南京市旅游景区景点系统空间结构分形研究   总被引:19,自引:2,他引:17  
应用分形理论,以南京市旅游景区景点系统为例,测算出其聚集维数、网格信息维数和空间关联维数三种分形维数,对景区景点系统的空间结构进行研究。通过对维数值和分维数坐标图进行了分析,认为南京市景区景点体系的空间结构是分形的,系统的有序度高,空间结构紧致,具有景点体系空间结构演化自组织优化的趋势,南京市景区景点的空间分布集聚性很强,且是沿着某些方向上的集聚,自组织优化趋势受到无序因素的干扰而打断,空间结构需要进行调整。  相似文献

绿带是阻止城市蔓延、提高城市生态安全格局的重要手段,其游憩开发能够为大都市游憩空间紧缺提供有效的解决途径。以北京市第二道绿带为研究区,以2013年绿带内6种类型游憩空间(共448处)为研究对象,运用Kernel核密度算法等空间分析方法,从北京市绿带游憩空间的整体分布格局、规模容量特征和各类型游憩空间分布特征及成因三个层面进行分析。主要结论:① 从整体分布格局来看,北京市绿带内形成了若干游憩空间集聚区域,游憩空间结构出现“北密南疏”的整体特征;北部游憩空间集聚程度高且分布连续成带,南部游憩空间集聚程度较低且分布离散成团;北部温榆河沿岸地区游憩空间大量集聚,成为绿带游憩空间结构的主要骨架。② 从规模容量特征来看,占地规模较大的游憩空间呈集聚分布,规模较小的游憩空间呈分散分布,绿带内已形成了6个由面积规模较大的游憩空间密集分布构成的热点区。③ 绿带内6种类型游憩空间分布特征及成因表现为:绿带内的资源环境本底决定了既有吸引物游憩空间的空间特征;政策性规划引导郊野休闲公园空间分布相对均匀;重要水系与运动健身游憩空间的空间分布高度关联;主题活动游憩空间更倾向于靠近主要交通干道;会议度假游憩空间与北京市地热资源分布契合度高;民俗体验游憩空间大量分布在海淀区上庄水库周边。揭示了北京市绿带游憩空间布局情况,为中国绿带游憩体系的统筹建设、空间结构调整和布局优化提供了参考。  相似文献

针对不同维数的特殊地理意义挖掘不足、分维测算方法的合理改进缺乏、分形方法与其他方法的互补融合不够等既有研究存在的问题,综合运用三种基本分维和拓扑图论、社会网络分析、GIS方法,以安康市为例,刻画山地城市旅游景区空间结构的分形特征。结果表明:(1)统筹考虑地理中心性和网络中心性选定的中心景区吸引作用强,但吸附半径有限,景区空间结构因而表现出多分形特征,子系统的分形特征与市域地貌格局有关;(2)安康市景区系统分形结构较复杂,其自组织演化是以中心城区等局部集聚中心为节点,沿汉江干支流及主要交通干道等线状要素展开的过程;(3)受山地地形地质条件及其形塑的道路特点影响,安康市景区间的通达性和关联性总体较好,但旅游交通网络的回路性较差;(4)安康市景区分布的空间集聚和轴线依托特征突出、多中心结构形态初显,景区系统演化的有序性较强且有自组织优化趋势,总体上有利于景区合理布局的形成。研究可为旅游空间结构研究、山地城市分形研究提供参考。  相似文献

中国少数民族特色村寨空间结构识别及影响机理研究   总被引:2,自引:0,他引:2  
陈国磊  罗静  曾菊新  田野  董莹 《地理科学》2018,38(9):1422-1429
以全国1 057个少数民族特色村寨为对象,探究民族村寨空间结构及相关影响机理。研究表明: 民族村寨空间分布上呈凝聚型分布,且空间分异较为明显;核密度格局以湘黔桂交界为单核集聚中心的等级分布特征,呈“山”字形坐落态势; 民族村寨系统分形特征显著,自组织演化中围绕武夷山、峨眉山、长白山等不同山脉地带展开,分形结构复杂;民族村寨正空间相关,冷热点区呈东西两极分化现象;地形起伏及地貌多样的中高海拔山地、主要水系及河流上游等是民族村寨内生发展基础;距离中心城市较远、高素质高技能专业人才、民族文化及民族分布等促进了民族村寨的留存和发展。  相似文献

运用分形模型,分析了江苏省城市体系的规模结构和空间结构。首位度指数表明,江苏城市体系规模分布已开始从首位型向序列型转变。Hausdorff分形维数表明,规模结构仍相对松散,首位城市仍具一定垄断性但已不是绝对垄断地位。空间关联维数表明,江苏城市体系具有明显的交通轴线分布特征。牛鸦维数比显示,江苏城市体系的交通网络通达性优良,各城市间联系较为紧密。集聚维数显示,江苏全省、南部区域、北部区域城市体系空间分布都呈集聚态;但南部区域已表现出一定程度的均匀分布格局,而北部区域的空间分布集聚程度却较高。在上述基础上,对江苏城市体系结构的优化提出了建议。  相似文献

尚正永  白永平 《山地学报》2007,25(2):142-147
运用分形理论,对赣州市城镇体系的规模分布和空间结构的分形特征进行了实证分析,得到以下结论:(1)在城镇规模分布方面,中等位序的城市较多,人口分布比较均衡,认为是一种较低水平的均衡;(2)在城镇空间结构方面,城镇空间分布呈现出集聚性特征,城镇的空间关联程度不够紧密,空间相互作用强度不大。在上述结论的基础上对赣州市城镇体系建设提出了建议。  相似文献

国家森林公园空间分布格局及其影响因素研究   总被引:1,自引:0,他引:1  
国家森林公园是我国生态文明建设的重要载体之一。以1994、2004年和2019年国家森林公园为研究对象,综合运用空间分析技术系统探究其空间分布格局及成因,旨在为国家森林公园空间布局优化和健康可持续发展提供科学参考。结果表明:(1)国家森林公园主要分布在胡焕庸线以东,大致形成了以京津冀、长三角、川渝交界和湘赣交界地区为核心的高密度分布地区,呈现出“大集聚、小分散”的分布格局。(2)国家森林公园系统分形特征明显,分形结构较为复杂。(3)国家森林公园省际间分布差异明显,三大地带间呈现东西少、中部多的“凸字形”分异规律,八大分区间呈现“由长江中下游、西南地区向东北和黄河中游地区递减”。(4)国家森林公园热点区呈现出一定的不稳定性,其中黑龙江、江苏和浙江发展较为活跃,持续保持在热点区域,而新疆、西藏和四川等地基本上都处于冷点区域,森林公园发展较为缓慢。(5)地形、降水量、客源市场和旅游资源禀赋是影响国家森林公园空间分布格局的主要因素。  相似文献

基于分形维数的湖州旅游景区系统空间结构优化研究   总被引:4,自引:1,他引:3  
崔大树  孙杨 《地理科学》2011,31(3):337-343
中小城市旅游业空间结构的优化及其与更大空间范围的旅游资源进行整合、衔接,是目前非中心旅游地区旅游资源开发和旅游业空间结构优化的难点。运用分形理论对湖州市旅游景区系统空间结构优化进行研究,聚集维数的测算显示湖州景区系统的空间分布聚集性较强,关联维数的测算结果显示其具有多分形特征。据此,湖州市旅游景区系统空间结构的优化主要为两个方面,即完善"两核心三组团"的旅游空间结构;加强"点—轴—面"交通体系建设,促进湖州接轨长三角地区旅游系统。  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献
