中文摘要	干旱流域水质恶化已成为不可忽视水环境问题,其显著特点为水量较小,污染严重,改善任务十分艰巨。本文以张家口市境内永定河上游为例,根据水体污染现状,选取化学需氧量、氨氮和总磷作为容量核算因子,应用适用于干旱区的改进系数公式法,研究张家口市永定河上游流域的水环境容量及其合理分配问题。结果表明:张家口市永定河上游流域化学需氧量、氨氮和总磷的水环境容量分别为16 264.4、789.15、183.64 t·a~(-1);工业、城镇生活、农村生活、农业面源、畜禽养殖和旅游业的化学需氧量削减量分别为317.05、3 108.66、318.10、67.14、130.19、 207.57 t·a~(-1);氨氮削减量分别为72.83、1 212.64、238.95、45.48、237.37、97.89 t·a~(-1);总磷削减量分别为2.23、61.48、 12.35、4.49、10.87、3.39 t·a~(-1)。研究所得永定河上游张家口区域内水环境容量科学合理,为张家口市相关部门开展水环境治理、制定重点企业排放限值提供了科学依据,具有切实可行的实际意义。
英文摘要	The deterioration of water quality in the watersheds of arid regions has become an issue that cannot be ignored.The salient features of such deterioration are small water volume and high levels of pollution, and the task of improvement is very difficult.This report focusses on the upper reaches of Yongding River in Zhangjiakou City.According to the current water pollution status, the chemical oxygen demand(COD), ammonia nitrogen and total phosphorus are factors that affect capacity, and the improved coefficient formula method suitable for arid areas was applied to study the water environmental capacity and rational allocation of the upper reaches of the Yongding River in Zhangjiakou City.The results showed that the water environmental capacity of COD, ammonia nitrogen, and total phosphorus were 16 264.44, 789.15 and 183.64 t·a~(-1),respectively.The COD reductions for the industry, urban life, rural life, agricultural sources, livestock and poultry farming and tourism sectors were 317.05, 3 108.66, 318.10, 67.14, 130.19, and 207.57 t·a~(-1), respectively;the ammonia nitrogen reductions were 72.83, 1 212.64, 238.95, 45.48, 237.37, and 97.89 t·a~(-1);and the total phosphorus reductions were 2.23,61.48, 12.35, 4.49, 10.87, and 3.39 t·a~(-1), respectively.The water environmental capacities measured in Zhangjiakou area on the upper reaches of Yongding River are scientifically sound and within reasonable expectations, and provide a scientific basis for the relevant administrative departments of the city to carry out water environment management and to formulate discharge limits for key enterprises, which has a practical significance.
