英文摘要
The springwheat–shelterbelt–maize agroforestry ecosystemis one of themost common land use patterns occurring
in oasis agriculture in the arid zones of northwest China. Soil water interactions were hypothesized to exist
between adjacent land use types, and that these interactions could be analyzed by using the soil water content
(SWC) measured at the most time-stable locations (MTSLs) under each land use type. Objectives of this study
were to (1) identify the MTSLs for the different soil layers under each land use type and (2) to investigate the
soil water relations between adjacent land use types using the SWC measured at the identified MTSLs. The
SWC was measured in 2012 and 2013 at 10-cm depth intervals within 0–260 cm soil profiles at 36 locations
along three transects that passed through spring wheat, shelterbelt, andmaize subplots. A time-stability analysis
ofSWCwas used to identify theMTSLs in the four different soil layers under each of the three land use types. The
results indicated that temporal variations in soil water in the same soil layer among the three land use types
tended to have similar patterns. The SWC of the different soil layers undermaize exhibited the highest temporal
stability among the three land use types. TheSWCmeasured at theMTSLs identified for each soil layer under each
land use typewas proven to represent their meanSWC. Correlation analyses of the SWCs measured at theMTSLs
between two land use types indicated that soilwater relations occurred between adjacent land use types but not
between those that were non-adjacent land use types by the correlation analyses of the SWCs measured at the
MTSLs between two land use types. In the upper soil layer (0–200 cm), soilwater relations weremainly affected
by shelterbelt rootwater uptake fromthe adjacent cropland into which the tree roots had extended. In the lower
soil layer (200–260 cm), the soil water relations among the three land use types were due to groundwater recharge,
which was a result of crop irrigation that had raised the water table to a level at which it could replenish
this soil layer.
