摘要
本文通过测定樟子松防风固沙林草地植物产量,对草本植物生物产量的季节动态及林分密度对草本植物产量的影响作了定性和定量分析。此外,还采用牧草产量法对章古台樟子松固沙林可牧资源生产潜力进行了初步评价。
On the basis of the determination of grass yield in artificial windbreak and sand-fixation Pinus sylvesrtis var. mongolica forest, the effects of seasonal change of herbage biomass yield and forest density on the herbaceous plant yield are qualitatively and quantitatively analyzed. Moreover, the pasturable resource productivity potential at artificial sand-fixation Pinus syl-veitris vur. mongolica forest in Zhanggutai region is preliminary assessed through the method of forage grass yield.
