- 摘要:
- 通过河北雾灵山5种人工纯林的土壤养分分析，研究了不同林分类型对土壤pH值、有机质、全量养分和速效养分的变化，并对不同土壤养分进行了主成分分析。结果表明：5种不同林分类型的土壤pH值均为弱酸性，其变化范围为4.61～6.31；不同土层土壤有机质表现为：表层（0—10 cm）> 中层（10—20 cm）> 下层（20—40 cm），有机质均值在2.53～9.60 g/kg之间；土壤全磷含量均值为0.20～0.70 g/kg；土壤全氮含量均值为2.38～3.45 g/kg；土壤速效钾含量均值为67.54～169.88 mg/kg；土壤速效磷含量均值在0.84～6.84 mg/kg之间；土壤碱解氮含量均值在65.68～147.88 mg/kg之间；不同林分类型土壤养分综合效应评价，白桦纯林最大，为1.122；落叶松纯林最小，为-0.819。综合来看，随土层厚度增加土壤养分含量减少；阔叶林土壤养分含量大于针叶林。
- Abstract:
- This paper measured soil nutrients in 5 planted pure forests of in Wuling Mountains of Hebei. The effects of different forest types on soil pH, organic matter, nutrients and available nutrients were studied, and soil nutrients were analyzed by principal component analysis. The results showed that soil pH values in 5 different kinds of forests were weak acidity, the range was 4.61～6.31; soil organic matter in different layers decreased in the order of 0—10 cm > 10—20 cm > 20—40 cm, means of organic matter are 2.53～9.60 g/kg; soil total phosphorus contents were 0.20～0.70 g/kg; mean total soil nitrogen contents are 2.38～3.45 g/kg; soil available potassium contents are 67.54～169.88 mg/kg; soil available phosphorus contents are 0.84～6.84 mg/kg; soil alkali solution nitrogen contents are 65.68～147.88 mg/kg. Evaluation of soil nutrients in different forest types of comprehensive effect of Betula pure forest is maximum, 1.122; Larix pure forest is minimum, -0.819. In general, soil nutrient contents decrease with the increase of soil depth. Soil nutrient concentrations are in coniferous forests than those in broad-leaved forests.
