Tianjin Binhai New Area Of ​​functional Plant Ecology Application And Its Principal Components Analysis And Evaluation

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.
