By monitoring the water quality (Dec., 2009-2011) of the three sections of the moat in Xuchang, the data show that three-year average turbidity of the water at North, East, South sections is 18.6,16.7 and 12.4 respectively, and with average COD at 43 mg / L, 37.5 mg / L and 29.5 mg / L in accordance, as well as with BOD5 content at 16.1mg / L, 15.0mg / L and 8.7 mg / L. The integrated pollution index of the three mentioned sections was 2.54,1.94 and 1.06 in December 2011, increasing by 29.6%, 22% and 34.2% in comparison with the same period in 2009. The fluorescence spectrometer tests display that the main components of organic pollutants at the northern and eastern sections are organic detergent, cooking oil and a variety of plant and animal protein in complex traits.

In this study, three species of water ornamental plants, Lythrum salicaria, Typha angustifolia and Iris wilsonii, were introduced to removing nitrogen and phosphorus in lightly polluted urban landscape water. The results showed the experimental plants were all growing well in lightly polluted water and the growth rates were: Lythrum salicaria 33%, Iris wilsonii 19% and Typha angustifolia16%, respectively. The removal efficiency of TN of Lythrum licaria, Typha angustifolia and Iris wilsoni were 55.42%, 62.65% and 57.59%, respectively. The removal rates of TP of three species of hydrophytes were Lythrum licaria 63.9%, Typha angustifolia 51.7% and Iris wilsoni 38.9%, respectively. Based on the removal efficiencies on nitrogen and phosphorus and landscape efficiency, the three species of water ornamental plants were recommended as pioneer in aquatic vegetation restoration in urban lightly polluted landscape river.

As an important part of urban water system, urban landscape water plays a significant role in the improvement of urban ecological effect, such as adjusting regional climate, increasing water vapor content and reducing urban heat land effect. At present, the pattern of landscape water has a lot of research findings, but quantitative analysis of the impact on ecological function of urban landscape water is too little. This paper took hydrologic station upstream in Huangtaiqiao in Jinan city as study area and respectively compared ecological effect of landscape water with land surface on adjusting regional temperature from two periods of annual and summer evaporation. The result shows that landscape water does better in this aspect. So it is essential to pay extraordinary attention to reasonably planning landscape water of land use in the future in order to give full play to its ecological effect.

The bioremediation technology for urban landscape waters are illustrated in this paper. The characteristics and purification performance of urban landscape waters were introduced. Based on their good effects on nitrogen and phosphorus removal, the landscape plants are recommended as species of aquatic vegetation in phytoremediation of wastewater of urban river.
