【摘要】 天津滨海新区是拉动天津市及环渤海地区经济的主战场,也是面向全国与世界展示天津风采的窗口。在资源消耗、废弃物排放及城市绿化体系建设中,依据生态建设理论,做好生态背景调查工作,充分发挥功能植物以及生态资源优势,才能实现天津滨海新区高效的生态转化功能,创建滨海新区社会经济与生态环境建设协调可持续发展要求。本文根据天津滨海新区的自身优势,以及滨海新区生态环境与资源配置状况,实现对滨海新区资源节约与生态发展模式的定量分析,提出适合新区资源节约及生态发展模式与其对策。本文的主要内容概括如下：(1)概述了生态城市的内涵与发展,在此理论基础上阐述了滨海新区的自身状况以及各种功能植物的主要应用现状。(2)运用主成分分析法,建立绿化树种评价模型。对天津滨海新区常见42种绿化树种进行综合评价分析及排序,选出了适合天津滨海新区绿化的树种如：柽柳(Tamarix chinensis Lour)、绒毛白蜡(Fraxinus velutina)、泡桐(Paulownia)等,为滨海新区的绿化树种的选择提供一定的依据。(3)天津滨海新区水资源短缺,文章全面分析了滨海新区的污水排放现状、城市再生水的利用情况以及传统污水厂存在的问题,依据滨海新区有利的地理气候环境,提出了符合生态型滨海新区的污水处理技术,即“生态塘组合工艺处理技术”。(4)运用主成分分析法,分别对滨海新区农作物种植面积、农作物总产量和农作物单位产量的6个因子进行分析,在此基础上分析了天津滨海新区发展生态农业的优势条件和限制因素,最后得出,调整滨海新区的农业结构是提高农民收入的途径之一,同时根据滨海新区的生态环境和发展布局,提出适合滨海新区生态农业发展的新模式。更多还原

【Abstract】 The new developed area of Binhai in Tianjin is the window showing off Tianjin city figure well around the country and the world, also turns into the main battlefield to promote the regional economic development on Tianjin city and economic developing Circum-Bohai-Sea Region. Based on ecological environment construction theory, ecological background investigate effects were implemented during ecological system construction concerned with resource depletion management, waste release control and city greening engineering. Through fully revealing greening action of functional plants and advantages of other ecological resource, efficient regional ecological transformation function can be finished. In this paper,combined with its own dominant characteristics, ecological environment characteristic and resource configuration status in the new developed area of Binhai in Tianjin was mainly studied by quantitative pattern analysis approach about its resource economizing and ecological development mode.An ecological development mode and its corresponding measure was introduced. Research result can be seen in the following:(1) General description on the meaning and developing conlcept of the ecologicalcity is introduced,and based on this points its own status and use condition on all kinds of functional plants is presented.(2) Mathematical evaluation model for street greening tree was set up by using of PCA (Principal component analysis).The street trees such as Tamarix chinensis Lour Fraxinus velutina Paulownia and so on,are selected as competent greening trees in this new developed area by comprehensive analysis and evaluation prior to precedence order to 42 kinds of common greening trees in Binhai New Area of Tianjin.(3) Aiming at the situation of its water shortage, actual situation of wastewater release and reused and the traditional sewage treatment plants in Tianjin Binhai New Area was analyzed, and by comprehensive consideration to favorable environment of geography and climate in Binhai New Area, "ecological pond combination technology" is proposed.(4) Six contributing factors including in crop acreage, gross crop output, unit crop output and so on, were separately analyzed by APH. Research result showed that and further analysis to advantages condition and limiting factors were done.The last result showed that one of efficient paths increasing farmer incomes is to adjust agricultural structure of production in Binhai New Area. Moreover, in the paper, a new agricultural development mode suitable to Tianjin Binhai New Area was introduced according to its ecological environment condition and development layout requirement.更多还原
