摘要/Abstract

摘要： 为了解土壤水分对中国沙棘稳定性及生产力的影响,对毛乌素沙地平地与洼地人工林的相应特征进行比较分析,以期为毛乌素沙地造林设计与立地选择提供参考依据。结果表明:洼地土壤的含水率、全P及全K含量均显著高于平地,但土壤含水率对种群特征的形成起着主导作用;洼地的树高生长量、林分生产力、子株数量显著高于平地,且其种群年龄结构属于增长型(或稳定型),而平地的属于衰退型。由此可见:林分生产力和种群稳定性具有良好的一致性,土壤含水率高则洼地林分生产力高、种群稳定性强,土壤含水率低则林分生产力低、种群稳定性弱。

关键词: 中国沙棘, 林分生产力, 种群稳定性, 土壤含水率, 种群结构, 生长格局

Abstract: In order to know the impact of soil moisture on the stability and productivity,the plantations located in flatland and low-lying land in Maowusu sandland were selected to do comparative analysis on corresponding characteristics with a view to providing reference for the Maowusu Sandland afforestation design and site selection.The results show that the soil moisture content,total phosphorus and total kalium content of low-lying land were all significantly higher than flatland,but the soil moisture content played a dominant role in the formation of the characteristics of the plantation;the tree height growth,forestry productivity and ramet number of low-lying land were significantly higher than flatland,and its plantation age structure belongs to a growing(or stable) one,but the flatland belongs to declining type.Thus,forestry productivity and plantation stability have good consistency,as the soil moisture contentis higher,the forestry productivity and plantation stability of low-lying land become better,as the soil moisture content is lower,the forestry productivity and plantation stability of flatland become worse.

Key words: Hippophae rhamnoides subsp.sinensis, forestry productivity, population stability, soil moisture content, population structure, growth pattern
