| 中文摘要:榆神府矿区煤炭资源的大规模开发利用给区域内农业用水带来极大的安全隐患。利用2011-2014年矿区内农业用水的水质监测数据对农业用水安全进行研究。首先依据地表水功能划分的要求分析水质状况，其次评估水质是否满足绿色食品生产环境的要求。结果表明：榆神府矿区用于农业灌溉的地表水综合污染指数为0.292～0.478，部分符合Ⅲ类水质标准，窟野河上游多个断面水质较差，2013-2014年化学需氧量超标率达100%，为Ⅳ类水；矿区内大部分断面水质都符合绿色食品生产环境的要求，但是2014年部分断面的pH有少量超标。为防止农业用水污染，必须加强入境水质监测，增加水污染检测项目，并加强农业用水监测和相关研究。 |

| Abstract:The large-scale development of coal resources in Yulin-Shenmu-Fugu mining area brings a great safety threat to agricultural water there.Using the water quality monitoring data released in 2011-2014, this paper, firstly, analyzed the status quo of water quality based on surface water function area division and then made an estimation on green food production.The results showed that the comprehensive pollution index of surface water is between 0.292 to 0.478, some agricultural water of Yulin-Shenmu-Fugu mining area complies with the water quality standard Ⅲ.However, many water faults of the upstream of Kuye River are in poor conditions the COD exceeding rate is up to 100% in 2013-2014 and some indexes are classified as standard Ⅳ.Most water faults satisfy the green food production environment requirement with a tiny pH value over-standard of some water faults.To prevent pollution in agricultural water, water quality monitor should be strengthened and intensified and more research on agricultural water monitoring should be carried out. |
