On The Spatial Distribution Of Park Greenland In Zhengzhou City

As the lung of a city, the urban green space plays an important role in enhancing the sustainable development and secure citizens'physical and mental health. As the main type of the urban green space, Park greenland reflect the city's environment and image, and offer a place to citizens for excercising, resting and entertaining. With the increasingly urbanizing, planning and constructing of cities are also keeping updating and developing. As an important indicator to evaluate the city's life quality, the park greenery has much to do with the city's distribution and development. What really exists inmany cities is that although the number and area of Park greenland is increasing, it cannot achieve the expected benefits. The main reason is that the relation between the layout of park greenery and city isn't properly handled,which decreases its serving ability. So, it's important to reserch the Spatial Distribution of Park greenland.First,we have been studied the development about city and Park greenland of the city of zhengzhou, summarized the evolution about size,stucture and morphology of city since the first urban planning of Zhengzhou city, analyzed the course of development and distribution of Park greenland of Zhengzhou city,and pointed the influence on the structure of city: Improve the ecology of urban space; Control the expansion of urban structure; Protect and reflect the urban scene;Constructing urban green space system; Improve the city's disaster prevention and mitigation system. Second,we have been analyzed the factors that include government, economy,population, lot level, urbanization and so on ,which inflence on the spatial distribution of Park greenland, and pointed the reasons that cause the differences about Park greenland between different administrative regions or lots. Third, we have been analyzed the spatial distribution of Park greenland as the patchs by the principle use of landscape ecology, and tested the quantified conclusion by the investigation about Park greenland . Last,we have been summerized the shortages about the spatial distribution of Park greenland in Zhengzhou city, and proposed some perfect measures that provide a reference for the current adjustments and future plans about Park greenland of Zhengzhou city.There are still questions that exist in the spatial distribution of Park greenland in Zhengzhou city, especially lack of relational datas and scientific evaluation system, and the shortages which exist in interior of Park greenland.Besides, transformations of the forms in Park greenland and Commonweal in Attached green are all the contents could be explored about improving the spatial distribution of Park greenland, that in order to enlarge the size of Park greenland, strengthen the fusion with city structure, expand the functional attributes of Park greenland.
