摘要:
根据长安地区苹果林地及曲江地区梧桐林地和杨树林地土壤含水量测定，研究了0-6 m土壤含水量的变化和土壤干层的恢复。结果表明，在丰水年之后长安地区人工林地土壤含水量与正常年份土壤含水量有明显不同，12 a苹果林地2-4 m土层含水量平均11.77%，14 a苹果林地平均15.27%；曲江地区丰水年之后12 a杨树林地2-4 m平均含水量18.53%，14 a梧桐林地2-4 m平均含水量17.24%，干层完全消失。这表明在降水量增加的条件下，黄土高原南部土壤干层中的水分完全可以恢复。长安与曲江地区丰水年之后经过约2年半的时间，人工林土层水分恢复深度可达到6 m左右。不同树种含水量差异较大，苹果林地干层带水分恢复比梧桐、杨树林明显低。
Abstract:
According to the soil moisture content determination under the apple forest land in Chang’an and under the Chinese parasol tree forest land and the poplar tree forest land in Qujiang, the soil moisture content of 0-6 m and the restoration of the soil-dried layer has been studied. The results indicate, after the abundant water year in Chang’an under artificial forest land, the soil moisture content is more obviously different than the normal year, under 12 ages apples forest land in 2-4 m depth scope the soil layer water content is 11.77%, and 15.27% in 14 ages apples forest land; After the abundant water year in Qujiang, the soil layer water content in 2-4 m depth scope, under 12 ages poplar trees forest land is equal to 18.53%, under 14 ages Chinese parasol trees forest land is equal to 17.24%, the soil-dried layer obviously vanished. This indicates under the condition of increases in the precipitation, in south of the loess plateau the moisture content of the soil-dried layer is possible to restore completely. After 2.5 years in abundant water year in Qujiang and Chang’an under the planted forest land the restored depth of soil layer moisture content is possible to achieve 6 m approximately. Difference of different tree seed water content is big, under the apple forest land the dried-belt moisture content to restore is obviously lower than under the Chinese parasol tree and the poplar tree forest land.
