中文摘要	为探讨土地灌溉对土壤碳及理化性质的影响,通过土柱法定位模拟研究灌溉灰漠土和原生灰漠土分别种植春小麦和水稻下土壤有机碳和无机碳及理化性质的分层变化特征。结果表明:一个生长季后土体随深度的增加,灌溉灰漠土有机碳的含量表现为先减少后增加,变化范围为-1. 80?1.56 g/kg,而原生灰漠土有机碳变化表现为:减少一增加一减少,变化范围为-0.39~0. 40 g/kg;灌溉灰漠土和原生灰漠土土体无机碳的含量表现为整体减少部分土层增加,各土层变化范围分别为-1. 10~0.45 g/kg,-1.3?1.02 g/kg;灌溉灰漠土 pH值变化范围为-0.70?0.49,呈M型,原生灰漠土 pH变化规律不明显;电导率值均降低,原生灰漠土变化强烈,而灌溉灰漠土相对稳定。
英文摘要	In order to explore the effects of irrigation on soil organic/inorganic carbon and physicochemical properties,a soil column leaching experiment was carried out to simulate irrigation. The different soil with different crops (spring wheat and rice) were chose to explore the variation of soil organic/inorganic carbon and physicochemical properties. The leaching experimental with a growing season showed that with the increase of depth, the soil organic carbon content of irrigation gray desert was increased after first decreased, the values’ range was -1. 80?1. 56 g/kg. Soil organic carbon of native gray desert soil changed as follows:decreased-increased-decreased, the values’range was 0. 39?0. 40 g/kg. The soil inorganic carbon of irrigation gray desert soil and native gray desert reduced, layer variation was 1. 10?0. 45 g/kg, 1. 3?1. 02 g/kg. Soil pH values of irrigation gray desert soil varied from 0. 70 to 0. 49,showed as M"type, however it of native gray desert soil variation was not obvious. Soil conductivity values before and after leaching were downtrend, native gray desert soil changed stronger, while irrigation gray desert soil were relatively stable.
