摘要 The root causes of urban landscape water pollution were analyzed in this study, the bio-ecological restoration technologies combing both exogenous and endogenous pollution control were put forward. 1景观水体污染原因分析按生态学观点分析,景观水体污染的原因实为生态失衡。总结来看主要有以下几方面原因:①补给水问题。一是补给水水质尚未得到控制,源头水中氮、磷等营养元素较高;二是补给水水量不足,造成水体自净能力下降。②水体流动性差。③大气沉降污染。包括颗粒态和溶解态污染物质,如尘土、氮磷、硫化物等。
