利用公众调查取得的信息,分析了圭塘河目前水污染状况及主要的污染原因。大部分受访居民认为圭塘河水质污染严重,水质污染从20世纪90年代开始恶化,并且入水量较以前减少。从水污染原因来看,多数居民认为是生活污水排放所致,也有部分居民认为是城镇化导致的地表改变所致。从环境保护措施上来看,目前政府应加大保护力度,除了加强垃圾、污水处理厂处理能力外,还需要从湘江或圭塘河引入清洁水,加大水量,以减少河水污染。

By using the information from public investigation, the current situations and the main causes on water pollution of Guitang River were analyzed. Most of the respondents think that water pollution of Guitang River became serious since the 1990s, and inflow water reduced than before. From the point of view of water pollution causes, the majority of rEsidents recognized that domestic sewage discharge is the main reason, while some residents believe that the reason should be the change of the surface caused by urbanization. From the point of view of environmental protection measures, the government should increase the protection efforts.
