摘要： 论文根据连续两年土壤水分的定点和观测数据,对黄土丘陵区不同土地利用类型及其结构与土壤水分的时空关系进行了分析。结果表明:①在欠水年,土地利用间土壤水分的差异显著,而在丰水年,土地利用间土壤水分的差异不显著;②在丰水年,土壤水分的年内变化只有灌木地为消耗型,间作地、果园、林地、草地、撂荒地和农地等6种土地利用类型为平衡型或增长型,欠水年所有土地利用均为消耗型;③从丰水年到欠水年,土壤水分的剖面结构类型降低型向波动型转化,波动型向增长型转化;④单一土地利用结构的土壤水分从坡顶到坡脚具有增长的趋势,而土地利用结构复杂的土壤水分沿坡面分布复杂。

关键词: 土壤水分, 土地利用类型, 土地利用结构, 黄土丘陵区

Abstract: Based on fixed and consecutive measurements of soil moisture in hilly area of loess during wet and dry years,spatio-temporal relationships between land use types and their struc-tures were analyzed.The results are as follows:(a)the effects of land use on soil moisture are sta-tistically different in dry year,but not in wet year;(b)the annual changes of soil moisture during wet year are consuming type for shrub land,and balance type and increasing type for intercrop-ping land,orchard,woodland,grassland,fallow land and cropland.However,these changes of soil moisture during dry year are consuming type for all land uses;(c)from wet year to dry year,profile types of soil moisture change from decreasing type to fluctuation type,and from fluctua-tion type to increasing type;and(d)soil moisture of single land use structure has increasing trend from hill top to bottom,but complicated distribution patterns are found for multiple land use structure along slopes.

Key words: soil moisture, land use type, land use structure, hilly area of loess
