| 摘 要： | 黄河三角洲大面积人工刺槐林出现了衰退现象,表现为树木梢头出现不同程度的枯稍。为了揭示该地区刺槐林衰退的原因,对不同退化程度刺槐林的土壤特征进行研究。结果表明:随着刺槐林退化程度的增加,土壤密度(全层)逐渐增大,土壤多项养分指标有不同程度的下降趋势,土壤含盐量随退化程度的加重逐渐增大;在不同退化程度的刺槐林分中,基本趋势是随着退化程度的加重,脲酶、多酚氧化酶、过氧化氢酶和过氧化物酶的活性呈现降低的趋势;不同退化程度刺槐林的土壤中微生物总量随退化程度的加重而减少。

| Abstract: | The degradation of Robinia pseudoacacia plantation on Yellow River Delta took place in large area and the shoots of R.pseudoacacia trees were dried-up with different degree.In order to reveal the degradation causes of R.pseudoacacia plantation,soil characteristics of R.pseudoacacia plantation were studied.The results showed that soil density increased gradually with the increasing of the degradation degree of R.pseudoacacia plantation.With increasing of degradation degree of R.pseudoacacia plantation,many i... |
