摘要:
 以延河流域69个主要物种为研究对象，测定其植株高（height,H）、种子干重（seed matter,SM）和比叶面积（specific leaf area,SLA）3个功能性状，探讨leaf-height-seed（LHS）策略在延河流域的适用性、主要植物的功能型划分及各功能型植物在延河流域的分布。结果表明：1）LHS策略能很好地适用于延河流域，且通过该策略将69个物种分成了5个植物功能型。功能型Ⅰ植物属于干扰型和竞争型，适合生长于高干扰、高竞争和低压力的环境中；功能型Ⅱ植物属于杂草型，适合生长于高干扰、低竞争和低压力环境；功能型Ⅲ植物属于耐胁迫型，适合生长在高胁迫和高竞争的环境中；功能型Ⅳ植物属于竞争型，适合生长于高竞争和低压力的环境中；功能型Ⅴ植物属于竞争型和杂草型，适合生长于低胁迫和高竞争环境。2）延河流域具有较明显的环境梯度变化，各个功能型植物在流域中表现出一定的分布特点，从南向北（森林带—森林草原带—草原带）植物功能型依次分布为植物功能型Ⅳ（植物功能型Ⅰ为伴生种）→植物功能型Ⅲ和植物功能型Ⅳ（植物功能型Ⅰ、Ⅱ、Ⅴ为伴生种）→植物功能型Ⅲ（植物功能型Ⅰ为伴生种）。
Abstract:
 The paper focused on 69 dominant plants in the stable natural plant community in the Yanhe River basin,three traits of each sample were measured,including plant height（H）,seed mass（SM），specific leaf area（SLA）,to test the leaf-height-seed (LHS) strategy applicability in Yanhe River basin,to classify plant functional types (PFTs) of each species and the distribution of each functional plant functional types.The results showed that:1) the LHS strategy could be well applied in the Yanhe River basin,and 69 dominant plants were divided into 5 kinds of plant functional types.PFT Ⅰ plant belonged to the interference and competition type which was suitable for growth in high interference,high competition and low stress environment.PFT Ⅱ plant belonged to the weed type which was suitable for growing in high interference,low stress and low competition environment.PFT Ⅲ plant belonged to the stress resistant type,which was suitable for growing in high stress and high competition environment.PFT Ⅳ plant belonged to the competitive type which was suitable for high competition and low pressure environment.PFT Ⅴ plant was a competitive and weed type which was suitable for growing in low stress and high competition environment.2) Environmental gradients changed obviously in the Yanhe River basin.Various plant functional types also showed different distribution characteristics.In the southern part of the basin (forest belt),PFT Ⅳ was dominant and PFT Ⅰ was associated species.In the central part of the basin (forest steppe belt),PFT Ⅲ and PFT Ⅳ were dominant,PFT Ⅰ,PFT Ⅱ and PFT Ⅴ were associated species.In the northern part of the basin (steppe belt),PFT Ⅲ was dominant and PFT Ⅰ was associated species.
