摘要/Abstract

摘要： 近年来,地下水超采和不合理的灌溉方式导致民勤绿洲北部地区严重盐渍化.盐爪爪(Kalidium foliatum)群落是高度盐渍化地区主要的盐生、旱生群落.采集盐爪爪群落下部以及群落间空地的土壤样品和盐爪爪植物样品,分析了盐爪爪群落对土壤盐分的影响.结果表明,随着与盐爪爪群落距离的增加,土壤盐分增加;这种空间变化主要发生在土壤表层(0～5 cm);盐爪爪茎的盐分含量显著高于根和叶,与冠层下0～5 cm土壤盐分接近、高于5～10 cm土壤盐分;盐爪爪从土壤吸收的Na⁺、Cl^-、和SO₄^2-主要存储于茎部,而Mg²⁺存储于叶部.

Abstract: Over-exploration of underground water and unreasonable irrigation patterns lead to severe soil salinization in the Minqin Oasis at the downstream of the Shiyang River of China. Kalidium foliatum is the major halophytes and xeric community surviving in the area. We investigated the electricity conductivity (Ec) of soil and Kalidium foliatum samples to detect how the Kalidium foliatum affect soil salinity. Results showed that soil Ec increased with the distance from the Kalidium foliatum canopy, and the spatial difference mainly occurred in the surface soil layer (0-5 cm). Ec in the stem of Kalidium foliatum was higher than in root and leaves, which was similar to the Ec in 0-5 cm soil under canopy. Irons like Na⁺, Cl^- and SO₄^2- absorbed from the soil was mainly stored in the stem, whereas Mg²⁺ in leaves.
