土地资源紧缺倒逼建设用地使用由增量扩张向存量更新转型，加大存量用地更新改造力度已成为许多城市建成区优化功能、，提升品质的重要路径。而轨道交通线路及车站作为大城市中重要的空间联系纽带与节点，将成为城市建成区更新的触媒，产生“轨道＋”模式的多重更新效应。“轨道＋土地”将提高车站周边地区土地使用综合效益．“轨道＋环境”将提升城市环境品质，”轨道＋交通”将改善中微观出行环境，“轨道＋政策”将为车站周边地区的城市更新提供更强劲的动力，并搭建起更广泛、更有效的规划建设协商平台。本文以北京地铁国贸站的改造为案例，探讨“轨道＋”模式下城市更新的实施路径。

极端降水导致的暴雨洪涝灾害是陕西省第二大自然灾害,对社会稳定及经济发展造成了严重的影响。为明确极端降水风险,利用陕西省1969—2020年汛期(5—10月)的日降水数据构建极端降水量、极端降水频次、极端降水强度序列,选取6种极值概率分布模型对构建的序列进行拟合得到陕西省汛期极端降水最优概率分布模型;计算极端降水量以判断未来陕西省极端降水事件变化趋势;基于不同情景得到综合危险性空间分布,对陕西省极端降水综合危险性进行评估。结果表明:(1)Wakeby概率分布为最优概率模型,在3个极端降水指标序列中占比最多,且经过误差分析对比得到Wakeby分布函数是拟合陕西省汛期极端降水指标序列的最优概率分布模型。(2)计算不同重现期下的极端降水量与现有降水最大值进行对比,发现陕西省大多数地区发生小概率、高危险性的极端降水事件可能性增大。(3)陕西省汛期极端降水综合危险性整体从陕南至陕北呈南高北低分布,2 a、5 a、10 a、20 a、50 a、100 a一遇情景下危险区域各不相同。随着重现期的增加,低危险区逐渐消失,高危险区面积逐渐增大,100 a重现期下,高危险区面积占比从0增长至22.0%。研究结果可为陕西省极端降水概率分布研究提供参考,为汛期极端降水风险管理和评估工作提供理论依据。

Introduction Both China and France have a long history of urban and rural planning and governance, and lately the topics, such as urban and rural living quality, natural resources management, and natural and cultural heritage, have become the focuses of public policy that emphasizes improving people’s living conditions and promoting regional harmonious development. Moreover, the above topics have been regarded as the most important points in the bilateral cooperation agreements between China and France concerning sustainable urban development. On Oct. 13, 2019, the SinoFrench Seminar on "Meeting the New Challenges of Territorial and City Planning" was jointly held by the Department of Urban Planning, School of Architecture, Tsinghua University and the Cultural and Educational Cooperation Section, French Embassy–French Cultural Center in Beijing at the School of Architecture, Tsinghua University. About 20 experts from the political, academic, and professional fields of urban planning in China and France were invited to carry out discussion on four primary themes, which are "New Urban Planning Strategy,""New Territorial and City Planning Policy,""New Exploration in Urban Planning," and "New Talents Cultivation Pattern." As a medium support to the seminar, we collected some of the speeches and share them with readers in this issue.

针对目前电压暂降检测方法存在的的精确性低、实时性较差的缺点,提出了一种基于改进dq变换与顺序形态滤波器相结合的暂降检测新方法。研究论述了改进dq变换用于电压暂降检测的算法基本原理,介绍了顺序形态学概念,并由此基础设计了形态学滤波器,同时阐述了滤波器参数的选取方法。通过设置不同的信噪比与超前角度,仿真论证了新方法在理想条件和非理想条件下的暂降检测效果,并与传统方法进行了比较和分析。证明了新方法可以更高效精确地检测到暂降的特征值和起止时间。
