| 摘 要： | 以丹江口水库临近三个省份的5个市的调查数据为依据,建立相关的污染物排放估算模型,采用参数计算、对比分析的研究方法,对污染物中所含化学物质(如氨、氮、COD)及其入河量进行估算.结果发现:入库污染总量中,面源污染占绝对优势;在空间分布上,以南阳盆地和十堰地区贡献占绝对优势,库区区间贡献率较小;在化学元素的形态特征上,对水体的影响主要是以溶解态为主的氮和以颗粒状为主的磷.从面源污染的源头来看,不合理的土地利用造成的土壤侵蚀,薄弱的生态环境所造成的污染物转移,都是造成面源污染步步加深的原因.针对以上对汉中、南阳等5个市之间面源污染总量差异的分析,因地制宜地提出未来丹江口水库农业面源污染治理的科学对策,为丹江口库区的环境保护提供科学依据和借鉴.

| Abstract: | On the basis of survey data from five towns near the Danjiangkou Reservoir in three provinces, a relevant pollutant emissions estimation model is established to estimate the levels of chemical substances （such as ammonia, nitrogen, COD） in pollutant and pollutant quantity inlets into river water. The results show that nonpoint source pollution is the domination in total pollution while Nanyang basin and Shiyan area dominate the pollution according to spatial distribution. The non-point source pollution indicates that land-erosion and pollutant transfer are the chief culprit. Based on the analysis of non-point source pollution from the five cities Hanzhong , Ankang , Shangluo, Shiyan and Nanyang, countermeasures for non-point source pollution from agriculture is proposed to reduce environmental pollution and provide scientific reference. |
