摘　　要：运用DPSR评价模型构建生态安全评价指标体系,采用优劣解距离模型对经济后发型城市云浮市2011年—2016年生态安全状况进行评价。研究结果表明:(1)二氧化硫排放量、农业总产值、城市化水平赋权较大,对云浮市生态安全起重要作用。(2)驱动力、压力、状态、响应四个子系统的变化趋势有较大区别,压力与状态系统为城市生态安全水平提升提供重要保障。(3)云浮市生态安全状况整体呈上升趋势,2016年达一般安全水平,距安全水平还有较大差距。The DPSR model was used to construct the evaluation index system of ecological security.Based on TOPSIS method,this paper evaluates the ecological security situation of Yunfu city from 2011 to 2016,which has a slower urbanization development.The results showed that:(1)Sulfur dioxide emissions,agricultural output value and urbanization level were the three evaluation indexes which gave more weight to the ecological security of Yunfu city in the period of 2011-2016.It plays an important role in the ecological security of Yunfu city.(2)Driving force,pressure,state,response to the four sub-systems of the trend of change there is a big difference.The state and response system play an important role in the level of urban ecological security.(3)The overall situation of ecological security in Yunfu city is on the rise,reaching the general level of security in 2016.
