摘要:

通过构建“三生”功能综合评价指标体系,集成运用熵权法、层次分析法和地理探测器等方法,结合GIS空间分析,对2006—2018年黄河流域甘肃段57个县域“三生”功能进行综合评估,揭示其时空演化和分异特征,并定量识别其影响因素。结果表明:黄河流域甘肃段县域“三生”功能指数总体呈增强趋势,但空间差异较为显著,总体上沿黄河干流“玛曲-靖远”轴线较高而两侧相对较低;“三生”功能具有明显的空间正相关性,其中,生态功能集聚特征最为显著;“三生”功能均随时间变化,正相关类型集聚明显,呈“组团”式分布,负相关类型集聚性低,呈“零星”状的规律;城乡一体化水平是影响研究区“三生”功能空间分异的主导因素,且要素交互作用增强了“三生”功能的空间分异。

Abstract:

In order to reveal the spatial evolution and differential characteristics of the “production-living-ecological” function and quantitatively identify its influencing factors in 57 counties of Gansu Province in the Yellow River Basin, this paper comprehensively evaluates the “production-living-ecological” functionality of these counties during the period of 2006 to 2018 by the construction of an evaluation index system, the entropy weight method, the analytic hierarchy process (AHP) method, and geographic detectors. The results show that the functional index of “production-living-ecological” function in these counties shows an overall increasing trend, but the spatial difference is significant. The spatial pattern is higher along the mainstream of the Yellow River, i.e., “Maqu-Jingyuan” axis, and lower on both sides. The global Moran’s I index has proved that the “production-living-ecological” function in the research area shows an obvious spatial positive correlation, in which the characteristics of ecological function clustering are the most significant. In addition, the “production-living-ecological” function of the county’s changes over time, presenting a “group” type distribution of the obvious positive correlation clustering while a sporadic-like distribution of the low negative correlation clustering. It is found that in the study area, the urban-rural integration level of these counties is the main factor that affects the spatial differentiation of “production-living-ecological” function, and the interaction of different influencing factors enhances the spatial differentiation of “production-living-ecological” function.

Key words: human-land relationship, “production-living-ecological” function, geo-detector, the Yellow River Basin
