| 摘 要： | 较系统地论述了嫩江流域中下游地区小黑杨、樟子松林分的水分生产率,结果表明:小黑杨林分的水分生产率为1.113,较全国农业平均水分生产率(0.8)相对提高39.13%;樟子松林分的水分生产率为1.441,比小黑杨林分的水分生产率高29.47%,说明樟子松林分是嫩江中下游地区较好的抗旱节水型林分,应在该地区适当增加樟子松林分的比例。

| Abstract: | Water Productivity of Populus simonii×nigra and Pinus sylvestris var.mongolica stand in Middle and Lower Reaches of Nenjiang River was discussed systematically.The results showed that water productivity of Populus simonii×nigra was 1.113 and increased 39.13% compared with the national mean agricultural water productivity.The water productivity of Pinus sylvestris var.mongolica was 1.441 and was 29.47% higher than Populus simonii×nigra.It showed that Pinus sylvestris var.mongolica stand was a kind of better drought-resistant and water-saving stand.The ratio of Pinus sylvestris var.mongolica stand should be added properly. |
