闽江流域县域经济密度时空演变及影响因素
Spatiotemporal Evolution of County Economic Density and Its Influencing Factors in the Minjiang River Basin
摘要
Abstract
Clarifying the development status of county-level economies is fundamental to ensu-ring regional sustainable development.Taking 38 counties within the Minjiang River Basin as the study area,this paper constructs a comprehensive evaluation system of economic density based on per capita and per land area economic indicators,employs the entropy weight-grey model to measure county-level economic density,and analyzes its spatiotemporal evolution characteristics from 2012 to 2021 as well as its influencing factors.The results show that:(1)From 2012 to 2021,the overall county-level economic density in the Minjiang River Basin exhibited an upward trend,with the coef-ficient of variation increasing year by year,indicating gradually expanding internal disparities.(2)In 2021,there were 14 counties with medium-low economic density(36.84%),mainly distributed in the western part of the basin,and 15 counties with low economic density(39.47%),concen-trated in the northern part of the basin.(3)The local spatial autocorrelation of county-level econom-ic density was mainly characterized by high-high and low-low clusters,with the former remaining relatively stable,while the latter demonstrated a clear shift from north to south.(4)The number of health technicians(A2)was identified as the primary factor influencing county-level economic den-sity in the Minjiang River Basin(Q=0.458 3),and its interactive explanatory power with vegeta-tion coverage(NDVI,A4)was the highest(Q=0.937 3).关键词
