搜集并整理武汉主城区地震安全性评价控制性钻孔SPT-N资料，配合武汉市地震动参数小区划成果，采用规范法对各场地土层在罕遇地震作用下液化可能性进行判别。以液化指数作为分区指标并结合各场地坐标，绘制武汉主城区液化潜能分区图。分区图初步预测了罕遇地震发生以后，可能发生液化的区域及其严重性，且表明无论是分布面积还是液化潜能，长江右岸均大于长江左岸。通过与4次历史大震液化资料的对比分析，武汉主城区可能液化场地具有地下水位埋深浅、液化土层分布范围广、埋藏深度大的特点。 相似文献

城市边缘区位于城市与乡村之间的过渡交接地带,既是城市扩张的前沿,也是城乡建设和用地置换中最具活力的地区。准确识别城市边缘区的空间范围一直是城市空间结构研究的核心问题,有助于从城乡对比的角度来衡量城市化程度。本文以城市边缘区的空间突变特征为切入点,基于格网尺度评价构建基于多源数据的城市边缘区特征识别指标,然后采用小波变换检测进行特征值突变点群的识别,并利用基于Delaunay的自动边长阈值的边界提取算法识别突变点群内外边界,从而实现了一种基于空间突变特征的城市边缘区提取方法。最后,以江阴市作为研究区进行了实证分析,并将本文方法提取结果与通过信息熵模型和土地利用程度综合指数模型提取城市边缘区的经典方法提取结果进行对比,经典方法所提取的城市边缘区结果更为混乱分散,而本文结果更为完整客观。将本文方法提取结果与使用土地利用数据与行政区划统计年鉴数据构建城市边缘区识别指标进行突变检测的不同指标方法提取结果进行对比,二者重叠度达88.03%,体现了本文方法的正确性,而从局部细节分析来看,本文结果更符合实际情况。为了更好地验证本文方法的有效性,利用景观格局指数对本文方法和不同指标方法提取的城市建成区、城市边缘区和乡村腹地的范围进行检验：从斑块类型层级指数分析, 2种方法划定的区域都具有典型的空间特征;而从景观层级指数分析,本文识别出的边缘区所计算的斑块密度、最大斑块指数、景观分离度、景观破碎化指数和香农多样性指数均高于对比方法,而蔓延度和香农均匀度均低于对比方法,说明本文识别的城市边缘区范围内景观破碎化程度和异质性更高,景观分布不均匀,社会经济条件更复杂,从而证明了本方法的有效性,尤其适合于非闭合环状的城市边缘区的提取。 相似文献

From the ecological viewpoint this paper discusses the urban spatial-temporal relationship.We take regional towns and cities as a complex man-land system of urban eco-community,This complex man-land system comprises two elements of “man“ and “land“,Here,“man“ means organization with self-determined consciousness,and “land“ means the physical environment (niche ) that “man “depends on .The complex man-land system has three basic components,They are individual,population and community,Therefore there are six types of spatial relationship for the complex man-land system.They are individual,population,community,man-man,land-land and man-land spatial realtionships,Taking the Pearl(Zhujiang) River Delta as a case study,the authors found some evidence of the urban spatial relationship from the remote sensing data,Firstly,the concentration and diffusion of the cities spatial relationship was found in the remote sensing imagery,Most of the cities concentrate in the core area of the Pearl River Delta ,but the diffusion situation is also significant ,Secondly,the growth behavior and succession behavior of the urban spatial relationship was found in the remote sensing images comparison with different temporal data ,Thirdly,the inheritance,break ,or meeting emergency behavior was observed from the remoted sensing data.Fourthly,the authors found many cases of symbiosis and competi-tion in the remote sensing data of the Pearl River Delta ,Fifthly,The autoeciousness,stranglehold and invasion behavior of the urban spatial relationship was discovered from the remote sensing data. 相似文献

九江市城市垃圾卫生填埋场场址适宜性评价优选 总被引：1，自引：0，他引：1
利用层次分析法对九江市5个候选垃圾场地进行了适宜性评价优选,通过场地评价影响因子定权重和采用多目标线性加权函数数学模型计算各候选场址的综合评价得分,结果依次为场地5>场地1>场地2>场地3>场地4。可见场地5为5个候选场地中最佳适宜性垃圾填埋场场址,在很大程度上减少了选址过程中人为主观因素影响和定性分析过多的缺点,为九江市重建垃圾填埋场地选址提供了客观依据。 相似文献

同城化背景下城市建设用地的时空变化,对于城市制定科学规划、促进地区可持续发展具有重要意义。本文以遥感影像为主要数据源,提取3个时期太原市城区和榆次城区建设用地信息,分析了研究区建设用地扩张的区域以及时空动态变化特征;利用相关的统计数据,采用灰色关联度模型,探究研究区建设用地扩张的主要驱动因素。结果表明:研究区的建设用地面积不断扩张。研究区太原部分的建设用地重心先向西北再向东南迁移,研究区榆次部分的建设用地重心整体向西北方向迁移。研究区建设用地扩张主要受城镇化水平、经济发展水平、产业结构、政策因素和交通因素等5个因素影响,但各个因素对建设用地扩张的推动力大小不同。 相似文献

基于政府大数据的北京城市空间发展模式分析 总被引：1，自引：0，他引：1
城市的发展都有各自的特征。这些特征通常是受城市发展过程中政府决策及规划政策的影响而形成。作为我国首都,同时也是人口最稠密的城市,北京市的城市建设用地在过去20年快速城镇化进程中持续扩张。笔者认为,北京市城市扩张期间,城市建设用地开发模式有特定的规律和空间特征。本文中,笔者采用非负矩阵分解(NMF)的方法,对北京市建设用地规划许可发放数据进行挖掘,以此识别城市空间发展模式。笔者发现这个阶段包含了两种主要发展模式,同时也结合诸多辅助信息对这两种模式进行了深入的分析和解释。本文中使用的城市空间发展模式识别方法可以推广到其他区域的城市研究中,对城市设计及政府决策工作起到较大作用。 相似文献

针对城市建成区提取过程中,仅依赖单一数据源导致精度不够的问题,本文基于面向对象分类方法和利用土地类型信息标准差统计变量,实现遥感影像中城市建城区边界的提取,并以该建成区为依据对河南省虞城县的城区空间扩张特征作了分析。实验中首先采用均值漂移分割算法对高分一号遥感影像实现分割,然后利用决策树分类算法实现土地利用类型分类,最后基于0.1 km × 0.1 km窗口统计土地利用类型标准差信息,获取建成区边界。面向实际应用,以河南省虞城县为例,采用高分一号影像获得虞城县2017年建成区数据,并基于该数据采用多个TM影像提取城区其他年份的建成区边界,实现河南省虞城县城区空间扩张特征分析。结果表明,本文方法获取的建成区边界精度较一般的监督分类提取边界有进一步的提高,精度达到89%。进而说明结合高分辨率影像提取多个年份的建成区数据的可靠性,在城市扩张研究中,对仅利用低空间分辨率提取精度不够问题和仅利用高分辨影像提取效率低等问题提供了较好的解决方案。 相似文献

The protection of historic sites, especially their relationship with urban development, has become a worldwide issue, both in developed and developing countries. In the context of rapid urbanization in China, the realistic compatibility between urban construction and the protection of historic sites is always a key research topic. In this study, first, to comprehend their spatial distribution patterns, 828 historic sites throughout the country are selected based on certain criteria. Then, we conduct quantitative research using GIS software, adopting indicators that include Nearest Neighbor Index, Gini Coefficient, and Geographic Concentration Index to analyze the spatial characteristics of historic sites on the three levels of city, province and nation. The results indicate that the spatial distribution of the different types of historic sites is an agglomeration on the nationwide scale, most of which is located in the regions of the Pearl (Zhujiang) River Delta, Yangtze (Changjiang) River Delta and Beijing-Tianjin Region. Because the majority of historic sites are located within approximately 10 km of the downtown area, a certain pattern has emerged, showing that the larger cities own more historic areas, which are in a more incomplete state of preservation, indicating the fragmentation of heritage spaces. The formation mechanism of the historic sites’ distribution pattern is based on the conditions of the cities/towns as well as the bid-rent theory. 相似文献
