| 摘 要： | 通过对九龙甸水源区幼年桉树人工林和成年桉树人工林土壤特性的测定,以云南松天然林作为对比,结果表明,该水源区3种林分土壤容重都随着土壤深度的增大而逐渐增大,成年桉树人工林的土壤容重最大,幼年桉树人工林次之,云南松天然林最小;幼年桉树人工林和成年桉树人工林土壤有机质含量都明显少于云南松天然林;云南松天然林的水源涵养能力最好,成年桉树人工林最差,种植桉树人工林使得水源区水源涵养能力降低。

| Abstract: | By determining soil characteristics of youth and adult artificial eucalyptus in Jiulongdian Reservoir, with Pinus yunnanensis as the control, it was found that the soil bulk density of the three kinds of forest in Jiulongdian Reservoir are increase along with the increase of soil depth. The soil adult bulk density of euealyptu forest is the largest, youth eucalyptus take second place, Pinus yunnanensis forest is the mini- mum ; The soil organic matter content of soil organic matter content were significantly less than the Pinns yunnanensis forest; The water conser- vation capacity of the Pinns yunnanensis is the best, adult eucalyptus is the worst. Planting euealypt could reduce the water conservation te- nacity of catchment area. |
