材料一：上个世纪末，随着广州城市规模扩大和人口膨胀，河涌成了“排污渠”、“臭水沟”， 不少河涌发黑发臭，一堆堆垃圾漂浮在河面上，水污染比较严重。“母亲”河珠江也逐渐变成了一条日夜在城市中翻滚的“黑龙”，这不但严重影响流经区域居民的生活，更有损广州城市的形象。（注：河涌,是指用于防洪、排涝、排水、航运的天然河道(珠江干流、流溪河除外)、人工水道、人工湖泊。）

材料二：早在1997年，广州市就启动了河涌整治工作，建成污水处理系统4个，污水处理能力达到159万吨/天，但河涌污染仍是一大顽疾。未来18个月内,广州市还要投入458亿元用于污水治理和河涌综合整治,确保每年从北江引水23亿立方米,向河涌补水清洁珠江保卫母亲河；“一湾溪水绿,两岸荔枝红”的岭南水乡风韵亦有望早日重现。
