摘　　要：随着城市化进程的推进以及人口的持续增加,对城区大量的土地资源进行开发建设,导致出现土地资源匮乏的问题。为更好辅助城市规划、经济建设、社会发展以及环境保护等方面,本文以大连市主城区为例,基于DEM图像与相关数据,运用MapInfo和ArcGIS地理信息系统平台,建立覆盖大连市主城区全域的50 m×50 m面状矢量格网,作为地形分析的基础格网,对大连市主城区地形进行海拔高程和坡度分析。以海拔高程60 m,坡度25%为基准统计大连市主城区不受地形因素制约的可建设用地区域。在将主城区划分为可建设用地区域与限制建设用地区域的基础上,统计各市辖区的可建设用地区域所占比例和面积。从整体上看,可建设用地区域占整个主城区的50.034%,其中中山区、西岗区、沙河口区、甘井子区的可建设用地区域比例依次为50.561%、64.509%、73.570%、45.679%。为使统计结果更好地支持对大连市开发建设的研究,进一步对各街道可建设用地区域进行统计分析。With the advancement of urbanization and the continuous increase of population,the development and construction of a large number of land resources in urban areas lead to the problem of lack of land resources.In order to better assist the urban planning,economic construction,social development and environmental protection,this paper takes the main urban area of Dalian as an example,based on DEM images and relevant data,and uses MapInfo and ArcGIS platform to build a 50 m covering the whole area of the main urban area of Dalian As the basic grid of terrain analysis,50 m area vector grid is used to analyze the elevation and slope of the main urban area of Dalian.Based on the elevation of 60 m and the gradient of 25%,the constructable land area in the main urban area of Dalian,which is not restricted by the topographic factors,is calculated.On the basis of dividing the main urban area into the construction land area and the restricted construction land area,the proportion and area of the construction land area in each municipal area are calculated.On the whole,the construction area accounts for 50.034%of the total urban area,among which the construction area proportion of Zhongshan District,Xigang District,Shahekou District and Ganjingzi District is 50.561%,64.509%,73.570%and 45.679%respectively.In order to make the statistical results better support the research on the development and construction of Dalian City,further statistical analysis is made on the construction area of each street.
