北方土石山区不同植被恢复模式土壤酶活性研究

Study on Soil Enzyme Activities under Different Vegetation Restoration Patterns in Northern Earth-Rocky Mountainous Area

以北方土石山区不同植被恢复模式为研究对象,测定并分析不同植被恢复的土壤理化性质与土壤酶活性的分布规律及其相互关系。结果表明:不同植被恢复均使土壤酶活性明显提高,但不同植被对土壤酶活性的影响不同;土壤酶活性与土壤环境因子的相关性不完全一致,与土壤养分因子呈正相关关系,与土壤pH值呈负相关关系。

Taking different vegetation restoration patterns in northern earth-rocky mountainous area as the research objects,we tested the soil physical and chemical properties and soil enzyme activities in different vegetation restoration patterns, and analyzed their distribution and correlation. The results showed that soil enzyme activities significantly increased under different vegetation restoration patterns, but the effects of different vegetation on soil enzyme activities were different. The soil enzyme activity is not completely correlated with soil environmental factors, but is positively correlated with soil nutrient factors and negatively correlated with soil pH value.
