| 摘 要： | 对塔里木河上游地区的植被进行调查,确定了该区域有7个植被群落。利用数理统计方法分析不同植被群落覆盖和同一植被群落盖度对不同深度(0~5 cm,5~10 cm,10~20 cm,20~40 cm,40~60 cm,60~80 cm,80~100 cm,100~150 cm)土壤有机质的影响,结果表明:胡杨-铃铛刺群丛覆盖下,0~60 cm土壤有机质随盖度的增加而增加,胡杨-多枝柽柳群丛和多枝柽柳群丛覆盖下,0~150 cm土壤有机质随着盖度的增加而增加。在这7个植被群落中,以胡杨-芦苇群丛覆盖下,0~100 cm土壤有机质含量较高,而胡杨群丛和多枝柽柳群丛覆盖下,0~100 cm土壤有机质含量较低。

| Abstract: | Based on the data of investigation,7 communities were confirmed in the uptream region of Tarim River.The method of mathematical statistics was used to analyze the effects of different vegetation on the organic matter in different depths of soil(0-5cm,5-10cm,10-20cm,20-40cm,40-60cm,60-80cm,80-100cm and 100-150cm).The results showed that the organic matter in 0-60cm soil increased with the increase of vegetation covering rate in Ass.Populus euphratica Oliv-Halimodendrum lolideneon,and the organic mater in 0-150cm soil increased with the increase of vegetation covering rate in Ass.Populus euphratica OlivTamaricaceae ramosossoma Ledeb and Ass.Tamaricaceae ramosossoma Ledeb.In the 7 vegetation comunities,the soil organic matter in depth of 0-100cm was the highest in Ass.Populus euphratica Oliv-Phragmites australis(Cav.)Trrin.ex Steud,and the lowest in Ass.Populus euphratica Oliv and Ass.Tamaricaceae ramosossoma Ledeb. |
