Research On The Space Pattern Planning Of Shenfu New Town According To Ecological Security Patterns

With the rapid development of urbanization,population expansion and the construction land expansion inevitably brings the huge pressure to natural resources and ecological environment,resulting in the emergence of a series of ecological security problems.Through effective planning means to guarantee the urban ecological safety in the expansion has became the problems urban development must be taken into account.The ministry of construction,to solve these problems,reflect on the disadvantages of traditional planning method.The new Urban-rural planning law and urban-rural planning formulation which successively promulgated,have a series of significant changes to the original planning method system.But so far,both in theoretical research,technology practice or policy level,the research for the r space control in the urban planning is scattered and one-sided,and haven't formed a complete system.The study on practice is also insufficient and the overall research is relatively weak.On the basis of thorough analysis of urban ecological security?urban ecological security pattern,summarizes the domestic and foreign relevant theory and practical experience,from solving the contradictions,fast urban development faced,between ecological protection and city construction,put forward planning based on urban ecological security pattern.Based on empirical study case of Fuxin city:Firstiy,based on the Shenfu new town ecological environment present situation analysis and evaluation,acco rding to the main ecological problems which influence the development of Fuxi n,selection of ecological bottleneck factor,take the factor of ecology theory,ecol ogical sensitivity analysis method,based on the GIS technology and the ecologi cal sensitivity evaluation of the bottleneck factors,construct a sustainable ecologi cal security pattern.Secondly,according to the "negative planning "theory,com bined the level of urban ecological security pattern evaluation,and get to spac e control division for the purpose of protecting the city ecological security.Thi rd,combined the result of the space control division with the ecological functi on regionalization,according to the ecological service function.Finally,put for ward concrete Suggestions to Guarantee the implementation of planning.
