chinois. 采用WinRHIZO 2009根系分析系统获取33种内蒙古草地常见丛生型植物的根系参数,通过数据分析,得到如下结论：1、根总表面积和根分叉数是影响丛生型植物根系构型的关键因素。2、在草地丛生型植物的各根系参数中,根系总根长与总表面积、根尖数、分叉数相关性极显著;总根表面积与根尖数、分叉数、平均直径相关性极显著;根系总体积与总表面积、平均直径相关性极显著;根尖数与分叉数相关性极显著。3、对于特定根系构型的植物来说,影响根系构型的主要因素是相对稳定的。

The results showed that： 1. Roots gross area and root fureation number are the key factors influencing the root ar- chitecture of cespitose plants ; 2. Among the root parameters of eespitose plants in the grassland, the total root length has great correla- tion signiflcanee with total root surface area/root tip numbers and fureation numbers; root total surface area has great correlation signifi- cance with root tips number/fureation number and average diameters; total root volume has great correlation significance with total sur- face area and average diameters ; root tip number has great correlation significance with furcation numbers. 3. The main factors influen- cing root architecture are relatively stable for the plants with specific root architectures.
