随着社会的进步和发展,城市的规模也在壮大,城市管理方面也面临了严峻挑战。CIM(City Information Modeling)平台,又称城市信息模型平台,具备多源异构数据融合能力、多维度空间分析能力、大数据分析计算能力和多终端支持能力。是提升城市管理质量和城市管理模型创新中的核心平台,近年来,行业内专家和学者对CIM平台进行了大量的研究工作,且CIM平台的建设要求已纳入国家“十四五”规划。CIM平台可为城市从规划、建设、管理、治理到运营的闭环业务场景提供技术保障,是推动城市治理体系和治理能力现代化的必然选择。

保泰松治疗游走性栓塞性静脉炎初步报告

中华皮肤科杂志 1965年第6期11卷 375-375页

作者： ge guanying YU Yongkang 上海市杨浦区中心医院皮肤科上海市杨浦区中心医院皮肤科

制法:用碗一只,碗口上糊一层结实的纸,用针在纸上刺满孔,将木屑放在纸上,用一小块红炭放在木屑上烧,使木屑出油,滴入碗中。至将烧近纸时,应立即把烧焦的木屑全部去掉。不让木屑灰掉入碗中。取油抹患处。

以济南市历下区14个街道为例,运用GIS技术的缓冲区分析以及服务区分析法,基于城市道路网、居民居住区点和中小学点位数据,分析济南市历下区59所小学与27所中学的服务覆盖范围和空间可达性。结果表明:历下区总体中小学配置较为合理,学校空间覆盖度与可达性成正相关,由西部主城区向东中小学校的覆盖度与可达性逐步降低,靠近主城区的大明湖街道、解放路街道等中小学覆盖居民区范围较大、可达性较好,智远街道、舜华路街道等中小学覆盖居民区范围相对较小、可达性较差。
