摘要
采用全局空间自相关模型、Getis-Ord Gi*模型对中国31个省域的建设用地利用效率、农用地利用效率、土地利用综合效率进行分析。结果显示,三者均呈现空间集聚特征,建设用地热点区域面积小于农用地热点区域,建设用地热点区域与冷点区域面积仅占全部研究区面积的1/4,研究区半数省域属于土地利用效率无显著差异型。
Taking global spatial autocorrelation model and Getis-Ord Gi＊ model, to analyze construction land-use efficiency, agricultural land use efficiency and the comprehensive land use efficiency of 31 provinces in China. The results show that construction land-use efficiency, agricultural land-use efficiency and the comprehensive land-use efficiency present the characteristics of spatial clustering; the area of hot spot of construction land is smaller than that for agricultural land; the area of hot spots and cool spots only accounts for 1/4 of total regions; The study area half provinces belong to the land-use efficiency types without significant difference.
