摘要
通过对松嫩平原八市县草原草场生物学产量和生产力3年的调查研究,结果表明:松嫩平原牧草产量呈两个明显趋势,一方面是采草场和草库仑草场产量均有较大提高,另一方面由于过度放牧使放牧场产量呈下降趋势。因此,应采取必要措施使草原生产力向良性循环发展。
The grassland biological output and productive force of eight counties was studied in Song Nen plainfor three years(1990~1992).Result indieated that there were two clear tread,one was the yield ofherbage range and enclosed pasture increased gradually;the other was that yield of grazing land decreasedwith heavy grazing.The measures to make the productive forces to good cycle must be taken.
