1城市水体对热岛的缓冲性能沿河岸距离的变化规律显示文摘城市水体包括城区内的自然水体和人工水体两大类。作为城市生态系统的重要组成部分,水体在缓解城市热岛效应(Urban Heat Island,UHI)上具有重要作用。研究城市热岛效应的现状,探讨水体对城市热岛的缓冲效应,为改善城市热岛效应和生态环境,并对城市进行合理的改造和规划提供理论依据。以长沙市中心城区为研究区域,以南北向贯穿长沙市的湘江河道作为主要研究对象,基于长沙市2016年7月Landsat 8 TIRS遥感影像采用大气校正法反演地表温度(Land Surface Temperature,LST),利用监督分类法获取其同步的城市化进程和土地利用类型,分析市区内地表温度及热岛效应的空间分布特征。同时,通过在湘江两侧建立多个尺度的缓冲区,并将其与地表温度分布及土地利用类型叠置,分析湘江为主的水体对长沙市热环境及各缓冲区的缓冲效应,结果表明:(1)长沙市城市建设格局与热岛效应空间分布基本相似,建筑用地热岛效应更高,极端地表温度达到53.8℃;水体、绿地和裸地的热岛效应相对较低,最低地表温度为16.0℃;(2)湘江对长沙市热岛效应具有缓冲作用,对长沙市热岛效应的平均缓冲距离为400 m;(3)湘江对热岛效应的缓冲能力与水体周边土地利用类型有关,对河东区的缓冲作用小于河西区,对沿江休闲区的缓冲效应大于沿江住宅区。综上所述,长沙市热岛效应强度与用地类型相关,建筑用地热岛效应严重;水体对热岛的缓冲效应显著,但不同缓冲区内缓冲距离存在差异,因此对城市生态格局进行小规模改造可增强水体缓冲作用,缓解城市热岛效应。曾素平 时琢 赵梅芳 刘发林 王光军 林杨 李沁园 向枝远 陈小伟 U.S Ogbodo 2020生态学报2020,40,15:14

13Decentralized Control for a Class of Similar Composite Systems with Interconnections with Unsatisfying Interconnection Condition显示文摘In this paper, a class of similar composite systems is discussed, whose interconnections are asymmetrical and mismatched. The interconnection condition is proposed. Based on it, the interconnections are divided into two parts. One satisfies the interconnection condition, by means of the two-step method, the decentralized controllers are designed. The other does not satisfy the interconnection condition, but this is offsetted by good quality of the system itself. Based on these, a sufficient condition is given by some linear matrix inequalities, which makes the studied systems quadratic stabile via linear decentralized controllers by making use of the information of interconnections better.WANG Zheng1, LI Zhong hai1, ZHANG Si ying1, HOU Xue\|zhang2 1.School of Information Science and Information Engineering, Northeastern Unviersity, Shenyang 110006, China 2.Mathematics Department, Towson University, Baltimore, Maryland 21252, U.S 2001Journal of Systems Science and Systems Engineering2001,13,1:0
