寒地滨水空间形态与生态关系关联及优化研究

Research on the Correlation and Optimization Strategy of Waterfront Spatial Form and Ecological Relationship in Cold Region

随着城市规模的扩张和对城市生态问题认识的逐渐深入,关于空间形态与生态关系之间的关系思考日益受到重视,着力于探求空间形态与街区外部空间生态关系的关联性。基于此,以大连市马栏河下游区段为例,分别确定空间形态特征及指标和生态因子特征及指标,通过实测所划分街区的生态数据,进行典型相关分析和皮尔逊相关分析,得到各指标相关程度的结果。在此基础上,从空间要素布局和生态关系调节两个层面提出寒地滨水空间的优化策略及马栏河下游区段的改造建议。

With the expansion of urban scale and the deepening understanding of urban ecological problems,people pay more and more attention to the relationship between spatial form and ecological relationship.The purpose of this paper is to reveal the relevance between spatial form and ecological relationship of external space.Based on this,the downstream section of Malan River in Dalian is taken as an example to determine the spatial morphological characteristics and indicators and the characteristics and indicators of ecological factors.Through the measured ecological data of the divided blocks,the canonical correlation analysis and Pearson correlation analysis are carried out to obtain the results of the correlation degree of each indicator.On this basis,the optimization strategy of waterfront space in cold regions and the transformation suggestions for the lower reaches of Malan River are proposed from two aspects of spatial factor layout and ecological relationship adjustment.
