艾比湖湿地自然保护区典型群落土壤理化性质分析

对艾比湖湿地自然保护区16个典型群落的土壤理化性质进行分析,试验结果表明：1）土壤水分的空间分布特征反映了阿齐克苏河河谷沿线西部较东部干旱的现象;土壤盐渍化现象严重,且碱化现象较明显,土壤pH值垂直分布无明显特征;有机质含量,P含量均贫乏。2）含盐量与含水量呈正相关（R=0.584）,与P含量相关性不明显（R=-0.1...

The soil physiochemical properties of typical communities in Ebinur Lake Wetlands Nature Reserve

Based on the investigated data of 40 sample plots in 16 typical communities in Ebinur Lake Wetlands Nature Reserve,we analyzed the correlation among the soil physicochemical properties by using correlation analysis;and probed the most important soil physiochemical properties that affect formation of different typical communities in Ebinur Lake wetlands nature reserve after using method of principal component analysis.The research results showed that: 1) There are great spatial differences in soil moisture content,west area is drier than east area;soil salinization is serious and alkalified is obvious,and vertical distribution of soil pH value has no obvious characteristics;the organic matter and total P content in soil are generally poor.2)There is a significant positive correlation between salt content and soil moisture content(R=0.584),while salt content is not obvious to P content(R=-0.108),indicating that there is tiny influence on ability of absorbing P from plants produced in salinization soil;organic matter has a significant positive correlation with salt content and soil moisture content,revealing that water and salt play an important role in decomposition and transformation of soil organic matter in the wetlands in arid areas.3) pH value is the most important soil physiochemical properties that affect formation of different typical communities in Ebinur Lake wetlands.
