| 摘 要： | 人工营造的旱柳与旱柳混交林是汾河上游河岸带面积较大的代表性植被群落,以河漫滩为对照,就这2种植被类型对土壤粒级组成与土壤含水量的影响进行了研究.结果表明:在2种植被类型的土壤中,石砾与砂粒含量分别低于对照17.2%与9.4%,粉粒、黏粒与物理性黏粒的含量高于对照3.4%～22.5%,大于0.05mm与小于0.005mm土壤颗粒的含量与河漫滩存在显著差异(P<0.05);与河漫滩相比,2个林分显著地提高了土壤饱和持水量、毛管持水量、田间持水量与自然含水量(P<0.05), 提高幅度为3.7%～10.4%;土壤含水量与石砾、砂粒含量成负相关,而与粉粒、黏粒和物理性黏粒含量成正相关. |

| Abstract: | Salix matsudana plantation and Salix matsudana-Hippophae rhamnoides mixed plantation occupied a large area in the riparian zone of the upstream of Fenhe River.The differences in soil particle composition and soil water content for different vegetation types were studied in comparison with the floodplain.Results indicated that contents of gravel and sand in the soil in the two plantations decreased by 17.2 percent and 9.4 percent respectively,while contents of soil silt,clay and physical clay particle increa... |
