摘 要:通过西部原油成品油管道工程土壤环境中对照样点与扰动点的pH值、有机质(TOC)、全氮(TN)、全磷(TP)现场调查和土壤监测,结果表明:对照样点与扰动点表、底层土壤的各项指标均存在显著相关性(N=25,p<0.01);对照样与扰动样表、底层土壤指标的差异性受到管线建设前后干扰,表层土壤:pH值、全氮、全磷都没有显著差异(成对数据t检验,自由度df=24,p>0.01),有机质差异显著.底层土壤:pH值、全磷都没有显著差异(自由度df=24,p>0.01),有机质和全氮差异显著;各样点之间土壤属性的差别很大,但同一个点受干扰前后各土壤属性值差别不大,说明工程建设对土壤的影响在可接受的范围内.Field investigation and soil monitoring were carried out of pH, TOC (total organic carbon), TN (total nitrogen) and TP (total phosphorus) of the environmental soils at the control sampling points and the disturbance points of Petro China Western Crude-Oil and Petroleum Products Pipeline Project. The re- sults showed that the soil indicators studied were significantly associated(N = 25, p〈0. 01) between the top soil layer and the subsoil layer at the control points and the disturbance points. The differences in the soil indicators at the top soil layer and the subsoil layer at the control points and the disturbance points were interfered by the pipeline construction. In the surface soil, pH, TN and TP were not significantly different between the control points and the disturbance points (paired-sample t test, df=24, p〉O. 01), while TOC was significantly different. In the bottom soils, pH and TP were not significantly different (df =24, p〉0.01) but TOC and TN were significantly different between the control points and the disturb- ance points. However, the disturbance caused by the Pipeline Project resulted in no significant differences in the soil properties investigated, suggesting that the impact of the construction on soil remains in an ac- ceptable range.
