摘要: 基于2023年8—9月在伊犁河谷布点调查的119个土壤剖面,比较了不同土壤类型(土纲)、不同土地利用类型之间0~30 cm与0~120 cm土壤储水量的差异,用多元线性回归法分析了伊犁河谷土壤储水量的主要影响因素。结果表明,就土壤类型而言,0~120 cm土壤储水量表现为半水成土(323 mm)>半淋溶土(213 mm)>钙层土(193 mm)>高山土(161 mm)>干旱土(108 mm),而各土地利用类型0~120 cm土壤储水量表现为耕地(266 mm)>林地(199 mm)>园地(184 mm)>草地(153 mm)。伊犁河谷0~120 cm土壤平均储水量为201 mm,即9.56×109 m3。土壤容重、降雨量、蒸散发量、归一化植被指数(NDVI)、高程对土壤储水量均有显著影响,砂粒含量与干燥度对0~30 cm土壤储水量产生影响,而坡度、剖面曲率显著影响0~120 cm土壤储水量。

Abstract: Based on 119 soil profiles surveyed in Ili River Valley from August to September 2023, the differences of soil water storage in 0-30 cm and 0-120 cm soil layers between different soil types and different land use patterns were compared, and the main influencing factors of soil water storage in Ili River Valley were analyzed by the multiple linear regression method. The results showed that in terms of soil types, the water storage in 0-120 cm soil layer was in the order of semi-aqueous soil (323 mm) > semi-eluviated soil (213 mm) > calcareous soil (193 mm) > alpine soil (161 mm) > arid soil (108 mm); in terms of of land use types, the water storage in 0-120 cm soil layer was in the order of cultivated land (266 mm) > forest land (199 mm) > garden land (184 mm) > grassland (153 mm). The average water storage of 0-120 cm soil layer in Ili River Valley was about 201 mm, that was 9.56 × 109 m3. Soil bulk density, rainfall, evapotranspiration, normalized difference vegetation index (NDVI) and elevation all had significant effects on soil water storage. Sand content and dryness had effects on soil water storage in 0-30 cm. The slope and profile curvature significantly affected the soil water storage of 0-120 cm.

Key words: soil water storage, land use type, soil order, multiple linear regression, soil water reservoir, Ili River Valley
