| 摘 要： | 对章古台针叶固沙林土壤(0~300 mm)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(200~300 mm)板结严重,土壤水分状况较差,干化现象突出。

| Abstract: | 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 could 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. |
