- 摘要:
- 对采自天山北坡东段（巴里坤—伊吾区段）和西段（昭苏—特克斯和新源—巴音布鲁克区段）下林沿土壤剖面（0—5，5—20，20—40 cm）共计133个土壤样品的有机质含量进行了测定，比较分析了不同区段林沿土壤有机质含量的空间差异。结果表明：天山北坡西段林沿土壤剖面层的有机质含量明显高于天山北坡东段。0—5，5—20，20—40 cm土层内土壤的有机质含量均表现为东段低于两段；0—5 cm土壤剖面层内昭苏—特克斯区段的土壤有机质含量高于北坡其他区段。5—20，20—40 cm剖面层内土壤北坡新源—巴音布鲁克区段的土壤有机质含量高于北坡其他区段。天山北坡0—5 cm剖面层内土壤有机质含量的最大值出现在昭苏—特克斯区段，5—20，20—40 cm土层土壤剖面层内有机质含量的最大值出现在新源—巴音布鲁克区段。0—5，5—20，20—40 cm土壤剖面层内土壤有机质含量的最小值出现在巴里坤—伊吾区段。0—5，5—20，20—40 cm土壤剖面层内巴里坤—伊吾区段的变异系数最大。0—5 cm土壤剖面层内巴里坤—伊吾区段的土壤有机质含量的变异系数属于强变异，其他两个区段土壤有机质含量的变异系数属于中等变异。5—20，20—40 cm土壤剖面层内研究区域的有机质含量的变异系数属于中等变异型。
- Abstract:
- 133 soil samples collected from three sections of the northern slope of the Tianshan Mountains were used to measure the organic matter contents in order to acquire the spatial pattern of soil properties affected by different climate conditions and human activities. The results showed that organic matter contents of soil samples collected from the western section were much higher than those gotten from the eastern section of the northern slope of the Tianshan Mountains. In view of the 0—5, 5—20, 20—40 cm soil layers, soil organic matter in the eastern section of the northern slope of Tianshan Mountains (Balikun—Yiwu Section) was lower than that in the western section. Soil organic matter content in 0—5 cm soil layer in the Zhaosu—Tekesi section was more than that in other sections. Soil organic matter contents in 5—20 cm, and 20—40 cm soil layers in the Xinyuan—Bayinbuluke section were more than those in other sections. The maximal soil organic matter content in the 0—5 cm soil layer appeared in the Zhaosu—Tekesi section, while those for the 5—20 cm and 20—40 cm soil layers appeared in the Xinyuan—Bayinbuluke Section. The minimal soil organic matter contents in the 0—5, 5—20 cm and 20—40 cm soil layers appeared in the Balikun—Yiwu Section. In view of the 0—5, 5—20 cm and 20—40 cm soil layers, the Balikun—Yiwu section had the largest coefficient of variation (CV). The CV of 0—5 cm soil layer in the Balikun—Yiwu section was the largest, while those in other two sections were medium. The CV of soil organic matter content of the 5—20 cm and 20—40 cm layers were medium. The maximal soil organic matter content appeared in the 0—5 cm soil layer of the northern slope of Tianshan Mountains (Zhaosu—Tekesi, Xinyuan—Bayinbukuke, Balikun—Yiwu). The minimal soil organic matter content in the Zhaosu—Tekesi section and Xinyuan—Bayinbuluke section appears in the 20—40 cm soil layer, while that in the Balikun—Yiwu section appeared in the 0—5 cm soil layer. Soil organic matter content in the 0—5 cm soil layer in the northern slope of Tianshan Mountains (Zhaosu—Tekesi, Xinyuan—Bayinbuluke, Balikun—Yiwu) was more than those in the 5—20 cm and 20—40 cm soil layers.
