中文摘要	快速城镇化易引发各种生态问题,构建生态安全格局正是对生态过程的积极调控。为构建科学合理的生态安全格局,以内蒙古呼和浩特市为研究区,从自然环境、资源条件、人类干扰等角度构建区域用地扩展阻力评价指标体系,对城市区域空间管制进行了分区;通过最小累积阻力面(MCR)模型建立了区域生态安全格局,识别潜在生态廊道与生态战略点,构建区域生态网络框架,对生态空间进行规划。结果表明:(1)研究区生态安全格局类型区圈层式分布明显,较高安全水平以上的类型区占研究区总面积的22.47%,生态安全水平总体偏低。(2)共提取15条潜在生态廊道,识别7条一级生态廊道,9个生态战略点,进而优化点线面的生态安全格局。(3)生成一环、两带、两轴、多中心的生态网络框架,对于提升区域生境质量、提高生态服务价值及优化城市人居环境具有重要意义。结果发现研究区重点开发的乡镇有赛罕区、金河镇、小黑河镇,要引导城市重心向南部、东南部迁移,发展城市新区建设,引导人口、产业合理集聚。其结果可为生态环境治理提供理论参考。
英文摘要	A variety of ecological problems are caused by rapid urbanization,and the construction of ecological security pattern is the active regulation of ecological process.In order to build a scientific and reasonable ecological security pattern,taking Hohhot City as the study area,this paper built a regional land expansion index system in terms of natural environment,resource condition and human interference.Then this paper established a regional security pattern by MCR model,identified potential ecological corridors and strategical points,and constructed an ecological network framework,so as to partition the urban spatial control and make ecological spatial planning.The results show that:the type of circle distribution of ecological security areas is apparent.The areas with higher security level account for 22.47 percent of the total study area,which shows that the overall level of ecological security is low.There are 15 potential ecological corridors,7 firstclass ecological corridors,9 ecological strategic points in the study area,which optimizes the ecological security pattern of point,line and plane.The ecological network framework,the pattern ofone scope,two belts,two axes,and multi centers',is of great significance to upgrade the quality of regional habitats,promote the ecosystem service values,protect biodiversity and optimize urban human settlements.All results illustrate that the key zones for development are Saihan District,Jinhe Town and Xiaoheihe Town.It is recommended that the focus of urban be guided to move to the south and southeast.Besides,it should be developed the new urban areas,and conducted the rational agglomeration of population and industry.The results can provide theoretical reference for ecological environment management.
