2021年第6号(2106)台风“烟花”是我国有监测记录以来对大陆影响时间最长的台风,为华东地区带来了暴雨级的降水。基于台风“烟花”(2106)影响江苏南通地区期间小时尺度高分辨率的降水稳定同位素数据,分析了降水稳定同位素组成变化特征及影响因素。结果表明:降水δ18O值为-11.7‰~-2.3‰,加权平均值为-7.4‰。台风影响前期,采样点水汽主要来源于附近海域,受云下蒸发效应的影响,降水δ18O值相对偏正;台风影响中期,受相对湿度与上游累积对流强度的共同控制,降水δ18O值逐渐偏负。但相较于已发表的我国台风降水δ18O极端偏负值(-20.1‰~-12.6‰),台风“烟花”(2106)降水δ18O极值并未显著偏负,主要是由于上游累积对流降水历时较短以及台风登陆后水汽缺乏大规模有组织性的对流活动。  相似文献

为研究台风时期对流层延迟的演变,基于ERA5再分析数据,计算西北太平洋1822号台风“山竹”、1622号台风“海马”以及西北大西洋1709号飓风(台风)“厄玛”时期各高度层可降水量及对应的对流层延迟。结果表明,计算得到的对流层延迟与IGS对流层延迟产品存在明显时空差异,台风对测站影响越强,两者一致性越差。进一步分析表明,台风过境会引起可降水量及各高度层水汽分布比例发生变化,两者均会影响对流层延迟,其中,可降水量的变化占主导。在可降水量一定、850~500 hPa高度层中水汽含量占比最大时,对流层延迟最大。台风使分布于对流层低层的水汽增多,使用传统对流层延迟模型估算对流层延迟,可能会产生额外误差。  相似文献

利用NCEP1°×1°的再分析资料,用大尺度水汽通量流函数和速度势以及水汽收支对台风“麦莎”在移动过程中水汽输送流函数和速度势进行了分析。结果表明:台风“麦沙”在北上过程中,主要有2支水汽通道,一支是从太平洋开始向西经赤道到达印度洋,在索马里转向,经过孟家加拉湾呈西南气流向西北方向输送;另一支来自副高南侧偏东气流。计算分析还表明,用无辐散风流场来定台风中心要比用总的流场更精确。  相似文献

自1970年4月22日美国首次举行“地球日”以来,该活动得到全世界人民的认可,从此“地球日”也成为“世界地球日”,它唤起人类爱护地球、保护家园的意识,促进资源开发与环境保护的协调发展。我国也于20世纪90年代起加入了这项活动,每年的4月22日,国土资源部都要在全国开展“世界地球日”宣传活动,[第一段]  相似文献

针对近年来大气能见度严重恶化的问题,利用成都市气象局提供的1980~2010年13个站点的观测资料,分别采用累积百分率法、Ridit分析法和“非常好”能见度出现的频率法对该地区具有代表性的5个县(金堂、大邑、新津、彭州和温江)的能见度的变化趋势进行了详细分析.结果表明,三种研究方法的分析结果较为一致.从年代际对比的角度而言,金堂、大邑、新津20世纪80年代和90年代能见度高,21世纪初能见度低,彭州反之;温江20世纪80年代变化不显著,90年代略高于总体平均能见度,21世纪又降低.从年变化趋势的角度而言,除彭州外,金堂、大邑和新津的能见度均呈下降趋势,且季节差异也在逐渐缩小.从季节变化特征的角度而言,5个站点的能见度均表现出夏季最高,春季和秋季次之,冬季最低.夏季“非常好”能见度出现的频率表明,相比彭州而言,其它4个站点的能见度较差,受污染情况较严重.  相似文献

The growing attention on urban tourism was very widespread. There are two angles to study urban tourism: supply-side and demand-side. And the supply-side of the tourism remains very important. The RBD (Recreation Business District) is a useful framework to understand the components of urban tourism and how they fit together. The paper begins with a review on the RBD and the spatial structure of tourism in urban areas and then attempts to develop a more general understanding of the spatial structure evolution of RBDs in a tourist-historic city—Suzhou. The spatial structures and functions of the RBDs in Suzhou are examined, based on field observations, interviews with city officials and industry leaders, and a review of available documents. The urban tourism of Suzhou has developed in a range of contexts, that various types of RBDs have emerged as a result of different urban development strategies. The spatial structure has evolved from the past “Single-cored Structure“ to “Double-cored Structure“ at present, and then to “Chain Structure“ in the future. The spatial form and evolution of RBD in Suzhou are closely relative with its urban spatial expansion. Urban area dispersal is the prerequisite of the emergence of the RBD. Planning and constructing the RBD becomes a new impetus to urban growth or renewal. Finally, a number of strategies for planning and developing the RBD in Suzhou are suggested. The different RBDs should adopt different strategies.Intensification can be the possible strategy for the RBDs in the ancient city. Accreting with the urban theme park or engrafting on the Jinji Lake is suggested respectively for the RBD in the Suzhou New District and the Suzhou Indus-trial Park.  相似文献

Comparison of various definitions or discusses of ur-ban competitiveness (UC) reveals that these arguments from different scholars usually start from the following aspects: 1) the capacity of attracting, capturing, pos-sessing, controlling and transforming resources; 2) the life quality level; 3) the capacity of value or wealth creation; 4) the capacity of urban sustainable develop-ment. Actually, among these four aspects there exists a delicate logistic relation. The perspectives of urban sus…  相似文献

There are many defects in researches on the relationship of the regional financial development(FD)and economic growth of China,such as simply assuming the causality direction,not highlighting financial institution,us-ing incomplete financial indicator,etc.This article,taking Suzhou City of Jiangsu Province,China as a case,builds a simple model to study the level of FD from three aspects of financial scale,structure and institution.Three original in-dicators of PRIVY(private investment/aggregate investment),DEPTH(aggregate loan/GDP)and FDIVG(FDI/GDP)are used to construct the FD economic indicator through Principal Component Analysis approach.Then we use Granger method to analyze the relationship between the FD and the economic growth of Suzhou.Empirical test results show that the FD of Suzhou is the Granger reason of economic growth,while economic growth is not the reason for FD,because the relationship between the FD and the economic growth of Suzhou is just in the"supply-leading"period.In terms of Suzhou experiences,the local government should strengthen the protection of private investment,improve the institutional environment,and establish the reasonable financial structure.So we can concluded that FD could play a great role in promoting economic growth at the economy takeoff stage.  相似文献

The urban competitive advantages rely on the combination and interaction of influential factors. As a dynamic progressive process, the city at different time has different competition influential factors combination. Because of this, the urban competitive advantages take on time-series characteristics. Stages of urban competition can be summed up into three ones, the basic factor-driven, the investment-driven and the innovation-driven. The finding of the study on the stages of urban competitive advantages in Suzhou is that in the current stage of Suzhou its competitive advantage is the investment-driven. The investment, especially FDI, plays remarkable functions for Suzhou competition with other cities.  相似文献

Helicopters are often used in mountain rescue both for rescuers moving in the area of accidents and for evacuating victims, but in steep or forested terrain finding a landing place can be problematic. The main aim of this research is to use Digital Elevation Model(DEM) and cartographic database analysis to select locations that can be used as landing site for the rescue helicopters. Methods were based on GIS analysis; both raster and vector data were used for identifying touchdown points for rescue helicopters. Based on DEM data, locations with a low slope gradient were identified; topographic vector data were used for identifying unforested sites. Then buffer zones for buildings and power lines were excluded, and it was checked whether the areas had any topographic features that prevented helicopter landings. The findings were verified on an orthophotomap. In result, GIS analyses have selected 1232 polygons that fulfilled initial criteria. Their verification on orthophotomap has shown that only 55% of them could be potentially used as landing site. Landing sites can be found mainly on side ridges of mountain ranges and in valley beds, when those on ridges are most important in this research. The greatest difficulties and methodological challenges are posed by: identification of sites having a shape which prevents landing, the obsolescence of data due to environment dynamics, the presence of features that are not shown on maps but prevent helicopter landings. A map of landing sites is a very useful tool to conduct rescue operations, but each use of a given landing site requires both in-field and numerical verification. The analysis demonstrated that GIS toolsare useful in pre-planning of rescue missions, and also showed that such data must be kept up-to-date and in-field verification is needed continuously, the more so as it plays an important role in ensuring the safety of rescuers and victims.  相似文献

Based on dynamic theory of system, agriculture is a complex system composed by element, structure, function and development. Firstly, this paper analyzes their connotation and relationship, which could be simply described that in virtue of element integrating and structure optimizing, agricultural system may achieve multifunctionality to meet increasingly diverse demands. As a case study of Suzhou, it concludes that Suzhou has a LP-dependence on agricultural element, and the growth extent of agricultural productivity correlates to the ratio of agricultural labor reducing rate to farmland reducing rate. Agricultural structure of Suzhou changed with time, and in the early 1980s and 2000s it was most notable. Correspondingly, agricultural function has experienced a succession process: ‘production’, ‘production-living’, and ‘production-living-ecology’. At last, based on questionnaires and interviews, some new characteristics and problems of agricultural development in coastal developed region of China have been put forward. Meanwhile, some typical patterns of modern agriculture in Suzhou which adapt to system evolving are also brought up such as export-oriented agriculture, enterprises-leading agriculture, agricultural science and technology parks, characteristic and stereoscopic agriculture, tourism and sightseeing agriculture.
