城市化对北京一次极端降水过程影响的数值分析   总被引：3，自引：1，他引：2  

郑祚芳  高华  李青春 《气象》2013,39(3):340-346

通过敏感性试验探讨了城市化对北京2011年6月23日局地极端降水事件的影响.结果表明耦合了城市冠层模式的WRF系统能较好地模拟出强降水的局地性和突发性特征,考虑了精细下垫面分类的敏感性试验模拟降水更接近实况;下垫面城市化对地表能量平衡影响明显,对大气的热量影响除加强地表对边界层大气向上感热输送外,还会减少局地地表蒸发及大气水分供应,增加边界层高度,并对移经本地的天气系统强度及水汽输送产生较明显的影响.  相似文献   

基于多源数据的城市热岛效应研究——以石家庄地区为例   总被引：3，自引：1，他引：2  

杨鹏  陈静  侯晓玮  高祺  赵强 《气象》2013,39(10):1304-1313

以石家庄地区为研究对象,选取地面气象观测站数据、区域自动站数据、MODIS 1B以及Landsat7 ETM+卫星遥感影像数据作为主要数据源,从气温和地表温度两个角度考虑,分析城市化进程对城市热岛效应的影响,城市热岛的时间变化规律以及空间分布规律等。研究结果表明：(1)石家庄城市热岛强度随时间逐年增加且呈继续上升趋势,与城市化进程呈同步变化趋势;(2)采用同一时次气温和地表温度资料分别研究石家庄城市热岛空间分布特征,发现夏、秋季白天和四季晚上石家庄城市热岛效应明显,春、冬季白天有时出现“冷岛”效应;(3)与白天相比,在晚上气温和地表温度两者的相关性较好,其相关系数可达0.80;(4)选用Landsat7 ETM+高分辨率卫星遥感影像数据研究不同土地覆盖类型对城市热岛的影响,发现地表温度随着植被指数NDVI的增大而减小,两者之间呈现很好的负相关性,R2=0.72。  相似文献   

太原城市化进程对城市热岛的影响     

李艳红  赵彩萍  李玉琴  周晋红 《气象科技》2013,41(2):360-364

采用城市化的多项要素指标,系统考察了太原1980-2009年期间城市化的发展对其城市热岛效应的影响关系,发现城市化的发展是导致城市热岛效应形成和加剧的主要原因.认为:①近30年,太原市郊区的增温率为0.51℃/10a,市区的增温率为0.90℃/10a,热岛强度的增温率为0.39℃/10a,热岛效应不断增强;②各类城市发展指数与城市热岛效应都有很好的相关关系;③太原城郊温差和总人口对数呈线性相关关系,其长期变化相关系数为0.81;④太原城郊温差和城市房屋建筑面积对数呈线性关系,其长期变化相关系数为0.85.  相似文献

归一化光谱分解模型在城市化信息提取中的应用     

马勇刚  李宏 《地理空间信息》2012,10(4):40-41,44

以2001年7月11日LandsatETM7影像和2009年7月16日TM影像为数据源,基于V-I-S理论模型,采用归一化光谱分解模型提取了乌鲁木齐市区范围内2个时段的植被、土壤、不透水层3个连续地表参数分量。通过对不透水层不同阈值的划分,提取了2时段的乌鲁木齐市城市发展的空间信息,结果较为满意;通过空间叠加计算方式获取了8年来乌鲁木齐市城市化发展的空间信息和主要拓展方向。结果表明,乌鲁木齐城市化发展速度较快,特别是北扩趋势显著。  相似文献   

塔里木河中下游城镇化进程中水资源利用分析   总被引：3，自引：0，他引：3       下载免费PDF全文

王长建  张小雷  杜宏茹  李雪梅 《干旱区地理》2012,35(2):324-331

 基于2000-2008年的统计数据,通过比较和定量分析塔里木河中下游巴音郭楞蒙古自治州（以下简称巴州）各县市城镇化水平与用水总量、用水效益、产业结构和用水结构的变化过程,建立城镇化水平与用水效益、用水总量之间的数学关系。结果表明：巴州各市县的用水效益都在不断提高,基本上是城镇化水平越高的地方其用水效益也高。城镇化水平与用水效益呈线性增长关系,巴州整体城镇化水平的提升对用水效益的增加有较大影响,城镇化水平提升一个百分点,用水效益增加2.62 元/m3。巴州的城镇化水平与用水总量之间对数增长关系不明显,水资源对城市化进程存在明显的约束作用。今后需要促进产业结构优化升级,提升水资源开发利用水平,提高用水效益,促进城镇化发展与水资源开发利用呈现出城市化水平高、用水总量低、用水效益高的高水平协调状态。  相似文献   

南疆铁路沿线地区城市化与土地利用相关分析     

孜比布拉·司马义  帕夏古·阿不来提  苏力叶·木沙江 《中国沙漠》2012,32(1):264-269

 以南疆铁路沿线的5个中心城市为基本单元,根据1993—2008年的城市化与城市建设用地结构方面的数据,分析了5个中心城市的城市化与城市建设用地之间的相关性。南疆铁路沿线5个中心城市目前的平均城市化率为48%,已进入了快速城市化发展阶段。研究结果表明,随着城市化的发展,城市建设用地结构也发生相应的变化。在用地结构中,居住用地、工业用地比例降低;公共设施用地、道路广场用地、绿地比例增加,仓储用地、对外交通用地和特殊用地比例呈现基本稳定趋势。城市建设的不断完善、城市化率的提高是促进建设用地结构变化的主要因素。  相似文献
