盘活现有设施，避免赛后闲置；用好科技手段，协同参与减碳；完善配套服务，落实环保政策……第十 五届全国运动会（以下简称"十五运会"）日前在粤港澳大湾区落下帷幕。秉持"绿色、共享、开放、廉 洁"的办赛理念，十五运会通过系统性创新实践，致力打造一届"碳中和"赛事。 场馆建设是赛事减碳的关键环节。本届全运会中，粤港澳三地充分利用现有场馆资源，避免新建工程产 生的碳排放，对现有场馆进行绿色升级改造。 广东赛区90%以上的场馆都是利用现有场馆进行维修改造提升，同时不新建运动员村；香港赛区秉 持"利用现有场馆、市场化运作、不扰民"原则，利用启德体育园、香港单车馆、粉岭高尔夫球场等既有 场地举办8个竞赛项目和1个群众项目；澳门赛区的赛事除了使用特区政府体育局的场地外，还会利用当 地大专院校、综合度假休闲企业的场馆及设施举办比赛。 值得一提的是，十五运会的低碳实践未止步于"赛事期间"，也同样关注"赛后使用"，即确保场馆能够持 续服务城市发展与全民健身事业，避免"赛事一结束、场馆就闲置"的资源浪费困境。例如深圳龙华文体 中心赛后将面向市民开放，成为文体活动的综合空间。广州大学城体育中心攀岩场馆则将转型为青少年 攀岩基地，真正实现 ...

Core Viewpoint - The construction of the South Ahmad City infrastructure project in Kuwait focuses on water management, addressing challenges related to groundwater, rainwater, and wastewater treatment [1][2][3]. Group 1: Groundwater Management - The project site has an average of 1-2 meters of groundwater, with seawater intrusion causing significant challenges during construction, including water levels reaching up to 2.5 meters [2]. - Six dewatering solutions were developed to manage groundwater levels, including surface recharge measures to maintain ecological balance and utilize excess water for construction needs [2][3]. Group 2: Rainwater Management - The project incorporates sponge city technology to collect and recycle rainwater, with plans to install approximately 76,009 rainwater collection units and over 264 kilometers of rainwater pipelines [3]. - The rainwater collection system is designed to support irrigation for green spaces, with a capacity to provide enough water for 50 acres of vegetation for a year after a single collection [3]. Group 3: Wastewater Management - The project will provide modern living conditions for at least 100,000 residents, integrating wastewater treatment and reuse into its design [3][4]. - Over 260 kilometers of wastewater pipelines will be installed, with a treatment capacity exceeding 50,000 cubic meters, allowing treated wastewater to be used for irrigation [3][4]. Group 4: Project Scale and Impact - The South Ahmad City infrastructure project covers an area of approximately 52.79 square kilometers and employs over 1,400 workers [4]. - The timely completion of the project is expected to alleviate housing pressure in the old Ahmad area, enhancing the living environment for local residents [4].
