Coupling coordinated development among digital economy,regional innovation,and talent employment:A case study in the Hangzhou Metropolitan Circle,China

Coordinative development across various systems,particularly the economic,social,cultural,and human resources subsystems,is a key aspect of urban sustainability and has a direct impact on the quality of urbanization.The Hangzhou Metropolitan Circle,comprising Hangzhou City,Huzhou City,Jiaxing City,and Shaoxing City,was the first metropolitan circle approved by the National Development and Reform Commission(NDRC)as a demonstration of economic transformation in China.To evaluate the coupling coordination degree of the four cities and analyze the coordinative development in three systems(including digital economy,regional innovation,and talent employment),we collected panel data during 2015–2022 from these four cities.The development level of the three systems was evaluated by the standard deviation method and comprehensive development index.The results are as follows:(1)the level of coupling coordinated development of the three systems in the Hangzhou Metropolitan Circle was relatively low;(2)the coupling coordination degree of the four cities in the Hangzhou Metropolitan Circle showed significant regional differences,among which Hangzhou City was in the leading position,and Huzhou,Jiaxing,and Shaoxing cities made steady but slow progress in the coupling development of the three systems;and(3)the development of digital economy and talent employment needs to be strengthened.This study contributes to the coordinative development of Hangzhou Metropolitan Circle by innovatively focusing on the coupling coordination relationship among digital economy,regional innovation,and talent employment,which also meets the industrial layout of Hangzhou Metropolitan Circle.In this way,the optimal allocation and sustainable development of digital economy,regional innovation,and talent employment in the Hangzhou Metropolitan Circle can be achieved.

Land Surface Temperature Change in Hangzhou Urban Area in Recent 20 Years Based on Landsat Image

Since the reform and opening-up in 1978, the urbanization level of our country has been continuously improved and the urban development has made great progress. However, with the rapid expansion of urban construction land, the population density and building density have been greatly increased, resulting in the urban heat island effect, which has negative impact on the urban thermal environment and restricts the high-quality development of urbanization. This paper focuses on how the urban surface thermal environment of Hangzhou changes in 20 years. In this paper, the characteristics of land surface temperature (LST) in Hangzhou urban area from 2000 to 2020 were studied by using Landsat images. The radiative transfer equation method is used to retrieve the land surface temperature, and the retrieval results are analyzed. The results show that: 1) the land surface temperature in Hangzhou city area has a slight upward trend in the past 20 years;2) the area of high temperature area is expanding;3) the land surface temperature in the city center area has decreased significantly in the past 20 years, while the ground temperature in other areas around the city center has increased significantly.

基于遥感的海域环境变化监测分析

以杭州湾海域和连云港周边海域为研究对象,基于Landsat-5、Landsat-9的多光谱和热红外数据,对研究区的海域岸线和温度场信息进行提取,分析海域岸线变迁和温度分布变化特征。结果显示,研究区的海域岸线变化均较显著;海域温度在核电站运行前较为均匀,无明显温度分异,核电站运行后,因温排水排放,核电站周边海域温度出现明显分异;Landsat-9热红外数据温度反演结果可靠,可用于监测温排水对海域环境的影响。

杭州湾北岸现代潮滩沉积物粒度特征及其对古海平面的指示意义

对杭州湾北岸3处现代潮滩沉积物进行高精度粒度分析,查找研究区潮滩不同微相的粒度特征和差异,提取基于粒度分析的潮滩微相识别敏感指标,并将其应用到该区域的全新世钻孔潮滩沉积物中,识别钻孔潮滩沉积微相,据此建立研究区全新世早期的海平面曲线。研究表明:杭州湾北岸现代高潮滩盐沼沉积物粘土含量明显高于高潮滩下部和中潮滩,而砂含量与之相反;高潮滩盐沼平均粒径等粒度参数明显小于中、高潮滩的粒度参数;盐沼沉积物粒度频率曲线峰态宽缓,明显区别于高潮滩下部和中潮滩。上述现代潮滩微相粒度敏感指标可成功应用到钻孔潮滩沉积微相划分中,并建立了该区域全新世早期海平面曲线。曲线显示,9700~8700 cal a BP期间海平面上升约11.6 m,海平面上升速率可达1.2 cm/a。现代潮滩不同位置沉积物粒度参数的规律性差异可作为潮滩微相识别的有效指标,为古潮滩沉积微相识别和古海平面重建提供参考依据。

岱山—洋山跨海通道水沙环境影响数值模拟研究

杭州湾是世界闻名的强潮河口,具有不规则的岸线边界、独特的地形地貌特征和复杂的水动力泥沙环境。岱山—洋山跨海通道位于杭州湾湾口水域,将岱山与洋山近35km连通,实现了上海—洋山—岱山—舟山—宁波跨海通道的全线贯通,其建设具有非常重要的意义。基于考虑波浪作用的潮流泥沙数值模型,讨论了岱山—洋山跨海通道几种工况对杭州湾大范围海域水沙环境的影响。研究结果表明:跨海通道实施后潮位变化在大桥轴线附近较为敏感,远离则基本没有影响,高低潮位变化幅度大多在2 cm以内。杭州湾涨落潮量减小小于0.6%。水流流态和水下地形仅在大桥附近水域存在明显变化。从对杭州湾水沙环境影响角度考虑,岱山—洋山跨海通道几种工况均可行,建议关注桥墩和人工岛附近的局部冲刷问题。

2022年初5次降雪过程分析和预报着眼点

本文采用ECMWF(European Centre for Medium-Range Weather Forecasts)细网格和NCEP(National Centers for Environmental Prediction)模式数据、NCEP 1°×1°再分析资料、降雪加密观测和常规资料,对2022年初的5次降雪过程进行对比分析,发现5次降雪过程均为雨转雪过程,且持续时间相对较短,平原为雨夹雪或小雪到中雪,山区中到大雪,局部暴雪,数值模式预报的积雪深度与实况相差甚远;大尺度环流形势为500 hPa中低纬南支槽或弱波动配合700 hPa上的暖湿气流和中低层冷空气,造成边界层浅薄的冷垫上温度骤降而在短时间内形成降雪;相较于平原地区,高山区上空温度层结与最大上升运动中心的配置,有利于降雪粒子较长时间维持在有利于枝状雪花的形成区域,且高山区云底云水含量显著偏低、整层温度足够低,故高山区更利于暴雪的形成。

无锡运河文化遗产的保护与利用策略研究

文化遗产具有普遍的历史、艺术和科学价值,以及特殊的经济和思想价值。基于文献分析、实地调研等方法,对大运河无锡段沿线的物质文化遗产赋存情况进行梳理和统计分析,发现文化遗产保护利用中存在以下问题:内容阐释挖掘不够,价值传播指向模糊;遗产存在诸多历史断点,难以展现文化全貌;遗产地理空间分散,难以连片成面开发;以静态静物展示为主,缺乏沉浸式场景开发。基于文化遗产的普遍价值和特殊价值维度,建议加强内容挖掘、关注文化传播的价值导向,加强顶层设计、增强文化遗产时空连续性,构建场景化主题、开发沉浸式体验空间。

论弥尔顿对荷马史诗传统中女性之“他者”定位的改写——以《伊利亚特》和《失乐园》为例

荷马在其被视为“西方最古老的史诗”《伊利亚特》里将女性人物定位为“他者”,由此开启西方史诗对女性的“自我”之探索。在西方史诗史上,随着史诗从“原始史诗”向“文学史诗”发展,史诗里的女性形象慢慢脱离“他者”而向“自我”演进。本文在分析“原始史诗”之代表《伊利亚特》中女性人物的基础上,进一步阐明:弥尔顿在“文学史诗之冠”《失乐园》中改写了荷马史诗传统中女性之“他者”定位。首先,《失乐园》的史诗英雄虽名为亚当夏娃之整体,但很大程度上乃史诗中唯一的女性夏娃之个体,弥尔顿在塑造史诗英雄的过程中将其主要关注锁定在夏娃身上。其次,诗人始终突显夏娃的“自我”,不仅展示了夏娃因“原初自我”中的“自恋”“自傲”而堕落的经过,而且呈现了夏娃通过“自省”“自知”“自赎”而将“自我”重构为“生态自我”并获得精神再生的过程。女性人物在史诗中的重新定位是弥尔顿对史诗传统的重要贡献之一。

基于优化第三代非支配排序遗传算法的城市应急设施模糊选址

以杭州市上城区2022年全年核酸检测点记录数据为基础,采用优化型第三代非支配排序遗传算法(NSGA3),将杭州市上城区划分为10786个50 m×50 m的人口点,模拟每个人口点去往周边核酸检测这一聚集性应急行为,并进行50000次迭代.将迭代结果进行核密度分析,分别得出基于单设施点的15 min生活圈优化结果、基于双设施点的15 min生活圈优化结果、基于适老化需求修正的设施点优化结果,以及基于单设施点的5 min生活圈优化结果.结果显示,以单设施点的15 min生活圈优化结果为例,在不改变服务能力的前提下,基于优化NSGA3迭代后的核酸检测点网络,将设施平均可达时间从292.44 s优化到了264.62 s.基于核酸检测这一行为结果形成城市应急设施的模糊选址范围,得出“小集聚-大分散”空间规律;在此基础上将模糊选址范围转化为“社区级多功能应急空间”,为将来发生应急事件,进行临时应急设施选点决策时提供理论建议.

杭州第十九届亚洲运动会是继北京奥运会后,中国又一次承办的国际综合性体育赛事。杭州成功举办第十九届亚运会,向世界展现了中国文化自信,同时也为杭州建设文化强市带来新思考。那么在亚运会结束后如何保留其所留下的亚运会遗产以及如何合理运用、促进文旅结合、加强文化交流是杭州、浙江、中国需要考虑的重要问题。文章从杭州亚运会彰显中华文化魅力、全力做好后亚运杭州文化遗产保护与开发、推动后亚运杭州文化产业创新发展、加强后亚运杭州文化交流与国际传播四个方面对后亚运杭州建设文化强市进行了探析。

适老化视角下居住型轨道交通站域街道步行适宜性研究

在轨道交通迅速发展、老龄化程度不断提高的当下,老年人使用轨道交通却遇到多种阻碍。轨道站域街道作为老年人使用轨道交通的“最后一公里”,同时也作为城市开发的重点区域,其街道空间品质的提升不容忽视。构建轨道交通站域街道适老化的步行适宜性评价体系,并利用AHP层次分析法分析各指标重要性的差异,选择杭州市9个典型居住型地铁站点,通过城市POI数据及街景数据等,对各站点安全性、舒适度和便捷性及各评价指标进行分析。总体上看,各居住型地铁站域街道的适老化步行适宜性较弱,较多站点在无障碍设施、站点可达性和步行环境等方面存在不足,今后应以“便捷性为主导,安全性为保障,兼顾舒适性”为原则,不断提升轨道交通站域街道步行适宜性,提升城市整体步行环境品质。

重构历史:古尔纳《天堂》中的非洲叙事

阿卜杜勒-拉扎克·古尔纳在《天堂》中将被殖民文学边缘化的非洲人置于中心位置,让欧洲殖民者成为“被凝视”的对象,从非洲人的视角讲述非洲历史,展现殖民主义对非洲(人)的影响,以及一战前东非地区社会、经济与文化的历史变迁。本文从逆写帝国、嵌套结构、旅行叙事和多元文化杂糅四个方面,分析古尔纳重写非洲历史、重塑非洲形象的方式。小说采用嵌套结构,以个体历史为经,以地方史与民族/国家历史为纬,钩沉殖民时期的非洲历史,拓展了文本的历史维度。古尔纳将旅行叙事与成长、身份建构结合在一起,通过空间位移表征身份/认同的“流动性”和“混杂性”,揭示非洲文化多元主义的历史渊源,呈现出一种世界主义与共同体的历史意识。

主观感知下体育公园建成环境对居民运动行为的影响研究

为探究体育公园建成环境对居民运动行为的影响,揭示建成环境、感知反馈与运动行为的内在关系,以杭州城北体育公园为研究对象,将建成环境、环境感知与运动行为三者关联化,通过调研行为数据进行实证研究。结果表明,在影响居民游憩满意度的感知评价中,环境度对运动行为影响最大。继续研究发现,要素感知对不同强度运动的发生频率和持续时间的影响效度不同。在研究结果的基础上提出了改善体育公园运动建成环境品质的建议。

TOD模式下历史街区的复兴——以杭州西湖地区为例

我国大规模城市轨道交通的建设为城市交通发展模式的转型奠定了基础。大容量、高品质的公交系统是大城市集约紧凑和高竞争活力的保证。从国际经验来看,大城市的城市更新、历史街区的振兴发展与交通模式的转型构成当代城市规划和设计中不可分割的重要议题。本文以杭州西湖武林路街区规划设计为例,探讨以公共交通为导向的城市开发策略(TOD)作为历史街区复兴的催化剂对该地区空间发展战略、交通组织、公共空间和景观提升等方面的作用,实现“湖城融合”及人们对历史街区的沉浸式体验,提出历史街区复兴的TOD规划设计策略与建议。
