摘要
为构建珠江流域高质量国土空间格局,推动上-中-下游协调发展。文章以主体功能区战略为切入视角,运用交叉转换矩阵和多尺度地理加权回归模型,对1990—2020年珠江流域“三区空间”演化特征与驱动机制进行分析。结果表明:1)近30年间珠江流域城镇空间剧烈扩张,生态空间微增,但农业空间大量减少,上-中-下游“三区空间”演化空间差异显著;全域农业空间面积大幅减少,主要在下游地区转换为城镇空间,在上、中游地区恢复为生态空间;2)不同主体功能区中,城市化地区城镇空间增长最为剧烈,生态功能区生态空间恢复显著,农产品主产区农业空间大量减少;3)珠江流域“三区空间”演化受社会经济要素、自然地理要素和道路交通要素的共同驱动,不同驱动因子对于不同类型空间演化的作用强度存在明显差异,其中,产业发展大幅推动了城镇空间的扩张,而生态环境保护政策有力地推动重点生态区地生态空间恢复。
Urban,agricultural,and ecological spaces,collectively referred to as the"three types of space,"are central elements in China's Territorial and Spatial Planning reforms.These spaces are crucial in bridging the National Main Functional Area Planning and regional coordinated development strategies at a higher level and in guiding land-use control at a lower level.The Pearl River Basin is one of China's most important economic development regions.This basin serves as a crucial region for the case study of evolution of the"three types of space."Understanding this evolution is critical for aligning regional land use with national strategic objectives and optimizing the coordinated development of these spatial elements.Using the National Main Functional Area Planning strategy as a starting point,this study applied a cross-conversion matrix and a multiscale geographically weighted regression model to analyze the evolution characteristics and driving mechanisms of the"three types of spaces"in the Pearl River Basin from 1990 to 2020.Three main results were obtained.First,over the past 30 years,urban space in the Pearl River Basin has expanded considerably,ecological space has slightly increased,but agricultural space has significantly decreased,with marked spatial differences in the evolution of the"three types of spaces"across the upper,middle,and lower reaches of the basin.Agricultural space has fully decreased across all reaches,converting to urban space in the lower reaches and reverting to ecological space in the upper and middle reaches.Second,within different national functional zones,urban space growth is most pronounced in urbanized areas,ecological space recovery is significant in ecological functional zones,and agricultural space has remarkably decreased in major agricultural production areas.Third,the driving factors for the different evolution directions of the"three types of spaces"in the Pearl River Basin vary.Industrial development has significantly driven the expansion of urban spaces,whereas ecological protection policies have effectively promoted the restoration of ecological spaces in key ecological areas.These findings effectively reveal the land-use evolution process in China's socioeconomic development regions over the past 40 years,highlight the risks and influencing factors of rapid urban space development and ecological space threats,and provide an important reference for optimizing land-use patterns in similar key regions of China.
