Spatial Distribution Characteristic

With the requirement of the construction of water eco-civilization, the urban development in Northern China have paid more attention to the construction of landscape water. The spatial pattern of landscape water directly affects urban ecological function, but now, the study of this field is too little. Four typical distribution of landscape water area in Jinan, Weifang, Linyi and Jining of Shandong province, China were selected as study areas, four appropriate spacial indexes, such as suitable ratio of water surface area, shape index, evenness index and dispersity index were adopted and the corresponding standard for each index were determined to compare four cities’ landscape pattern with comprehensive analysis. So it is essential to reasonably plan landscape water area of land use in the future in order to give full play to its ecological effect in cities.

Urban Landscape Water

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.
