An imbedded integrating ecological entity (IIEE) was designed to combine landscaping, replenishing-water purifying and ecosystem maintaining simultaneously. With this IIEE, within 15 d experiment, simulated replenish water (SRW) with high (SRW-I) or low (SRW-II) nutrients concentration was well purified. Relative removal rates of CODCr, TP, TN, Chl-a and turbidity reached 84.87%, 84.05%, 94.76%, 188.17%, 110.93% when dealing SRW-I, and 52.62%, 90.05%, 82.44%, 166.15%, 202.99%, respectively, when dealing SRW-II. The well grew flora and fauna of IIEE benefit eco-maintaining and landscaping. Separately, the maximal root and stem length-increments ofCyperus altifolius Linn. were 26.1 mm and 28.4 mm, while forPotamogeton crispus Linn. 18.3 mm and 25.7 mm. Mortality for bothBellamya aeruginosa andMisgus anguillicaudatus was both under 2.96%. The analysis of variance (ANOVA) indicated that most experimental indexes in each group performed more significantly better than those in their control. All results indicated that the IIEE is a promising technology for future urban waterscapes construction.
