摘　　要：为了优化城市生态水库设计,采用GIS技术和改进聚类算法对张掖市二坝水库进行设计。通过收集水文、地形和土地利用数据,利用GIS进行空间分析和建模,提高蓄水容量和防洪效率等。结果显示,设计后水库的蓄水容量从125 000 m^(3)提升至185 300 m^(3),防洪效率提高至88.2%,水质净化指数降至4.9mg/L,生物多样性指数增至0.85物种/m^(2),植被覆盖率增至72.6%。GIS技术在提升城市生态水库的生态功能和城市景观价值方面具有显著效果。In order to optimize the design of urban ecological reservoir,the second dam reservoir in Zhangye city was designed by using GIS technology and improved clustering algorithm.By collecting hydrological,topographic and land use data,GIS is used for spatial analysis and modeling to improve water storage capacity and flood control efficiency.The results show that after the design,the storage capacity of the reservoir is increased from 125000 m^(3) to 185300 m^(3),the flood control efficiency is increased to 88.2%,the water purification index is reduced to 4.9 mg/L,the biodiversity index is increased to 0.85 species/m^(2),and the vegetation coverage rate is increased to 72.6%.GIS technology has a remarkable effect in improving the ecological function and urban landscape value of urban ecological reservoirs.
