By constructing the evaluation system of construction land development equilibrium index,using the discrete coefficient method and cluster analysis method et al,the 14 cities in Gansu Province of the rationality of construction land development scale were analyzed and evaluated,and the causes of some cities imbalance were analyzed.The result showed that:Except the Lanzhou City ,the construction land development intensity of Gansu Province was no difference in the overall low level;the construction land supply capacity of the province with low levels of homogeneity;the equilibrium degree of Construction land development,from high to low in order was Hexi region,southeast region,middle region;the reason of imbalance was that take Lanzhou as the center to the southeast and northwest show the pattern of excessive development-serious lack of development and insufficient development;the most balanced cities for the development and utilization of construction land were Jinchang and Jiayuguan,and the seriously unbalanced city was Dingxi.The rationalization proposal were put forward:For over developed cities,we need to control the land use scale and efficiency,and attempt reducing development;and for the less developed cities,we could guarantee the development of cities in two aspects of scale and efficiency.%构建了建设用地开发平衡指数评价体系,采用离散系数法、聚类分析法等评价甘肃省14个市(州)的建设用地开发规模的合理性,对部分市(州)失衡的原因进行了分析.结果表明:甘肃省建设用地开发强度除兰州市外,整体低水平无差异,建设用地供给能力全省具有低水平同质性,建设用地开发平衡度河西地区-陇东南地区-中部地区递减;失衡原因为以兰州市为中心向东南与西北方向表现出开发过度-开发严重不足-开发不足的空间格局;建设用地开发利用最平衡城市为金昌市、嘉峪关市,严重失衡城市为定西市.提出平衡化建议:对于过度开发城市的土地利用需"控制规模,提升效率",尝试减量化发展;对于开发不足城市,可从规模和效率两方面保障城镇发展.
