Xianyang Lake is the abbreviation of Weihe River(Xianyang Urban Area Section) Comprehensive Treatment Project,which is to build a partition wall in the middle of the 500 wide Weihe River Valley,then a 270 m wide water storage channel on the north side and a 230 m wide muddy water floodway channel on the south side will be formed.Two rubber dams are constructed in the water storage channels to form a 'Xianyang Lake' with an area of 1.24×106 m2,meanwhile,along both sides of Weihe River in this section,slope protection and flood prevention as well as a series of greening and cultural landscape projects are to be constructed.This project,with flood prevention as the core,aims to improve the living environment and protect ecological environment,and realize the comprehensive treatment of river way flood-proofing,desilting,sewage purification,greening and beautification.The construction of Xianyang Lake greatly improves the image of Xianyang City and generates considerable economic,social and ecological benefits,however,it also has negative effects,such as insufficient lake water supply,original ecology being intervened by human activities,aggravating local fiscal burden,and potential threats to the flood-proofing in the lower reaches of Weihe River.The author puts forwards that 'creating a lake by damming the river' in the process of urbanization and solving the conflicts between sectional interests and integrated interests should follow natural laws and go along the track of sustainable development,which is also the orientation of future work,and the concrete reform scheme is to be further studied. 展开更多

咸阳湖是渭河咸阳城区段综合治理工程的简称,是在渭河谷地500m宽的范围中部修筑一条中隔墙,形成北侧宽270m的泄洪蓄水渠,南侧宽230m泄洪浑水渠,在中隔墙以北泄洪蓄水渠内修建两道橡胶坝拦水,形成水面1.24×106m2的"咸阳湖&quo... 咸阳湖是渭河咸阳城区段综合治理工程的简称,是在渭河谷地500m宽的范围中部修筑一条中隔墙,形成北侧宽270m的泄洪蓄水渠,南侧宽230m泄洪浑水渠,在中隔墙以北泄洪蓄水渠内修建两道橡胶坝拦水,形成水面1.24×106m2的"咸阳湖",同时在本段渭河的两岸建设护坡防洪工程和一系列绿化、人文景观工程。其治水的思路是以防洪安全为核心,以改善人居环境和保护生态环境为主,实施河道防冲、排沙减淤、污水净化和绿化美化的综合治理。它的修建极大地改变了咸阳城市面貌,产生了巨大的生态、经济、社会效益,但同时也产生了湖水补给不足、人类干预原生态的负面影响、地方财政负担加重、对下游防洪形成潜在威胁等问题。笔者认为如何解决城市发展进程中出现的"围水造湖"问题;如何解决局部利益与全局利益的矛盾;如何能够顺应自然走可持续发展之路,是今后的工作方向,具体的改造方案值得进一步研究。 展开更多
