摘要：为了解不同植被恢复模式对土壤理化性质的影响,对定西市巉口林业试验场3种不同植被恢复模式(云杉林、杨树林、混交林)和不同恢复阶段的土壤主要理化性质进行研究,结果表明:3种不同植被类型的土壤含水量表现为混交林>杨树林>云杉林;有机质、总氮、总磷含量为混交林>云杉林>杨树林;p H值为杨树林>云杉林>混交林。云杉林和混交林的土壤含水量随恢复时间的延长呈先上升后降低趋势,恢复30 a的土壤含水量最高;杨树林土壤含水量随恢复时间的延长逐渐上升。混交林土壤有机质、总氮、总磷含量在前15 a明显增加,15 a后基本趋于稳定;云杉林的三者含量在前30 a逐渐上升,30 a后下降;杨树林土壤有机质、总氮、总磷含量均略有下降。土壤p H值随恢复时间的延长均略呈下降趋势。巉口林场的杨树林土壤有机质、总氮、总磷含量均处于最低水平,且随恢复时间的延长逐渐降低;混交林具有较强的蓄水保水能力,大大改善了土壤环境质量,较适合该区域生态恢复重建。
In order to understand the effect of different vegetation restoration patterns on soil physical and chemical properties,the main soil physical and chemical properties （water content,organic matter,total nitrogen,total phosphorus and pH value）of three kinds of different vegetation restoration patterns （spruce forest,poplar forest and mixed forest）and different recovery stages of Dingxi Chankou forestry experi-mental farm from October 2011 to September 2012 were studied. The results show that soil water content shows the succession of mixed forest〉 poplar forest 〉 spruce forest,the succession of organic matter,total nitrogen and total phosphorus content is mixed forest 〉 spruce forest〉 poplar forest,but pH value shows the succession of poplar forest 〉 spruce forest 〉 mixed forest. The soil water content of spruce forest and mixed forest shows the trend of first increasing and then decreasing with prolonging of restoration years,the maximum value of soil water content appears in 30a forest,however,that of poplar forest gradually increases. The organic matter,total nitrogen and total phosphorus con-tent of mixed forest increases obviously in the first 15a,that tends to be stable after 15a,and the spruce forest increases gradually in the first 30a,showing a downward trend after 30a,but them of poplar forest shows a slightly decreasing trend. The soil pH value of three kinds of vegetation restoration patterns all shows a slightly decreasing trend with prolonging of restoration years. The results indicate the soil organic matter,total nitrogen and total phosphorus of poplar forest are at the lowest level in Dingxi Chankou forestry experimental farm,and decrease gradually with prolonging of restoration years,however,the mixed forest has strong capacity of water storage and improves greatly the soil en-vironmental quality,that is suitable for the ecological restoration in the region.
