摘要： 通过对不同土地利用类型下土壤水分空间变化进行研究,结果表明:土壤含水量与土壤容重呈负相关,相关系数为-0.095;不同土层土壤水分变化呈中等变异性,40~60 cm土壤水分变异性达0.989;不同土地利用类型下,土壤含水量差异显著(P>0.05),植物篱不种植农作物(T3)土壤含水量最高(21.25),其次为草地(T4)(20.62),而受人类活动严重干扰下的植物篱+农作物(T1)、农作物(T2)土壤含水量最低;T2田间持水量随深度增加呈递减趋势,其余利用类型土地田间持水量在0~40 cm土层呈下降规律,至40 cm附近为最低值,然后随深度进一步增加呈缓慢升高趋势。

Abstract: Through the research on spatial change of soil moisture in different land use type.The results showed that :The first one was that there was negative correlation between the volume weight of soil and the soil moistare and the correlationcoefficient was -0.095.The second one was that soil moisture change had medium variability in different soil layers.The third one was that soil moisture significantly changes(P >0.05)with different land use type.The hedgerow(T3)without crops has the highest moisture(21.25)and the moisture of grassland was second high.The soil moisture of landswith hedgerow and crops and lands only with crops was the lowest.The forth one was that the field capacity of T2 declineswith the depth decreasing.The field capacity of soils under other land use type declines between 0 and 40 cm depth andget the lowest in 40 cm depth,then it slowly decreases with the depth decreasing.

Key words: Hedgerow, Soilmoisture, Fieldcapacity
