摘要:
通过对绿洲内部不同环境介质定点采样和室内分析，研究了绿洲主要非点源污染物氮素和磷素在绿洲内部不同环境介质中的分布和相互迁移规律。研究发现绿洲河流中的氮和磷的含量呈现出沿河流流向上升趋势，河水中氮素含量最低值（0.399mg/L）出现在河流出山口，最高值（1.707mg/L）出现在人类活动密集区的绿洲核心地区，该值比源头的第一个最低值增加了3倍，相当于每1 km约增加了9.6μg/L；河水中的磷素含量最低值同样是出现在了河流出山口，含量为3.13mg/L，最高值出现在绿洲末端，为26.46mg/L。农田土壤中的氮和磷的含量普遍高于农田边缘地区的非耕作土壤，不同农作物土壤中的氮和磷的含量也有所不同，稻田土壤中氮含量相对于别的农田较高为0.338g/kg，果园土壤中的磷含量较高为0.367g/kg。采集的农田排水中氮和磷的含量普遍比河水中的含量高，最高已高出3倍以上。不同环境介质中氮素和磷素含量相关性而言农田排水和河水氮素含量，农田土壤和河水中的磷素之间的相关性较高说明它们之间氮素和磷素的相互转移比较明显。
Abstract:
In this article we sampled soil,river water and seepage and total phosphorus,total nitrogen in these samples are analyzed.According to the obtained data,the distribution character of total phosphorus and total nitrogen in each environment and its change character were identified.And we also analyzed the impact between each index.The result showed that:the concentrations of total phosphorus and total nitrogen bring forward the increasing tendency along with the river’s streamline.The lowest nitrogen (0.399mg/L) and the phosphorus (3.13mg/L) appear in the oasis area where is at the end of irrigation land.The highest nitrogen (1.707mg/L) and phosphorus (26.46mg/L) appear in the beginning of the river.Through the comparison between the soil on the field and uncultivated soil,it shows that 66.67%～77.78% of field soil component of total phosphorus,total nitrogen in the whole sampling area is higher than those in uncultivated soil.The correlation analysis brings out that the total phosphorus in soil and river water and total nitrogen in river water and seepage water show correlative.
