中文摘要	以博斯腾湖西岸湖滨绿洲芦苇地为研究区,分析不同长势芦苇地土壤特征,建立土壤主要特征因子与芦苇长势之间的回归模型。结果表明:芦苇地土壤盐分质量分数与电导率之间存在显著正相关,相关系数为0.97,土壤氧化还原电位(ORP)与pH间存在极显著负相关,相关系数为0.98;土壤盐分质量分数和电导率具有明显表聚现象,在0~10 cm土层中,盐分质量分数占0~50 cm土壤盐分总量的58.08%,电导率占0~50 cm总电导率的45.21%;土壤盐分质量分数和pH是影响芦苇长势的主要特征因子, 芦苇株高和土壤盐分质量分数之间的回归方程为H=0.01S~3-0.27S~2+1.15S-1.19,R~2=0.88,芦苇生长最适盐分质量分数在3.80~4.40 g/kg;芦苇数量与土壤pH间的回归方程为M=-196.71pH+1 741.80,R~2=0.92,芦苇生长最适pH为7.80(F>95%)。
英文摘要	Taking the west bank of Boston lakeside oasis as the study area, we analyzed the characteristic of the different soil of growth Phragmites australis land, eventually established regression model between soil characteristic factor and Phragmites australis growth.The results showed that there was significant positive correlation between salt mass fraction and conductivity, the correlation coefficient was 0.97, there was significant negative correlation between soil oxidation reduction potential(ORP)and pH, the correlation coefficient was -0.98 (P>0.01); salt mass fraction and conductivity had obvious table gathered phenomenon in 0-10 cm soil layer, the salt mass fraction accounted for 58.08% of the total salt mass fractionsalt from 0-50 cm, the conductivity accounted for 45.21% of the total conductivity from 0-50 cm;the salt mass fraction and pH were major nature factors for Phragmites australis growth, the regression equation between salt mass fraction and vegetation mass was H=0.01S~3-0.27S~2+1.15S-1.19,R~2=0.88, the optimal salt mass fraction for Phragmites australis height between 3.80-4.40 g/kg; the regression equation between Phragmites australis number and soil pH was M=-196.71 pH+1 741.80,R~2=0.92, the optimal pH was 7.80(F>95%).
