中文摘要:

以德州引黄灌区为例,探讨灌区主要水系部分水化学特征及硝态氮(NO-3-N)与铵态氮(NH+4-N)污染状况。结果表明,pH、电导率(EC)、NO-3-N及NH+4-N含量存在明显的空间差异。NO-3-N受人类活动影响,灌区北部卫运河-漳卫新河以及德惠新河污染严重,呈带状分布;而马颊河及徒骇河受引黄水补给的影响范围较广,污染程度相对较低。NH+4-N污染除卫运河外,主要呈点源分布,各水系均有超标河段,而影响NH+4-N的可能因素更多,有待进一步深入研究。本研究为评价该区引黄灌渠对NO-3-N和NH+4-N的影响提供科学依据。

英文摘要:

This paper investigated water chemical characteristics and the contamination of nitrate nitrogen and ammonium nitrogen in main river reaches of Dezhou irrigation district.The results indicated that pH,electrical conductivity,nitrate nitrogen(NO-3-N) and ammonium nitrogen(NH+ 4-N) varied spatially.Serious contamination by NO-3-N was found in the Weiyun and Zhangweixin Rivers with strip-flume along these rivers.Lower values were measured in the Majia and Tuhai Rivers due to water-transfer from the Yellow Rive...
