摘　　要：不断涌现的削山造城工程引发了广泛的议论,但严谨的研究论证却难得一见。系统地研究这一问题:第一,回顾中国城市化的历史和城市化政策的演变,指出部分城市空间不足和更符合经济规律的城市化政策的实施是发生削山造城的背景;第二,通过对城市形状理论和城市规模收益理论的系统研究,提出有效主城区的概念,从理论上指出,地形限制导致有效主城区规模不足是削山造城发生的根本原因;第三,使用Google Earth软件逐一考察了全国地级以上城市的形状、地形,指出全国有1/4的城市有削山造城的需要;第四,通过研究无地形限制的城市有效主城区面积如何受相关因素影响,得出了确定削山造城合理规模的公式;最后提出了相应的政策建议。This paper studies the continuing hill-cutting practices in city construction.First,a review of the city history in China shows that space constraints and the implementation of urbanization poliey which is more consistent with economic law are the background of cutting hills.Second,analysis of city shape theory and city scale income leads to a new concept-efficient main urban district,which tells that the insufficient of efficient district is the main reason for cutting hills.Third,the shape and topography of cities collected by Google Earth show that one fourth of the district-level cities need to cut hills around them.Fourth,by studying how the area of efficient urban district is affected by the related factors,statistical study yields a formula to determine the optimal volume of cutting hills Finally,policy advices are given accordingly.
