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。

On the basis of survey data from five towns near the Danjiangkou Reservoir in three provinces , a rele-vant 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 non-point source pollution is the domination in total pollution while Nanyang basin and Shiyan area dominate the pol -lution 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 pro-posed to reduce environmental pollution and provide scientific reference .
