| 摘 要： | 桉树生长快,经济价值高,现成为世界各国引种和推广的材种。但因其速生性消耗大量水分,因而有人对其在中国推广种植持相反意见。本试验通过对安宁河流域人工桉树林土壤容重、土壤孔隙度、土壤含水量、蒸腾速率进行定期测定,研究其水分特性。结果表明该人工桉树林保持土壤水分能力较低,指出在人工桉树林发展中确实出现了一些经营和技术上的问题,因而必须科学规划,合理经营。

| Abstract: | Eucalyptus is planted widely for its growing fast and high economical value. On the other hand, some people argued against its planting for the high water consuming. In this experiment, the soil bulk density, soil porosity, soil water content and evaporation were determined to study the Eucalyptus stand water features. The results showed that the Eucalyptus stand had low water holding capacity, some managements were not suitable for some Eucalyptus stands＇ development. So scientific plan and reasonable management are needed to improve the Eucalyptus stand to be an ecological man-made forest in Anning river area. |
