中文摘要	2007年10月,以干旱区山麓带新疆伊犁伊宁县金山地区28个样方调查资料为基础,选用Shannon-Wiener和Simpson综合多样性指数、Margalef丰富度指数、Herlbert多样性指数(种间相遇几率PIE)以及Pielou均匀度指数和土壤电导率、土壤含水率、土壤pH、土壤全盐量以及各种盐分、土壤有机质、养分共19个土壤因子进行回归分析. 结果表明:土壤平均含水率与Pielou均匀度指数二项式回归达显著相关(P=0. 037),土壤平均pH与Shannon指数和Herlbert多样性指数的二项式回归均达显著水平(P=0.049, P=0. 044), Herlbert多样性指数和Shannon指数与0-20cm土壤的全盐量直线回归有极显著相关性(P=0.003, P =0.005),与20-40cm土壤的全盐量直线回归有显著相关性(P=0.01, P=0.04),与土壤电导率的直线回归有极显著相关性(P=0.001, P=0.001),与0-20cm和20-40cm土壤HCO-3有显著相关性(P=0.03, P=0. 015;P=0.047, P=0.05),与0-20cm Ca~(2+)表现为极显著相关(P=0.001, P=0.001)与20-40cm Ca~(2+)土壤显著相关(P=0.021, P=0.078), Shannon多样性指数与0-20cm土壤有机质含量有较显著相关性(P=0. 048).
英文摘要	Regression analysis was used to study the relationship between Shannon-Wiener, Simpson, Margalef, Herlbert (PIE), Pielou indices and 19 soil factors(soil conductivity、soil water content、soil p H、soil salt content、various kinds of salt、organic matter、nutrients) at three different soil layers in in foothill belt of arid area of Yili in Xinjiang in October in 2007. The results indicated that soil average water content was correlative to Pielou (P=0.037), Shannon and Herlbert diversities were correlative to soil pH(P=0.049, P=0.044). Herlbert and Shannon diversities were significantly correlative to 0-20 cm soil salt content (P=0.003, P=0.005), correlative to 20-40cm soil salt content (P=0.01, P=0. 04), were significantly correlative to 0-20 cm soil conductivity (P=0.001, P=0.001), correlative to 0 -20cm, 20-40cm soil HCO-3(P=0.03, P=0.015;P=0.047, P=0.05), significantly correlative to 0 -20cm soil Ca~(2+)(P=0.001, P=0.001) and correlative to 20-40cm Ca~(2+)(P=0.021, P=0.078). Shannon diversity index was correlative to 0-20 cm soil organic matter(P=0.048).
