中文摘要	以内蒙古农牧交错带柠条锦鸡儿(Caragana korshinskii Kom.)人工林为研究对象,在秋季对其根系分布特征及土壤水分采用四分之一圆法分层采样分析,研究了柠条锦鸡儿根系生物量与土壤含水率空间分布规律。结果表明: ①柠条锦鸡儿根系呈浅层化分布,根系主要集中在0 ~ 60 cm土层; ②根系生物量与土壤水分的空间分布规律基本一致,且根系分布与同空间内土壤水分存在正相关关系,均表现为随着土层深度的增加而逐渐减少; ③在垂直、水平方向,各实验地柠条锦鸡儿根系生物量与土壤含水率均呈显著相关,构建根系生物量与土壤含水率的经验模型,验证发现该模型可以很好地说明二者的关系。研究结果旨在为干旱区人工柠条林的栽植管理及植被恢复提供理论依据。
英文摘要	This paper choose Caragana korshinskii Kom. plantation as the study object,analyzed the root system distribution characteristics and soil water content in autumn. And quarter circle method was used to sample every layer to study the spatial distribution pattern of root system biomass and soil water content. The results showed that ①The root system was mainly concentrated on the shallow layer(0 ~ 60 cm soil layer); ②the root system biomass spatial distribution was consistent with that of the soil water content,and they were positively correlated. Along with soil layer depth increasing,root system biomass and soil moisture content gradually decreased; ③root system biomass was significantly related with soil water content both in vertical and horizontal direction. Empirical model of root system biomass and soil water content was established to validate the relationship between them,and the result was good. All results were aiming to provide theoretical basis for Caragana korshinskii Kom management and vegetation restoration in arid area.
