边境省区县域城镇化与人口迁移的时空演变及机制分析——以广西为例

基于中国第四、五、六次人口普查数据和经济计量方法,以县域为尺度对边境省份广西的城镇化和人口迁移时空演变和动因机制进行分析,结果表明:1)在县域人口城镇化水平提高且与全国均值差距缩小的同时,边境省份大部分地区城镇化率仍低于全国平均水平;从空间上看,县域城镇化呈非均衡发展趋势,中心市辖区水平高、具有一定的辐射作用但分布零散。开放较早的北部湾地区和毗邻发达省份广东的桂东、桂东南城镇化水平高于桂西、桂北地区。2)县域人口迁移具有显著的空间正相关效应,且2000―2010年其空间自相关程度集聚增强,但格局基本保持稳定,县域尺度人口迁移的高值区与城镇化发展较快地区基本同步,集中于桂东南及北部湾地区。3)对于兼有国界、海岸和省界等三类影响人口迁移的边界的广西而言,后两类边界较明显地"吸引"人口向其邻近地区活跃迁移与城镇化集聚,而国界目前对人口流动仍有一定的阻碍作用。4)从影响人口流入地选择的角度看迁移的空间格局与动因,服务业的发展正成为吸纳人口迁入的主要力量,自由贸易、商贸服务、沿边通道与口岸建设以及"一带一路"倡议是当今重塑中国西南边境地理的主要动力。     

县域交通优势度与经济潜能测度及空间格局演变研究

县域交通优势度与经济潜能之间具有密切的联系,客观评价甘肃省县域交通优势度与经济潜能,有利于促进二者协调发展。在借鉴已有研究成果的基础上,通过构建县域交通优势度与经济潜能综合评价指标体系,对2005—2012年甘肃省87个县域进行评价,并采用地理加权回归模型探讨二者之间的空间相关关系。结果显示:1受地形的影响,甘肃县域交通优势度呈现出"核心—外围"模式,核心区以兰州为主向外围逐渐递减。2县域交通优势度差异显著,其中陇中地区的交通优势度最高,并且交通优势度受交通线路的影响较大。3县域经济潜能空间上也呈现出明显的"核心—外围"模式,研究期间,各县域经济潜能值有很大的提高,但"核心—边缘"模式总体格局没有发生变化。4地理加权回归模型显示交通优势度与经济潜能呈正相关关系,回归系数空间上呈现出由中部向西北、东南2个方向递减。据此提出各地区应充分利用交通优势,规避区域交通劣势,促进区域经济发展。     

山区县人口分布的时空特征及主要影响因素分析——以河南省嵩县为例

城镇化过程中山区人口分布的时空特征及其变化规律对协调人地关系和实施乡村振兴具有十分重要的意义。论文基于河南省洛阳市3次农业普查数据,选取嵩县318个村域单元为研究对象,综合运用GIS空间分析和回归方法,分析该县域人口分布的时空演变特征及其影响因素。结果表明：① 嵩县人口分布在空间上极不均衡,高密度区集聚于交通干线附近和地势较为平坦的地区,并随时间推移由点状集聚分布向片状和条带状集聚分布转变;② 人口增长总体上以洛栾高速为界,西北人口增长速度快、东南人口增长速度慢,其中高速增长区主要集中于县城及洛栾高速西北部少数乡镇所在地;③ 人口增长中心位于县城和陆浑水库周围的乡镇所在地,南部深山区乡镇有望形成新的人口集聚地;④ 县域人口分布格局是自然地理条件、地理区位和公共服务设施共同作用的结果。其中,县城可达性对人口分布影响最大,地形起伏度次之,耕地面积和中学可达性较小,但不同因素的影响具有时空异质性。上述结论意味着,山区县可在充分考虑自然条件和资源禀赋差异的基础上,利用城镇化布局、基础设施建设和公共服务设施调整来促进县域人口分布格局的优化。     

江苏省县域综合实力评价及区域分异特征

以县级区域为研究单元，采用因子分析方法和GIS技术，对江苏各县域综合实力进行综合评价，结果表明：1)江苏沿江地区和徐连经济带的综合实力高于中部地区，呈现出分别由南、由北向中部递减的“凹”字型空间格局；2)城市市区的综合实力高于周围农村地区，呈现出由市区向农村逐步递减的“凸”字型空间格局；3)江苏沿江地区的综合实力随着各县、市距上海距离的变化及通达性的难易，呈现出由沿海向内陆的圈层递减特征；4)经济水平、人口生活质量、社会结构水平的区域分异呈现出明显的空间不一致性，三者之间的协调性也表现为显著的由东南向西北逐步递减的特征。     

东北振兴以来吉林省四化发展的协调性研究

运用耦合协调度模型、探索性空间数据分析和障碍度模型,判别东北振兴以来吉林省四化发展的协调性。结果表明：吉林省四化发展水平具有时间波动性和空间非均衡性,仅有农业现代化水平呈现递减态势,工业化和城镇化的空间分异不断缩小,信息化和农业现代化的空间分异逐渐增大;四化发展处于低水平耦合阶段,非同步性特征明显,中部城市群和东部沿边地区耦合度较高,西部内陆地区耦合度低,包括严重失调、中度失调和轻度失调三种类型;四化协调水平相似地区由离散分布向弱集聚状态转变,中部长吉、东部延边和通化地区是四化协调的热点或次热点,热点区县域不断减少,冷点区县域逐渐增加;2003年四化协调的前5项障碍指标是三产产值比重>人均GDP>非农人口比重>万人医院和卫生机构床位数>邮电业务指数,2012年前5项障碍指标是二产产值比重>二产从业人员比重>人均工业总产值>农业地均经济产出>农业劳均农产品产量,子系统障碍度大小排序为城镇化>农业现代化>工业化>信息化。最后,从区域战略政策、经济产业基础和自然地理环境探讨四化协调演化的驱动机制,并提出相应政策建议。     

安徽省县域“人口—经济—空间—环境”城镇化耦合协调性分析

基于新型城镇化背景下县域"人口-经济-空间-环境"城镇化内涵,通过构建县域城镇化协调发展评价指标体系,同时利用熵值法、耦合度及耦合协调度模型,对安徽省61个县域单元2000-2013年4个时间断面县域城镇化人口、经济、空间、环境4个子系统的耦合协调时空格局进行了研究。结果表明:总体上,安徽省县域城镇化耦合度处于低水平阶段,耦合协调度处于由中度失调向轻度失调过渡阶段;空间格局上,省域东部县域耦合协调度高于中部县域,中部县域耦合协调度高于南部和北部县域;在安徽规划五大片区中,皖北片区县域表现为人口城镇化滞后,其他片区县域表现为空间和环境城镇化滞后。该研究成果可为安徽省城镇化发展决策提供科学依据和参考。     

新疆县域城镇化的综合测度及空间分异格局分析

对新疆县域城镇化发展水平进行综合测度及空间分异格局进行分析,能够更好地促进新疆县域城镇化的发展,从而更好地带动新疆社会经济的发展。依据城镇化的丰富内涵,选取复合指标体系,运用熵值法对新疆县域城镇化水平进行综合测度;结合GIS自然断裂点分类法,运用SPSS中的系统聚类对新疆县域城镇化水平进行了分类。结果表明：新疆县域城镇化水平空间差异明显,北疆县域综合城镇化水平高于南疆县域综合城镇化水平,综合城镇化水平的高值区呈现出“东北-西南”一线方位上,呈倒“U”型分布,而西北、东南方位则成为城镇化发展水平的“洼地”;从城镇化所包含的四个方面来看,北疆的人口城镇化、经济城镇化、地域景观城镇化均高于南疆同类城镇化水平,而在社会城镇化方面南疆则高于北疆。新疆县域综合城镇化水平并没有表现出集聚的特征,随机分布明显。把新疆县域城镇化水平划分为五类,这五种类型分别是：高城镇化水平类型区、中高城镇化水平类型区、中等城镇化水平类型区、中低城镇化水平类型区和低城镇化水平类型区。最后对影响县域城镇化发展水平的因素进行了分析。     

吉林省城镇化时空差异及协调发展研究

基于吉林省各县市2005—2014年人口和经济数据,采用探索性空间数据分析(ESDA)方法从整体及局部研究各县市人口城镇化和经济城镇化的时空差异,同时采用协调发展度模型探究城镇化协调发展及空间演化情况。结果表明:吉林省县市间城镇化水平总体空间差异逐步缩小,城镇化发展联系日益紧密;城镇化水平总体空间格局稳定,东西部与中部相比,空间格局稳定且空间差异较小;多数县市在研究前期和中期城镇化发展不协调,末期协调型县市较多,人口城镇化滞后是城镇化发展不协调的主要原因;协调型县市主要分布在东部,不协调型县市主要分布在中西部,县市的协调类型倾向于向更加协调的类型方向变化。     

近25 a甘肃省人口分布的时空格局及影响因素

人口分布是在一定时间、一定地域范围人口在空间上的表现,它会受社会、经济、自然和政策等多种因素影响,甘肃省人口分布处于不平衡状态。以甘肃省86个县域及嘉峪关市共87个研究单元为对象,常住人口数据为基础,对研究区1990—2015年之间人口的分布特征、密度变化、分布结构指数、基尼系数、重心迁移等时空格局变化进行了分析。以县域为研究单元,选取12个自然和社会经济因素,利用偏最小二乘法(PLS)对影响甘肃省人口分布空间格局的因素进行分析。研究发现:(1)近25 a来甘肃省人口空间分布差异显著,形成"东南密集西北稀疏"格局;(2)从人口密度变化来看,相较于1990年,2015年甘肃省87个研究单元中,有67个县域属于增加类型,20个县域属于降低类型;(3)全省人口分布的均衡性发展态势在增强;(4)人口分布的重心逐渐向西北方向迁移;(5)甘肃省人口分布格局的形成受自然因素与社会经济因素的同时影响,但社会经济因素影响最大。     

县域城镇化水平综合测评及其动力构成分析——以河北省为例

构建县域城镇化综合测评指标体系,包含经济城镇化、就业城镇化、市场城镇化、人口和基础设施城镇化.运用熵值法测算了河北省县域城镇化水平,发现2001-2012年县域城镇化水平处在上升状态,主要表现为人口城镇化、基础设施和农村非农就业的改变,但城镇化发展并未提供较多的城镇就业岗位和促进工业企业营利能力的提升.从多年平均看,人口和基础设施子系统对县域城镇化水平贡献份额最大,市场子系统贡献份额最小,各子系统有不同的时段特征.采用多元回归模型分析了影响县域城镇化水平的动力因素,显示推动力呈现多元化特点,各种动力共同助推县域城镇化水平的提高,但动力大小有差异,依次表现为政府动力、市场动力、社会动力.

Deserts and Aeolian Desertification in China: Book review and some thoughts

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.

THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.
