Environmental Challenges
环境条件挑战
气候干燥,蒸发量约为降雨量的三倍,水资源短缺
现有水体污染严重,需较大成本的水质处理投入
土壤盐碱化严重,植物生长受到限制,植载成本高
生态特征单一且脆弱,生物多样性低
流域末端,积聚上游大量污染,难以调控
临近渤海,易受水涝灾害和风暴潮的影响
快速土地开发模式对生态环境的压力
Environmental Constraints
Dry climate, evaporation is about 3 times of rainfall, leading to water resources shortage
Entire water environment is poor: Poor circulation, polluted water, notably 2 sewage rivers in the north and south boundaries
Existing plant condition is degraded, leading to low biodiversity
Soil salinization creates few adaptive species and high cost of planting

Environmental Opportunities
环境条件机遇
临近区域大型湿地等生态良好区,位于主要的候鸟迁徙廊道
水面面积大,具有形成良好内循环的基质,并可通过底泥清理和水质生态控制,带来整体水环境的改善
导入土壤改良策略,通过植栽配置应对盐碱化问题,塑造多样化景观效果
存在新能源和新技术的开发和应用机遇
具有自然本底向开发建设区“渗透”与“反渗透”的功能,成为天津生态城的重要生态保障区和滨水景观区
将成为可持续发展的典范,为平衡城市开发与生态修复提供典型案例
环境修复为旅游开发和环境教育带来机遇
Environmental Opportunities
Abundant water systems with many channels form a good base for plete water cycle
Create protected wetlands or wetland parks to improve existing habitats
Water quality improvement through filtration and bio-treatment to improve habitat potential, and create efficient water circulation to improve water cleansing processes
Provide environmental and nature education to encourage interest in wildlife to increase recreational value of the area
8
景观机遇
建立长期生态可持续性景观策略的机会
提供一个全面的景观规划方法,以综合考虑水资源管理、防洪、可持续发展和生态等方面
提供一个协同的方法,使区域性策略得以实施,不同项目间得以协调(能更有效地利用财务资源)
新建美观且功能明确的多功能开放空间系统
Landscape Opportunities
Possibility of creating long term sustainable Landscape polices
Creating a sound landscape planning approach that would integrate water management, flood control, sustainable and ecological approach
Creating a coordinated approach allowing for implementation of a district wide strategy and harmonization of projects (more efficient use of financial recourses)
Creation of multifunctional open work with clear defined funct
