摘要
运用景观生态学的理论来认识城市灾害,分析了城市景观的基质、廊道对城市灾害的影响,运用斑块原理分析城市景观斑块的格局与城市灾害的关系。认为区域与城市景观基质在一定程度上控制城市灾害的类型;廊道是城市的灾害源、通道和承灾体;城市景观斑块,特别是灾害脆弱性斑块的格局特征对城市灾害的过程具有重要影响。在此基础上,以陕西榆林市为例,进行了以防灾减灾为目的的城市景观生态建设研究,并提出相应的生态建设建议。
This paper aimed to recognizing urban disaster by using theory of landscape ecology. It analyzed impacts of urban matrix and corridor on urban disaster. Using the principle of patch, the relationship between urban patch pattern and urban disaster was presented. It was concluded that regional and urban matrix controlled types of urban disaster to a certain extent; corridor was source, passage and bearing body of urban disaster; the characteristics of urban patch pattern, especially fragile patch's, had important influences on process of urban disaster. Based on the above work, taking Yulin City for example, ecological construction of urban landscape was studied in order to prevent and reduce urban disaster and some suggestions on ecological construction were put forward.
