We collected leaves of C3 plant-R, eymosa Tratt from lower altitude of Molan, 450 m above sea level, to higher altitude of Ansun, 1330 rn above sea level, in limestone areas of southwest China at November 2001, and analyzed nutrient concentrations and carbon isotope compositions.

为了研究植物营养元素的含量和δ~(13)C值随海拔而变化的相关关系，沿着海拔450 m的贵州茂兰至海拔1330 m的贵州安顺一线，采集和分析研究了C_3植物——小果蔷薇(R.cymosa Tratt)的叶片。

The water content and soil nutrient concentration are the highest near the 155-meter height of water level. The vertical distribution of vegetation spatial pattern demonstrates four belts, which respectively include Floodplain annual herb belt, Xanthium sibiricum belt, Paspalum paspaeoides belt and riparian Heights High-grass plants belt.

3受三峡库区蓄水水位变动影响下的的研究区域，表征河流生境变化的水分格局、土壤养分、植被分布均表现为明显的梯度变化，水分、土壤养分在155m附近为最高；植被空间格局呈四个带垂直分布，即从低海拔到高海拔依次为河漫滩一年生草本植物带、苍耳带、双穗雀稗带和河岸高地高草植物带。

The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

结果表明，两种氮肥处理之间以及不同家系之间各营养成分含量差异均达极显著水平；增施氮肥有利于提高秸秆的粗蛋白和粗脂肪的含量，降低酸性洗涤纤维和中性洗涤纤维的含量；两种氮水平条件下，不同家系之间秸秆各主要营养成分含量的变异性分离均符合正态分布，并存在不同程度的双向超亲分离；不同基因型的玉米对氮素的敏感性各异。
