Abstract


Ecological corridor in the city (ecological corridor) effective series of ecological island, and the formation of a continuous urban ecological space and enhance the stability of the ecological space. The ecological corridor morphological urban ecological planning need to be considered and the basis for the content. Past domestic scholars quantitative description of the morphology of urban ecological corridor has been less involved. Digital Planning combination of traditional urban planning theory and modern science and technology, IT, and gradually form a quantitative theory of urban planning and technical methods in practice. The digital planning concept has been widely accepted and is becoming a hot research topic. Coupled with the current field of planning rarely GIS as a planning and design analytical tools to use Therefore, this study was to explore the morphology of the urban ecological corridor proposed the morphology of urban ecological corridor quantitative description of indicators, and the formation of a GIS-based urban ecological Gallery Road quantitative description of the morphology and the calculation method. On the basis of previous ecological study of the urban landscape and urban planning digitizing method, the core of this study is to establish a quantitative analysis of urban ecological corridor morphological indicators. The paper consists of introduction, the ecological corridor Theory of ecological information of features preprocessing methods, morphological characteristics of urban ecological corridor quantitative description of cities at home and abroad ecological corridor morphology five parts. Isolated under the premise of the ecological feature graphical information by satellite images collected by the city feature information pretreatment, application of existing GIS application software, according to the form of the basic characteristics of the ecological corridor, eigenvalue calculation. By induction the value of the basic characteristics of these forms, the ecological corridor summarized and divided into three forms of linear, massive and banded. Ecological corridor is a massive and banded planar ecological corridor areas. The proposed the ecological corridor density, node density, abundances seven urban ecological corridor morphology study quantitative description of the indicators reflect the main features of the urban ecological corridor form the 7 morphological indicators from three aspects. The application of these indicators quantitative calculation of foreign urban ecological corridor morphology. Quantitative indicators calculation results based on ecological corridor morphology in Chinese and foreign cities, summarize the significant difference between domestic and international urban ecological corridor 6. Through domestic and international cities unique geographical, cultural and other factors, the authors explore the causes and results of the ecological corridor morphological differences of cities at home and abroad. The foreign urban ecological corridor morphological quantitative comparison of the results not only reflect the differences between the urban ecological corridor morphology, the ecological corridor morphological quantitative indicators rationality, but also reflect the domestic urban ecological corridor morphology optimized way. Quantitative analysis indicators, thus of the ecological corridor morphological proposed based GIS urban morphology the ecological corridor reasonable planning morphological numerical reference for domestic cities.
