China has wide distribution of salin e soil, landscape water which use saline soil as matrix will be salt accumulation in the long-term effect of high salinity. In many arid regions, water evaporation, precipitation can replenish evaporation causes water salinity rising. Landscape water quality of the output will be more obvious impact. Aquarium simulation test using devices to reclaimed water as test water, water with added NaCl salinity were 0,3,6,9 and 12 g/L, the effects of different salinity of reclaimed water for the landscape water quality changes of water. The results showed that the water quality changes in the landscape of reclaimed water with different salinity differences in the conditions for the water significantly. Low salinity water quality to deteriorate significantly, high salinity water exhibited inhibition of the growth of algae, salinity can cause significant changes in the population of algae advantage.%我国盐渍土分布十分广泛,盐渍土为基质的景观水体在长期的积盐作用下盐度较高.且在很多干旱地区,水体蒸发量大,降水不能补充蒸发量导致水体盐度不断升高.对景观水体水质会产出比较明显的影响.试验采用水族箱模拟装置,以再生水为试验水体,添加NaCl配备水体盐度分别为0,3,6,9,12 g/L,考察不同盐度条件再生水为水源的水体水质变化规律.试验结果表明不同盐度条件下再生水为水源的水体水质变化差异明显.低盐度水体水质恶化明显,高盐度水体表现出对藻类生长的抑制,盐度升高能够引起水体中藻类优势种群的明显变化.
