The Research Of The Hilly Urban Spatial Layout With Natural Elements

With the accelerated process of urbanization in China，natural environment hadbeen severely damaged，urban space resources become increasingly tense. The urbanconstruction have to consider the use of the hilly plain ar eas under the policy of arableland has been protected strictly. However, the hilly natural ecological elements withrichness, diversity and complexity property, we urgently need to explore a reasonablemeans of planning and design, both to meet the needs of urban expansion andmaintaining the natural ecological environment. Based on the above background, thisthesis from the perspective of urban and rural planning, follow the main line of urbanecology, to explore the interrelationship between the elements of the naturalecological characteristics and layout of urban space in the hilly city, find a suitablespace layout mode joint the physical space construction with the natural ecological,which make great practical significance and application value of current developmentsituation in hilly city.This thesis comprises four components: the research of basic theoretical, theinterrelationship between natural elements and urban spa tial layout, the method ofspatial layout and case studies. First, we summarized the theory of spatial layout andurban ecological, and introduced a new perspective to the city from urban ecology andtake eco-city as a goal of the current urban construction, which forms the basic ideasand theoretical basis for this study. Then, for the hilly city, we analysis the mainfunction of the natural ecological elements and basic characteristics, the thresholdeffect of the development of urban space and phase characteristics, analyzing theinteraction between the urban spatial layout and natural ecological elements, whichprovides a reality point to build a urban spatial layout theoretical system with naturalecological elements. Next come to the main part of our study. In this part, by studyingthe general methods of the hilly city spatial layout with natural environment elements,We tried to develop a mechanism for hilly city spatial layout with natural environmentelements, which consists seven aspects: the investigation and evaluation of currentecological status, the edge controlling of space development, the basic unit of spatialdivision, the construction of urban green open space, the selection of structure urbanmorphology, the optimization of urban road system, the adjustment of the layout ofurban functions. Lastly, we took the example of Anren county as the complementary of our theoretical study, proposed a macroeconomic framework and implementationmechanisms of the urban space layout.
