摘要
竹林土壤肥力是竹林发展与规划的重要依据。本研究以建瓯市毛竹林地土壤为对象,通过野外系统采样,选取全氮、碱解氮、有机质等9个土壤肥力指标,在GIS软件的支持下,利用模糊数学综合评价法进行竹林土壤肥力评价。结果表明,建瓯市毛竹林地土壤肥力总体属于中上等水平,土壤中全氮和有机质含量较高,有效磷和速效钾含量较低成为毛竹林地土壤肥力的主要限制因素。土壤肥力的空间分布呈现出西南和东北部较高,中部较低的特点。本研究结果可以为当地今后的生产实践及发展规划提供参考,也可为其他地区提供借鉴。
Soil fertility is important for the bamboo developmen t and planning. In this study, the Phyllostachys pubescens forest in Jian ’ ou was selected for the assessment of soil fertility. Nine soil properties were selected as the indicators of soil fertility and then they were evaluated by using the method of fuzzy comprehensive evaluation combined with GIS software. The results showed that the soil fertility in Phyllostachys pubescens forests belonged to the middle and high levels. The contents of soil total nitrogen and organic matter were high, but those of available phosphorus and available potassium were low, which became the main limiting factors of soil fertility in bamboo forests. The soil fertility level was higher in the southwest and northeast and lower in the middle region. The results obtained in this study could be useful for the local bamboo production and development and provide effective references in the other region.
