Research On Accessibility Of Public Green Space Landscape In Changchun High Tech Zone Based On GIS

With the economic development of society,the living standard of the public has been continuously improved.Meanwhile,the quality of life is also climbing.As a result,higher demands are required on urban ecosystems.Therefore,improving the urban ecosystem has become a new task in the new period.Under such context,the concept of green-land accessibility was introduced from previous exploration and research,and evaluation was built by analyzing the influencing factors modelling of accessibility.Changchun High-tech Zone is currently under the process of development and construction with suitable constructing conditions.Public green landscape construction is better than the old-city zone,however,it does not lead to good living experience to the residents.Therefore,the analysis and research of the feasibility of the public green landscape in the High-tech Zone of Changchun City is of great importance and significance.Under such this research topic,to begin with,the relative concepts and basic theories are specifically explained and defined,and relevant researches on domestic and international feasibility and the factors influence public green landscape accessibility and evaluation methods are combed.The research method on urban public green landscape accessibility are summed up,and the experience achieved from summarizing them and the influencing factors and evaluation methods are comprehensively considered and compared.Secondly,regarding the public green landscape of Changchun High-tech Zone as the research object,the spatial accessibility,pedestrian accessibility as well as accessibility of bicycles,vehicles Were analyzed.The results using GIS network analysis method indicates that the traditional green space index in the High-tech Zone is relatively high with low accessibility;the perfect vehicle transportation system greatly increases,but it is seriously slowing down the accessibility of the public green landscape.The west of the Hi-tech Zone is the main service blind area,additionally,the ratio of supply and demand are not perfectly balanced;Finally,according to the analysis results,we can formulate optimization strategies by improving the public green landscape spatial system as well as road traffic system,guiding the land use planning can also contribute to the strategy.The research on the optimal accessibility of public green space landscape obtained from the final research has a certain theoretical guiding significance for the construction of high-tech zones,it also enjoys a reference significance for the study of related directions.
