【摘要】 随着人们生活质量以及生活品味的不断上升，为了美化人们的生活环境，城市景观水体也越来越多，随之由景观水体水质变差导致的水环境问题也不断的增多。因此，研究景观水体水质修复技术以及运行模式优化措施就显得尤为重要。本文以西安市曲江池水系为例，结合曲江池水体的水质现状，进行水质水量监测，并对水体进行评价，建立水质预测模型，最后研究了水体运行优化模式的一些措施。本文所做的主要工作以及得到的一些结论如下：（1）对西安市曲江池水系资料进行调查整理，并对水量进行监测，建立水量平衡方程进行水量分析，结果表明：曲江池漏损水量较大，不仅造成经济损失，而且对附近建筑物构成危害，最后对其原因进行分析，提出一些可行的减小湖水渗漏的方法。（2）对曲江池水系定点取样并进行水质监测，监测的项目有：TP、TN、NH3-N、CODMn以及DO等，利用模糊综合评价法对监测结果进行评价并与单因子评价法做出对比，结果表明：模糊综合评价法水质监测结果更可靠，曲江池水系部分水域为Ⅲ类水质，其余水域为Ⅳ类水质，水体总体呈现富营养化状态，且TN对水质的影响程度最大。（3）在对水量水质进行分析评价的基础上，使用较为常用的WASP水质预测模型软件，对曲江池水体进行模拟，模拟结果表明：模拟值与实测值变化趋势吻合度很高，因此，利用水质模拟的结果可以预测水质未来的变化，预测水体的补水量和换水量，但模拟值与实测值也有一定的偏差，后续模拟还需加以改进。（4）结合曲江池水系的现状，分析其水质水量监测结果、在分析其水量平衡、水质评价以及水质模拟结果的基础上，调查曲江池景观水系现有的运行模式，从水量平衡保证、水质修复改善以及管理模式优化等方面对城市景观水体运行模式提出具体的优化措施。为曲江池水系现有的运行模式优化提供了参考依据，也为其他景观水体的运行以及长期规划提供依据。更多还原

【Abstract】 With the development of the social economy, the quality and the style of people’slife are also rising, the urban landscape water is more and more present in ourlives.Water environmental problems caused by poor water quality of the landscape arealso constantly increasing. Therefore, the study of landscape water quality restorationtechniques and optimization measures of run mode is particularly important. In thispaper, the water of Qujiang Lake was used as an example to do the following research:Combing with current water quality of Qujiang Lake, testing water quality, and thenevaluating the water bodies, and establishing the water quality prediction model, andfinally giving a number of measures to optimize water run mode.The main work and conclusions of this article are as follows:(1)Take and sort out the data of Qujiang Lake and monitor the water quantity,Establish water balance equation to analysis water volume.The results show that: Alarge amount of water leakage of Qujiang Lake, not only cause economic losses, butalso pose a hazard to nearby buildings.Then analysis the reason,finally, put forwardsome feasible methods to repair water leakage.(2) Sample from the designated points to monitor water quality of QujiangLake.Monitor project includes TP, TN, NH3-N, CODMnand DO, ect. Use fuzzycomprehensive evaluation method to evaluate the monitoring results and makecomparison with the single factor evaluation method, The results show that: fuzzycomprehensive evaluation of water quality monitoring results is more reliable.Part ofwater quality of QuJiang Lake is Ⅲ class,and others is Ⅳ class. The state of the wholewater body is eutrophication, and TN has the largest impact on water quality. (3)Basing on the analysis and evaluation of water quantity and quantity, we use themore commonly used WASP quality prediction model software to simulate the Qujianglake water. The simulation results show that: the simulated and measured values trendshave a high degree of consistent trends. So, the water quality simulation results can beused to predict future changes in water quality and forecast the filling and changingwater quantity for cityscape water. But the measured and simulated values have acertain deviation, the subsequent simulation work also needs to be improved a lot.(4) According to the actuality of the Qujiang Lake, we analyze the monitoringresults of its water quality and quantity, and also the results of water balance analysis,water quality assessment and water quality modeling. Survey the present operatingmodes of Qujiang Lake, propose specific optimization measures for the urban landscapewater running mode to guarantee water balance, improve water quality restoration,optimize the management mode.All those not only can that provide a reference for thepresent operating modes optimization of Qujiang Lake, but also provide the basis foroperation and long-term planning to run of other landscape water.更多还原
