摘　　要：为探究冀北山地四种典型落叶松林分的生态功能,以木兰围场国有林场管理局北沟林场内落叶松纯林和落桦混交林、落阔混交林和杉落针阔混交林4种不同落叶松林分类型为研究对象,通过对生物量的计算与持水能力的测定,测定其不同林分固碳释氧、净化空气和涵养水源等功能。结果表明:研究区不同落叶松林分内同功能效益指数均显示林分D最高,林分B,C次之,林分A最低,从而得出,林分D是四种林分中最优的,生态功能是最强大的。To explore the ecological functions of four typical larch stands in mountain of northern Hebei, the four different larch forest types such as larch, mixture of larch and birch, coniferous - broadleaved mixed forest and mixture of larch andconiferous fir were chosen as the samples. The clean air and water conserva- tion functions were investigated through the calculation of biomass and water-holding capacity determination, and estimation of carbon sequestration and oxygen release in different stands. The results showed that function efficiency index of stand D was the highest, followed by stand B and stand C, the least one occurred in stand A, therefore, stand D is optimal and its ecological function is the most powerful among the four stands.
