摘要
本研究构建了福建省泉州市"压力-状态-响应"模型,利用层次分析法(Analytic Hierarchy Process,AHP)对模型涉及的29项指标进行权重赋值,通过指标标准化处理以消除指标之间量级和单位的差异.结果表明:1)2018-2022年,人口和建成区面积不断扩大,生态压力不断加大;2)通过提升表征系统状态指标方面的投入,提高绿地面积比例、工业固体废弃物综合利用率、污水处理率、第三产业占比等,生态环境质量呈改善态势;3)生态压力和生态响应呈现"此消彼长"关系,尤其是2020年前后最为明显(可能和疫情防控等因素有关);4)通过系统性的指标分析,泉州市经济社会发展处于平衡状态,区域承载力指数从-0.047上升到0.035.本研究对于区域经济社会可持续发展具有重要作用,保障区域经济社会可持续发展,需要不断加大表征系统状态方面指标的投入.
Abstract
This study established a"pressure-state-response,PSR"model in Quanzhou City,Fujian Province.The weights of 29 indexes were calculated by using Analytic Hierarchy Process(AHP).In order to eliminate the influences from the units and ranges of the indexes,each of the 29 indexes was standardized by subtracting the mean and dividing by the stand deviation.The results showed that:1)The population size and built-up area expanded and the consumption of resources increased from 2018 to 2022,representing the enhanced ecological pressure.2)By investing on the indexes of system state,such as the sewage treatment,the proportion of the tertiary industry,and the urban grassland,the environment quality displayed positive reply.3)The relationship between ecological pressure and response shows a"trade-off"relationship,especially around the year 2020(possibly resulting from the severe social control of 2019-nCoV epidemic).4)The development of Quanzhou City is balanced and the regional ecological carrying capacity index has increased from-0.047 to 0.035.To ensure the sustainable development of regional economy and society,it is necessary to increase the investments on the indexes of system state.This study is meaningful in analyzing the sustainability of regional economy and society.
