摘要
对章古台针叶固沙林土壤(0~300mm)结构与湿度状况调查结果显示,固沙林营造初期对沙地土壤有改良作用,随林龄增大林地土壤出现板结状况并呈加重趋势;固沙林深层土壤(200~300mm)板结严重,土壤水分状况较差,干化现象突出。
Based on survey about status of soil structure and soil moisture(0 -300 mm) of the coniferous sand-fixation plantation in Zhanggutai, results showed that sand-fixation forest coald meliorate sandy soil at first, however along with aggrandizing of age of stand timbered-soil had been hardened gradually. Deep soil of the sand-fixation forest (200 - 300 mm) hardened badly, soil moisture status was worse and soil desiccated obviously.
