基于ESDA-GIS的新疆能源碳排放空间差异动态演化分析   总被引:1,自引:1,他引:0  
基于2002-2014年新疆能源碳排放数据,采用Arc GIS9.3,运用标准差椭圆与ESDA相结合的方法深入剖析了新疆能源碳排放空间差异动态演变特征,结果表明:新疆各地、州、市能源碳排放具有显著的空间自相关性;热点和次热点区主要集中分布在北疆地区,且呈现不断缩小的趋势,而次冷点和冷点区域范围则不断扩大;能源碳排放呈现出东北—西南、西北—东南的空间分布格局,标准差椭圆呈现出逐渐向南疆地区移动的趋势,以昌吉地区为核心,范围包括了新疆能源碳排放主体地区,能源碳排放重心呈现东南—东北—东北方向的变动趋势;最后,基于得出的结论提出相应的解决对策,旨在为实现新疆经济、能源、环境的协调发展建言献策。  相似文献

结合江苏省经济结构和自然环境情况,选择合适的碳排放模型进行核算,得到江苏省各区县的碳排放量,综合DMSP/OLS夜间灯光影像和NDVI数据,再结合人口、GDP和工业生产总值数据,构建碳排放的空间滞后回归模型并开展江苏省碳排放的空间分布模拟,得到大小为1km×1km的碳排放空间格网,并对模拟结果纠正,用以研究江苏省各区县的碳排放量分布情况。结果表明,江苏省碳排放清晰地呈现出"苏南苏北苏中"的格局,苏南地区分布着以苏州、无锡为中心和以南京市区为中心的碳排放高值集聚的"热点"区域;在各区县内部,碳排放的空间分布与人口、GDP产值等密切相关,明显集中于人口、工业聚集的市区和县城区域。  相似文献

以能源产区陕西省榆林市的12个区县为研究单元,在Geo Da和Arc GIS等软件的支持下,结合趋势分析和空间统计方法,分析2005—2010年榆林县域尺度下的能源消费碳排放强度的空间格局特征与空间分异机制。榆林各区县能源消费碳排放强度水平差异明显,总体差异呈扩大趋势,两极分化加剧。县域碳排放强度南北走向上表现出逐渐减小趋势,东西走向上具有微弱的"U"型变化态势。总体上,东北部区县碳排放强度高于西南部。各区县碳排放强度具有正的空间关联分布特征,且处于低水平非均衡空间分布状态,空间依赖性明显。结合相关性分析,榆林区县碳排放强度具有极化区、扩散区、塌陷区和传染区4个特征。"热点"主要分布在东北部三县,"冷点"主要分布于南部六县。能源资源分布不均、经济总量以及产业结构差异是造成榆林碳排放强度空间分布不均的主要原因。  相似文献

基于空间杜宾模型的中国高学历人才时空分异研究   总被引:1,自引:0,他引:1  
基于2001~2016年全国统计年鉴数据,采用集聚度分析和空间自相关分析等方法,描绘中国高学历人才的空间格局及变化,并采用空间杜宾模型,探究影响高学历人才空间分布的主要因素及空间溢出效应。结果表明:(1)中国人才分布表现出较大的非均衡性,集聚程度表现为东南高、西北低,且2000~2015年间,人才稀疏区面积下降而集聚区面积上升;(2)中国人才密度的全局莫兰指数为正,表明中国的高学历人才分布具有一定的空间集聚特征,而2000~2015年此指数有所下降,表明人才分布整体上有分散趋势。2000年热点区与次级热点区主要分布于京津冀和长三角地区,其中热点区为京、津、沪;而2015年,热点以及冷点区域均有所扩张,表明局部地区人才仍然有集中化的趋势;(3)工资水平、高校发展、公共服务水平是决定人才空间分布的主要因素,但没有证据表明生活支出比、失业率、房价有显著影响。人才分布具有明显的空间溢出效应,同时工资水平、高校发展、公共服务水平等影响因素也具有明显的空间溢出效应。  相似文献

精确刻画放牧强度时空格局是深刻理解青藏地区高寒草地服务功能动态及其驱动机制的重要基础,对辅助制定区域生态安全和可持续发展战略具有意义。基于牲畜年末存栏量、牧区人口密度、生长季NDVI、年降水量、年平均气温和居民点分布等数据,采用地理加权随机森林模型,模拟了2000年、2010年和2020年3期青藏地区放牧强度的空间格局,并定量评价了环境因子对放牧强度空间分布解释性的区域差异。结果表明:(1)地理加权随机森林模拟结果可精细地刻画青藏地区放牧强度的空间特征,与经典随机森林模型相比,判定系数更高,平均绝对值误差和均方根误差更低。(2)青藏地区放牧强度呈现东南高、西北低的基本特征,其中,西北部地区放牧强度低于25羊单位/km2的区域约占青藏地区面积的1/2。(3)与2000年和2010年相比,2020年青藏地区放牧强度呈现总体下降、局部抬升的态势;其中,较2010年,2020年放牧强度下降超过1羊单位/km2的区域占牧区面积的61.69%。(4)牧区人口密度是解释放牧强度空间异质性最主要的因素,其相对重要性呈现西高东低的特征,而降水量和生长季NDVI...  相似文献

基于POI数据的山西省旅游景区分类及空间分布特征   总被引:1,自引:1,他引:0  
郭艳萍  刘敏 《地理科学》2021,41(7):1246-1255
运用大数据与传统地理信息系统相结合的方式,以山西旅游景区POI(Point of Interest)数据为研究对象,对其进行分类后,研究其总体空间分布格局、分布方向以及具体地市空间分布特征。结果表明:山西旅游景区总体分布格局呈现晋中地区集聚特征,具体各类旅游景区的集聚形态与程度有所差异。其中,地文景观类旅游景区集聚于晋中、晋东南和晋北东部地区;水域风光类旅游景区以晋中、晋南和晋北东部地区为轴呈条带状分布;生物景观类旅游景区在空间上呈“菱形”状集聚形态;遗址遗迹类旅游景区集聚于晋北和晋东南地区;建筑与设施类旅游景区呈“三角形”状集聚特征;娱乐购物类旅游景区在全省范围内分布较为均匀。旅游景区空间分布方向与山西省区域形状吻合,除娱乐购物类旅游景区分布方向性和向心性不明显之外,其他类别旅游景区均有不同程度的集聚特征;各地市旅游景区分布情况中,水域风光类旅游景区在各市域间分布较为均匀,地文景观类和建筑设施类旅游景区热点区域出现在阳泉市,冷点区域出现在晋城市,但其集聚程度均较低;生物景观类旅游景区热点区域位于长治市,冷点区域位于临汾市和运城市,其集聚程度较高。最后,从自然地理和人文社会两方面对旅游景区空间分布的影响因素进行了定性分析。  相似文献

基于2020年1月24日至12月18日我国314个城市的COVID-19现存确诊数、累计确诊数等统计数据,采用地理数据探索、新兴时空热点分析、空间马尔科夫链、动态面板数据空间杜宾模型等方法分析了COVID-19疫情的时空变化特征。研究发现:我国COVID-19疫情大致划分为大规模快速爆发期、全国严格防控期、全国抑制期、局部复发期、常态化防疫期5个阶段,绝大部分城市的疫情变化特征与全国总体情况类似;新兴时空热点方法识别出4种类型共124个疫情冷热点,其中增强热点24个、振荡热点27个、持续冷点16个、渐少的冷点57个;疫情热点主要分布于中东部地区特别是湖北周边区域,疫情冷点主要分布于西南、西北及东北地区;各城市现存确诊人数的马尔科夫链转移概率矩阵分析结果显示,各种类型维持现状的概率大于0. 893,向下转移的平均概率明显高于向上转移的概率,在不同空间滞后类型的影响下各类型转移概率发生明显变化;动态面板空间杜宾模型估计结果显示314个城市现存确诊数具有显著的时空自相关性且不同阶段有明显差异。  相似文献

基于空间视角,结合中国284个地级及以上城市2011—2019年的面板数据,实证检验了数字经济对旅游发展影响的空间效应及作用机理。结果表明:1)研究期内,数字经济与旅游发展均呈现显著的空间正相关。其中,数字经济的热点区被“空间锁定”于东南沿海地区,而位于中西部的冷点区则大幅收缩;旅游发展的热点区主要分布在长三角城市群和滇桂黔渝,冷点区位于山东半岛中西部并逐步向南延伸。2)中国情境下,数字经济既能助力本地旅游发展,同时存在显著的正向空间溢出效应。从区域异质性看,直接效应虽在各地均显著为正,但在东部地区的作用强度明显大于中西部及东北地区;空间溢出效应在东部得到完全彰显,在中部和东北地区表现为部分显著,西部地区则存在“数字隔离”现象。3)数字经济对旅游发展的正向外溢在300 km处达到最优,此后呈地理距离衰减态势,在800 km处到达有效外溢临界点,1 500 km处达到最大衰减边界。4)数字经济各维度中,数字基础设施、数字产业发展和数字普惠金融均能显著驱动本地旅游发展,但仅数字普惠金融的正向溢出有效突破了行政边界,其余二者均表现出不显著的空间溢出效应。  相似文献

运用传统统计分析与ESDA、OLS、GWR等模型分析方法,基于2000-2013年甘肃省县域经济数据对其产业结构差异及变动进行了时空比较分析。结果表明:时间分异方面,甘肃省县域产业结构的绝对和相对差异均呈现缓慢下降趋势;空间分异全局方面,甘肃省县域产业结构水平呈现西高东低、北高南低的趋势,各县产业结构差异性及集聚性显著增强;空间分异局部方面,热点区域分布由2000年的酒泉、兰州向甘肃的西北及东北部扩展,到2013年形成酒嘉地区、兰州和庆阳三个核心的热点地区,基本呈现出自西北向东南的"热点-次热点-冷点-次冷点"带状分布格局。此外,通过OLS、GWR两种模型对比分析,发现后者更能深刻揭示产业结构与各空间因子之间的相互关系,并进一步采用GWR模型对甘肃省产业结构演变的影响因素予以分析。最后,通过相关结论的分析与思考,以期为甘肃省产业结构优化升级提供重要的决策依据。  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
