乌鲁木齐河流域土壤有机碳与碳酸钙数值分布分析

Analysis on Numerical Distribution of Soil Organic Carbon And Calcium Carbonate Content in Urumqi River Basin

【目的】明确乌鲁木齐河流域土壤有机碳与硫酸钙数值分布,为土地利用和生态保护提供基础数据。【方法】对乌鲁木齐河流域上游大西沟、下游东道海子土壤进行采样和实验室分析,应用SAS-Win对数据进行分析。【结果】了解到采样区域内的土壤,除个别样点外,其有机碳和碳酸钙含量总体来说都比较低,这两项变量的取值都分别在各自的低值区域呈现集中趋势,在整个数值分布区间则分散。【结论】乌鲁木齐河上游土壤中有机碳的含量都处在相对较低的水平,应注意保护植被,在耕作过程中重视土壤盐分的加重情况。

[Objective]The present research investigated the numerical distribution of soil organic carbon and calcium carbonate content in Urumq River Basin to provide the materials for the experiment. [ Method ] The soil samples selected from the lower reaches of Urumqi River Basin were analyzed by SAS - Win in the experiment. [Result and Conclusion] Except some individual sample, in the general, both SOC and CaCO3 contents are reletively low in sampling region. Those two variables values respectively present central tendency in relatively low- value area , and present discrete tendenc in the whole distribution interval.
