黑龙江省资源型城市环境污染水平时空格局演化特征及驱动因素研究

Research on the Evolution Characteristics and Driving Factors of the Spatio-temporal Pattern of Environmental Pollution Level in Resource-based Cities in Heilongjiang Province

以黑龙江省资源型城市为研究对象,利用2005~2017年环境质量数据指标构建环境污染水平评价体系,采用重心迁移、空间地理加权回归等方法对资源型城市的环境质量展开研究.结果表明:各资源型城市环境质量平均指数为0.125,鸡西市环境质量在研究期内处于全省较高水平.2015~2017年黑龙江省各资源型城市环境质量指数从总体上看,鹤岗市、牡丹江市、鸡西市、双鸭山市的环境质量指数波动较大.在环境质量指数的空间分布上,研究期内大庆市环境质量逐渐改善.黑龙江省资源型城市环境质量重心主要分布在佳木斯西南部、七台河东北部以及佳木斯中部.资源消耗、社会发展、经济增长、创新驱动对各个资源型城市环境质量有非常重要的影响.

Taking the resource-based cities in Heilongjiang Province as the research object, using the 2005~2017 environmental quality data indicators, an environmental pollution level evaluation system is built. Using methods such as center of gravity migration and spatial geographic weighted regression, the environmental quality of resource-based cities is studied. The results show that: The average environmental quality index of resource-based cities was 0.125, and the environmental quality of Jixi City was at a relatively high level in the province during the study period. From 2015 to 2017, the environmental quality index of various resource-based cities in Heilongjiang Province, as a whole, fluctuated greatly in Hegang City, Mudanjiang City, Jixi City, and Shuangyashan City. In terms of the spatial distribution of the environmental quality index, the environmental quality of Daqing City has gradually improved during the study period. The center of environmental quality of resource-based cities in Heilongjiang Province is mainly distributed in the southwest of Jiamusi, the northeast of Qitaihe and the middle of Jiamusi. Resource consumption, social development, economic growth, and innovation drive have a very important impact on the environmental quality of various resource-based cities.
