摘　　要：为科学认识嘉陵江流域“三生空间”时空演化过程和耦合协调特征,揭示嘉陵江流域“三生空间”时空演化的影响因素,通过构建“三生空间”分类及功能评价体系,采用土地利用转移矩阵、耦合协调模型,揭示了1990—2020年嘉陵江流域“三生空间”时空分布和演化过程及耦合协调程度,并借助PLUS模型对“三生空间”动态演化影响因素进行定量识别。结果表明:(1)嘉陵江流域“三生空间”整体和县域格局时空动态演化明显,1990—2005年和2005—2020年流域整体“三生空间”综合动态度分别为0.10%、0.99%,1990—2020年生产、生活、生态空间发生动态变化的县域占比分别为79.82%、96.33%、62.39%;(2)“三生空间”相互转移较为剧烈,生产空间呈缩减态势;生活、生态空间扩张明显;(3)生产、生活空间分布和扩张地区的耦合协调水平均较高,生态空间主要分布地区的耦合协调水平相对较低;(4)以农田生产潜力、平均坡度及NDVI为主的自然因素决定了“三生空间”的整体布局,人口密度、农村居民人均可支配收入、公共财政支出及地区GDP等社会经济因素控制着“三生空间”的演化速度与方向。嘉陵江流域“三生空间”分布呈明显极化特征,转移动态演化明显,自然和社会经济因素共同影响着“三生空间”的分异格局和演化过程。To scientifically understand the spatio-temporal evolution process and coupling coordination characteristics of“Production-Living-Ecological Space”in Jialing river basin and reveal its influencing factors as well,the classification and function evaluation system of“Production-Living-Ecological Space”is constructed,and land use transfer matrix and coupling coordination model are employed to reveal the spatio-temporal distribution,evolution process and coupling coordination degree of“Production-Living-Ecological Space”in Jialing river basin from 1990 to 2020.In addition,the influencing factors of the dynamic evolution are quantitatively identified with the help of PLUS model.The results are as follows:(1)The overall spatio-temporal dynamic evolution of“Production-Living-Ecological Space”and the county pattern in Jialing river basin was obvious;the comprehensive dynamic degree of“Production-Living-Ecological Space”in Jialing river basin was 0.10% from 1990 to 2005 and 0.99% from 2005 to 2020,and the proportions of counties with dynamic changes in production,living and ecological space were 79.82%,96.33% and 62.39%,respectively.(2)The mutual transfer of“Production-Living-Ecological Space”was more intense;the production space had shown a trend of reduction;while the expansion of living and ecological space was obvious.(3)The coupling coordination level of the distribution and expansion areas of production and living space was higher whereas the coupling coordination level of the main distribution areas of ecological space was relatively lower.(4)The overall layout of“Production-Living-Ecological Space”was mainly determined by natural factors such as farmland production potential,average slope and NDVI while the evolution speed and direction of“Production-Living-Ecological Space”was controlled by socio-economic factors such as population density,per capital disposable income of rural residents,public financial expenditure and regional GDP.The distribution of“Production-Living-Ecologica
