中文摘要:
      为揭示塔里木河(以下简称塔河) 下游河岸带胡杨林盐渍化土壤水分与盐分的空间分异规 律,选取下游河岸2 km 范围内的8 个断面、24 个土壤剖面,测定不同深度(0~10、10~20、20~40、40~ 60、60~80 cm)土壤含水量及盐分数据,运用地统计学方法,探究其空间异质性。结果表明,塔河下游胡杨林土壤以轻度盐渍化为主,空间相关性弱,受随机因素影响显著,不同断面盐分积聚深度有 差异,库木吐格盐分集聚于0~10 cm 表层土壤,魔鬼坝则在40~60 cm 深处土层积聚,且愈靠近台特玛湖盐分愈低。土壤整体含水量<15%,呈干旱化特征,魔鬼坝为中度干旱,其余区域多为重度干旱,库木吐格深层土壤保水能力较强,魔鬼坝水分渗透能力弱,下游区域干旱化程度最严重。
英文摘要:
      To reveal the spatial heterogeneity of soil moisture and salinity in the salinized soil of the riparian Populus euphratica forest along the lower reaches of the Tarim River, 8 transects and 24 soil profiles within 2 km of the lower riparian zone were selected. Soil moisture content and salinity data at different depths(0- 10, 10-20, 20-40, 40-60, 60-80 cm) were measured, and their spatial heterogeneity was investigated using geostatistical methods. The results indicated that the soil in the Populus euphratica forest of the lower Tarim River was primarily mildly salinized, with weak spatial correlation, significantly influenced by random factors. The depth of salt accumulation varied among different transects: salt accumulated in the 0-10 cm surface soil layer at Kumutage, but accumulated in the 40-60 cm deep soil layer at Mogui Dam. Furthermore, salinity decreased closer to Taitema Lake. The overall soil water content was less than 15%, exhibiting characteristics of aridification. The Mogui Dam area was moderately arid, while other areas were mostly severely arid. The deep soil at Kumutage exhibited relatively strong water retention capacity, whereas the water infiltration capacity at Mogui Dam was weak, and the downstream area experienced the most severe aridification.
