摘要: 本文以2003—2012年的土地利用数据、遥感数据等多源数据为基础,并且以街道作为研究尺度,通过不规则邻域CA和生态适宜性评价方法,制定城市扩张的弹性边界和刚性边界。研究表明:①基于不规则邻域CA模型的Kappa系数为0.875.8,模拟精度达到要求;②2021年研究区弹性边界的面积为230.54.km2,刚性边界的面积为260.09.km2,面积变化显著;③建设用地呈由东南向西北的扩张趋势,并且沿海街道比内陆街道扩张更为显著。

Abstract: Based on the data of land use data and remote sensing data from 2003 to 2012,this paper uses the street as the research scale to develop the elastic boundary and rigid boundary of urban expansion through the irregular neighborhood CA and the ecological suitability evaluation method.The following results were obtained:①The Kappa coefficient is 0.875.8 based on the irregular neighborhood CA model,and the simulation accuracy is required.②The area of the elastic boundary in the study was 230.54.km2,rigid boundary was 260.09.km2,and the area changed significantly.③The construction land shows a trend of expansion from the southeast to the northwest,and the coastal street is more significant than the inland street expansion.

Key words: urban growth boundary, irregular neighborhood, cellular automata, ecological suitability, Dalian Economic and Technological Development Zone
