摘  要:
对兰州北山区4个不同造林年限(4、7、10、13年)侧柏人工林地表层土壤水分性质进行观测研究,结果表明:不同造林年限的侧柏人工林地涵养水源量存在较大差异,13、10、7、4年生侧柏林地水源涵养量比无造林荒山地分别增加201、268、251和208t/hm2;土壤最大持水量、毛管持水量、田间持水量和最佳含水量随林龄的增大而增加,其大小均是13年生侧柏林地最大,无造林荒山地最小;0~30cm层土壤水分有效性在4年生林地表现为中效水,其他林地大致都为难效水;与无造林荒山地相比,不同造林年限的侧柏人工林地土壤持水量均有一定程度增加。说明侧柏人工林能够改善土壤表层水分状况。

摘  要:
The measurements of soil surface moisture characteristics under Platycladus orientalis plantations with 4 different afforestation ages (4, 7, 10 and 13 years) were studied in northern mountain region of Lanhzou. The results showed that: The water conservation contents of Platycladus orientalis forestland varied significantly in different stand ages. The water conservation contents of 4 different afforestation ages increased by 201、268、251 and 208 t/hm2 than that of slope wasteland respectively. Maximum moisture capacity, capillary water capacity, field water capacity and optimal-water-content all increased with the afforestation age. Soil water of 0 ~ 30 cm layer in 4 years of forestland was moderate available, but was hard available for other forestlands. Compared with the wasted land, to some degree, soil moisture content of different plantation stages all increased, and it proved that Platycladus orientalis plantations could improve soil surface water condition.
