摘　　要：生态安全是城市生态文明建设的主要目标,是城市经济可持续发展的重要基础,评价城市生态安全格局对于城市规划具有极其重要的作用。本文通过选取典型评价指标,运用生态安全格局客观分析法与主观分析法进行对比分析,建立了包括生态系统服务安全格局、生物多样性保护安全格局、生态敏感性安全格局的生态安全格局综合评价体系,并将该评价体系运用到研究区域,对研究区域生态安全格局的变化趋势进行评价和分析。结果表明:(1)在基本生态控制线内,低水平、较低水平生态安全格局区域的面积有所增加;在基本生态控制线外,中水平生态安全格局区域的面积有所减少;整体上高水平生态安全格局区域面积基本不变。(2)生态安全格局主观分析法评价结果主要依赖于专家的评定,本文采用的专家评价方法结果与客观分析法评价结果一致。该评价体系已经应用于研究区域的城乡规划和生态保护中,应用结果表明该评价体系能够较完备地进行城市生态安全格局评价,对城市规划和生态保护具有重要的指导作用。Ecological security is one of the main goals to the reconstruction of urban ecological civilization and an important foundation for the sustainable development of urban economy. Therefore, it is significant to evaluate the ecological security pattern of urban for urban planning. This paper selected several typical indexes, made a comparative analysis between objective analysis and subjective analysis method and established an evaluation system of ecological security pattern. To verify the effectiveness of the evaluation system, this paper made an evaluation of the ecological security pattern for the study area using the evaluation system. The result shows that： （1） The Tanglang mountain, Merlin mountain, Yinhu mountain, ecological corridors of Dashahe park and Xiangsilin park all have a low level of security pattern of the value of ecosystem service and ecological sensitivity. （2） The ecological corridors of Dashahe Park and Xiangsilin Park and the dams of Merlin and Changlingpi have a complete biodiversity with a low level of security pattern of the protection of biodiversity and ecological sensitivity. （3） On the basic line of ecological control, the area of the low level and lower level of ecological security pattern increased. Also, the area of the intermediate-level ecological security pattern had a decrease in the area outside the line. On the whole, the high-level ecological security pattern area was substantially constant. （4） The percentage of high level and intermediate level of security pattern is the same in the result made by taking the objective analysis method and the result by taking the subjective analysis method. The former percentage of low- level security pattern is less than the latter. In spite of the difference, they show the similar tendency and results.
