【摘要】：基于广州市环境保护信访事件、人口普查、社会经济统计等数据,利用标准差椭圆、核密度函数等方法分析2011~2015年间广州市环境保护信访事件数量和空间分布变化特征,得出主要结论如下:第一,与2011年相比,2015年信访事件数量增加了366%。空气污染、噪声污染、其他事项和水污染是最主要的环境保护信访事件类型。第二、三产业是引发信访事件的主要国民经济产业类型。第二,广州市环境保护信访事件的整体格局从中心城区集中分布模式向全市范围内均匀分布模式转变,并呈现出明显的"南拓和东进"特征。第三,据此建议政府应在摸清广州市域内各污染源所排放的各类污染物质的种类、数量及时空分布特征的基础上制定控制污染的最佳方案,并针对热点区域进行重点监控。
[Abstract]:Based on the data of environmental protection letter and visit events, population census, social and economic statistics in Guangzhou, the number and spatial distribution of environmental protection letters and visits in Guangzhou between 2011 and 2015 were analyzed by using standard deviation ellipse and nuclear density function. The main conclusions are as follows: first, compared with 2011, the number of letters and visits on 2015 increased by 3666.Air pollution, noise pollution, other matters and water pollution are the most important types of environmental protection letters and visits. The third industry is the main type of national economy industry that causes the petition event. Second, the overall pattern of the environmental protection letter and visit event in Guangzhou has changed from the centralized distribution mode in the central urban area to the uniform distribution pattern in the whole city. And it shows obvious characteristics of "southward extension and eastward advance". Thirdly, it is suggested that the government should find out the types of pollutants discharged by various pollution sources in Guangzhou. Based on the characteristics of quantity and time-space distribution, the best scheme of pollution control is established, and the focus of monitoring is focused on hot spots.
