摘  要:
综合运用地理信息系统(GIS)、水质预测模型、数据库、空间分析技术,实地采集盘龙江水样数据,以GPS空间位置点数据和QuickBird影像为基础,采用纳氏试剂比色法测定了盘龙江水样氨氮含量。使用样条函数插值的方法,对其现状水质进行了分类。对盘龙江下游河段,综合考虑缓冲区内居民和农田因素,同时简化了完全混合模型,预测了该区域的氨氮含量。

摘  要:
The Nessler's reagent colorimetry method has been taken to determine the content of Ammonia-nitrogen based on the data of water samples,spatial location of GPS points and QuickBird images integrated technology of Geographic Information System,water quality prediction models,databases and spatial analysis.After using the spline interpolation method to classify its water quality status,the paper predicted the content of Ammonia-nitrogen level on the comprehensive consideration of factors such as residents and farmland in the buffer zone,while simplifying the completely mixed model downstream of the river.
