Study Of The Ecological Environment Effect On Construction Land Spatial Expansion In Shijiazhuang

Riverside landscape,as a scarce public resource in the city,plays an important role in human life,contains the values and aesthetics of the local people,and is the witness of urban development.Over a long period of time,with the rapid development of urbanization and industrialization,a large number of urban rivers are polluted and ecosystems are destroyed,which has a great impact on the riverside landscape and the environment and development of surrounding cities.Under this background,improving the hydrological quality,strengthening the ecological environment,increasing vegetation coverage and promoting the transformation of culture to landscape have gradually become a hot topic in all walks of life.This article combines the literature analysis,the spot investigation,the case inquiry,synthetically analyzes the Beizhi River present situation.And through questionnaire analysis,principal component analysis,IPA model and other methods to assess the landscape of Beizhi River,found that there are problems: ecological environment needs to be improved,cultural embodiment is weak,infrastructure is not perfect and so on.Based on the above problems,this paper uses the whole environment construction method to analyze the macro spatial layout and node distribution characteristics of Beizhi River,and divides the Beizhi River area into four aspects: boundary,matrix,patch and corridor,respectively,from the river ecological renovation,road,landscape node,building renewal and transformation,to explore the structure system of landscape optimization and upgrading at different scales.According to the results of the study,it can optimize the spatial texture and enhance the integrity of the riverside landscape by connecting the whole urban —— planning,locating the function of the riverside area and constructing the "whole part" design system.In the ecological aspect,the species diversity,the level of the branch river area is single,the building density is big,the vegetation coverage is low.In the cultural aspect,the architectural characteristic is missing,the architectural layout is chaotic,the cultural experience is insufficient.The introduction of regional culture and the transformation of ecological environment are the core of this study,which is one of the main methods to solve the lack of landscape and characteristics.
