【摘要】 以一起城市河道断面水质突变原因调查为例,对水网地区水环境污染原因调查技术与手段作探索。提出在水文调查方面,采取环保荧光示踪剂法和GPS浮标定位法查清水文流向;在水质变化调查方面,通过历史数据分析寻找水质突变规律,开展现状水质加密监测查明水质突变原因。更多还原

【Abstract】 In this paper,water pollution investigation techniques and methods were discussed in network of rivers taking the cause of a sudden change in water quality in a urban river cross-section for example. It suggested using fluorescent trace and GPS buoy position methods in hydrologic survey,and carrying out water quality encrypted monitoring for finding out the regularity of the sudden change in water quality by historical data analysis.更多还原
