摘　　要：研究基于景观安全格局理论、高分辨率遥感影像、GIS和RS技术,以苏南地区常熟市辛庄镇为例,从景观类型、建设密度、生态价值、生态适宜性和生态敏感性等5个方面建立城镇扩展的阻力因子评价体系,运用最小累积阻力模型计算研究区城镇空间扩展过程需要克服的综合累积阻力,在此基础上基于阻力阈值将研究区划分为优先建设区、适宜建设区、限制建设区和禁止建设区4个等级,最终形成辛庄镇城镇扩展的生态安全格局,进而确定了辛庄未来空间增长的合理规模与发展方向,以期为研究区未来的城镇总体规划、土地利用总体规划提供科学参考。Based on landscape security pattern theory,high-resolution remote sensing image,GIS and RS technology,taking the Xinzhuang town of Changshu city in the south of Jiangsu province as a case study,the author used minimum cumulative resistance model to calculate cumulative resistance needed overcoming during the process of urban land expansion,from resistance factor evaluation system consisting of landscape types,building density,ecological value,ecological suitability and ecological sensitivity.Then,based on the resistance threshold,the study area was divided into four classes zones： preferred,suitable,confined,and strictly prohibited areas,which were 2624.48hm 2,1293.92hm 2,1790.44hm 2,4717.16hm 2,respectively.The ecological security pattern was established to decide the reasonable direction and scale of urban growth of Xinzhuang town with ecological security,and expected to provide a scientific basis for the future urban planning and land use planning.
