新建园区水生态自净化生物修复技术研究——以熊猫基地扩建工程为例

由于新建城市生态园区内人工湖泊等水源水质达不到标准，需在建设过程中构建园区水生态自净化系统，为此，以成都熊猫基地扩建工程为例，通过分析熊猫生存场域环境内的地形数据，构建湖区水环境屏障系统。通过场域内地形汇水分析与汇水点模拟，分析湖体污染负荷，模拟野生大熊猫的水生态环境，构建自净化立体水生态体系。结果表明，自净化立体水生态系统构建后，TSS(总悬浮固体)、TN(总硝酸盐)、TP(总磷)大幅消减，生态园区内逐步实现了从地表Ⅲ类水体到Ⅱ类水体净化提升。

Research on Self-purification Bioremediation Technology of Water Ecology in Newly Built Park:Take the expansion project of Panda Base as an example

As the water quality of artificial lakes and other water sources in the newly built urban ecological park cannot meet the standards, it is necessary to build a water ecological self purification system in the park during the construction process. Therefore, taking the expansion project of Chengdu Panda Base as an example, the water environment barrier system in the lake area was built by analyzing the terrain data in the environment of the panda habitat. Through the terrain catchment analysis and catchment point simulation within the site, the pollution load of the lake was analyzed,the aquatic ecological environment of wild giant pandas was simulated, and a self- purification three-dimensional water ecosystem was built. The results show that TSS (total suspended solids), TN (total nitrate) and TP (total phosphorus) have been significantly reduced after the construction of the self purification three-dimensional water ecosystem, and the purification of the ecological park has gradually improved from surface Class III water body to Class I water body.
