摘要
利用遥感监测手段结合现场抽样实测数据,开展桂北地区漓江上游流域沟-塘系统水环境状况调查。遥感共解译沟塘水体2 721处,其中疑似已污染坑塘720处,潜在污染坑塘1 350处,造成水体污染的潜在污染源1 361个,主要为农村聚居地面源污染、厂矿及城镇居民区三类。根据遥感结果选取典型污染区大河乡沟塘中水质进行现场采样监测,测定结果表明:选取的8个沟塘水质均为劣Ⅴ类,主要污染物为COD、磷及氮,与遥感监测结果一致。
The water quality and pollutant sources of ditch ponds in upstream of Li River basin were investigated and monitored by using the remote sensing combined with field sampling.In the total2721investigated ditch ponds,there existed720polluted ditch ponds and1350potential polluted ones.The main pollutant sources included the country non-point source pollution,factories and mines and residential areas and the total number of the three pollutant sources were1361.According to the analysis results of remote sensing monitoring,8ditch ponds were selected as field sampling.The results showed that,the water qualities of the sampled water were worse than Grade V,the main pollutants were COD,TP and TN,and it was consistent with the result of remote sensing monitoring.
