地牧草产量forage yields of grasslandeoodi mueaoehanliang草地牧草产量(forage yields of gnlssland)某一时间单位面积草地上所存在的可饲用的植物重量。这是畜牧业经济产量，有别于生态学所研究的植被生产量。畜牧业生产需要的不是草地植物群落和植物种群的全部有机质生产量(生态学的第一性生产概念)，而是其中有饲用价值的那部分产量，可用来放牧或割草饲养家畜，进而能转化成畜产品。通常是植物群落和种群的地上部分，或者是植物地上部分的某些器官(叶、茎、花、果实)。薰测产四川红原(《中国草场资源图集》)草地牧草产量的内容:①牧草现存量是在单位时间内，在单位面积上，草地植物群落和植物种群所生产的有饲用价值的有机物质的数量。两个时期之间的牧草产量的变化，为这段时间的生长量，表示单位为克(干重)/平方米或千克(干重)/公顷，同时必须指明时间，如某月某日，几天时间内的牧草生长量为xx克(干重)/平方米，某月或某季或年的牧草生长量为xx克(干重)/平方米或xx千克(干重)/公顷。②牧草生物量是指单位面积上草地植物群落和植物种群全部有饲用价值的有机物质的数量。牧草生物量的表示单位为克(干重)/平方米或千克(干重)/公顷;它不同于牧草现存量，没有时间度量的概念，只有这个时期(tl)的生物量，或那个时期(t:)的生物量之分，而无一年内的生物量或一个月内的生物量的涵义。它具有单位面积草地上牧草贮藏量的涵义。例如，春季草地调查时，某草地类型牧草生物量则是去年的牧草保存量和当年再生的牧草生长量之和。
