First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by Brewer, Durbin, Sampford , Des Raj , Murthy , Rao-Hartley-Cochran. Then, at the basis of Rao and Bayless's study , we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super-populations, and compare the stabilities of estimators of the methods that given above.

The results showed that elevated CO2 increased the R/S ratio and the dry mass of both coarse and fine roots, indicating that the seedlings under elevated CO2 allocated more biomass to their belowground part. Compared with control, elevated CO2 increased the contents of reducing sugar, sucrose, and total soluble sugar in coarse roots significantly, but had less effect on those in fine roots. Elevated CO2 increased the contents of starch and total non-structural carbohydrate both in coarse roots and in fine roots. Under elevated CO2, the carbon content in coarse and fine roots had an unsignificant increasing trend, while the nitrogen content decreased significantly, which resulted in an increase of C/N ratio.

结果表明：CO2浓度升高使红桦幼苗粗根和细根的干质量增加，同时根／冠值显著升高，表明CO2浓度升高使红桦幼苗生物量向根系的分配增加；与对照相比，粗根的还原糖、蔗糖和总可溶性糖含量显著增加，而在细根中没有显著变化；粗根、细根的淀粉和总的非结构性碳水化合物含量显著增加；CO2浓度升高下粗根和细根的碳含量有升高的趋势但未达到显著水平，同时氮含量降低，碳／氮值升高；氮的吸收量在粗根和细根中均无显著变化。
