对甘肃景泰不同种植密度的10年龄人工柽柳(Tamarix chinensis)林地,监测根周及行间土壤水分含量,并对监测资料进行量化分析。结果表明:(1)在垂直剖面上,根周土壤水分含量层次可分为蒸发层0~40 cm、活跃层40~180 cm和相对稳定层180~200 cm;行间土壤水分含量层次可分为蒸发层0~40 cm、活跃层40~120 cm、相对稳定层120~200 cm。(2)林地土壤水分主要靠天然降水补充,土壤水分储量年际变化随种植密度由高到低呈亏空-富余-亏空的变化趋势;综合考虑行距-土壤水分储量回归方程及冠积-行距回归方程,得出景泰地区合理种植密度为1 923株·hm-2。结果可为干旱区生态恢复和退耕还林提供科学依据。

Tamarix chinensis has astrong tolerance to the drought stress, salt stress, wind erosion stress, and it is widely distributed in arid-desert areas of northwest China for ecological restoration. We studied a 10-years-old cultivated T. chinensis community with different planting density, and monitored the soil moisture around the root. From the quantitative study, soil moisture near the root could be divided into 3 groups: evaporated layer (0-40 cm), active layer(40-180 cm), stable layer(180-220 cm). And the classification changed in the planting space, as evaporated layer (0-40 cm), active layer (40-120 cm), stable layer (120-200 cm). Besides, along with the planting density' increasing, the inter-annual of soil water storage will change in shape of a parabola. Our results suggested that the appropriate planting space for the studied region could be 1 923 plants per hectare.
