【摘要】：我国正处在城市化快速发展阶段,随着经济发展和各项城市建设活动的推进,城市扩张相关指数作为反映城市化发展水平快慢的载体和量化指标,目前已成为近几年来土地利用/土地覆被变化(LUCC)研究的重要领域。攀西城市群作为四川省辐射西部、面向全国、融入世界的“四大城市群”之一,其既是连结成都、昆明等地的“西四角”和连接东南亚的门户,也是成渝经济区群向西南方向发展的重要辐射区;同时作为西部典型“资源型”城市群与四川省重要经济增长极,攀西城市群在地理区位和经济发展上均具有显著战略地位。本文以攀西城市群及其核心城市作为研究区,从以下三方面展开研究:(1)基于DMSP夜间灯光影像和相关统计数据,采用阈值二分法对核心城市用地信息进行提取,将1993-2013年划分为5个时间段分析核心城市用地扩张的空间动态变化,总结城市扩张特征和规律。(2)从自然条件因素、规划导向及交通因素、政策、社会经济因素四方面研究攀西城市群核心城市扩张驱动力机制,其中从社会经济因素方面选取8个与城市扩张有密切联系的指标,利用灰色关联度法定量研究该指标与核心城市扩张的关联度。(3)基于对攀西城市群核心城市扩张情况及驱动机制分析结果,在综合驱动因子共同作用下对核心城市未来城市空间发展趋势做出预测并提出相关策略。本文基于宏观角度范围内对城市用地空间信息提取的基础上,获取城市群城市空间格局变化情况、城市用地扩张情况、城市用地扩张驱动力等研究结果,揭示该区域城镇化发展水平,为未来城市空间扩展方向和趋势提供历史性依据;同时,也为决策者指导城市可持续发展、资源型城市的科学转型、紧凑城市的建设等提供数据支撑和依据,对促进攀西地区健康、合理、持续发展具有重要意义。主要研究结论如下:(1)从区域尺度上,1993-2013年期间,整个攀西城市群已基本形成以攀枝花为核心的发展集群,整体空间发展格局沿着铁路和高速路呈线状发展模式,形成“攀枝花市与西昌市为核心城市、安宁河谷地区为都市核心区”的发展集群雏形;同时攀枝花和西昌市周围的卫星城市呈点状发展态式,促进了郊区周围小城市之间的互动。(2)从城市尺度上,1993-2013年期间,攀枝花市和西昌市城市扩张年增长速度分别为1.56km2/a、0.53km2/a;根据年扩张动态度和扩张强度分析结果,攀枝花和西昌市城市发展从2003年开始均进入加速扩张阶段,大量的非城市用地转为城市用地。(3)通过城市空间差异及质心转移,分析其结果可以发现:攀西城市群(攀枝花市和西昌市)1993-2013年城市扩张在空间上有不同发展模式和质心转移、移动方向、移动幅度均有较大不同。攀枝花城市发展沿金沙江呈带状式往东南方向发展,主要与钒钛产业、电冶化工产业等产业发展有关;西昌市呈现中心向四周发展的面状式往西北方和东南方发展,主要与商业金融区、商务行政办公中心区、居住区等建设有关。(4)从攀西城市群扩张驱动力分析结果可知,自然条件因素是城市扩张的基础;规划导向与政策因素将直接影响城市发展空间;交通因素间接引导城发展方向;社会经济因素是城市扩张的主要驱动力,其中国内生产总值、建筑业总产值与非农业人口三个因子与攀枝花市城市扩张具有高关联度,国内生产总值、第二产业与第三产业三个因子与西昌市城市扩张具有高关联度。(5)未来攀西城市群空间扩张的趋势将形成“多核、一区、多点”的空间布局结构;攀枝花市将以“都市环+多中心放射组团”式结合方式发展;西昌市将以“轴向式+单中心团块”式结合模式发展。(6)在“资源型城市转型”背景下,攀枝花市未来空间发展策略主要以“产业调整+城市形象提升+合理控制”为主;西昌市主要以“城市空间优化+产业整合”为主。
[Abstract]:Our country is in a stage of rapid development of the city, along with the development of economy and the city construction activities to promote the city expansion related index as the carrier and quantitative indicators of the level of development speed of the city, has become in recent years the land use / land cover change (LUCC) is an important research field. The Panxi city group as the radiation of Sichuan Province West, facing the country, into the world of the "four big city group" is one of the links is Chengdu, Kunming and other places of the "quadrangle" and the connection of the gateway to Southeast Asia, but also the Chengdu Chongqing Economic Zone group to the South West important radiation zone development; at the same time as the typical western resource type city group and Sichuan province is an important economic growth pole, Panzhihua City Group in the geographical location and economic development has a significant strategic position. In this paper, Panxi city group and its core city as the study area, from the following three aspects Study: (1) the DMSP nighttime light data and related statistical data based on the threshold of the core city of dichotomy of land information extraction, 1993-2013 years will be divided into 5 periods of space dynamic change analysis of the core city land expansion, summarize the characteristics and rules of city expansion. (2) from natural factors, policy the planning guidance and traffic factors, social economic factors, the four aspects of the core city west city climbing group extension mechanism of driving force, which is selected from the 8 aspects of social and economic factors and expansion of the city is closely linked to the index, correlation of this index with the core city expansion using quantitative grey correlation method (3) of the. Panzhihua City West City Group core expansion and driving mechanism based on the results of the analysis in the comprehensive factors of the core city of the future city spatial development trend forecast and put forward related strategies. This paper is based on the macroscopic angle range of city land spatial information extraction, obtain the change pattern of city space city group, city land expansion, city land expansion force results, reveal the development level of urbanization in the region, provide the historical basis for the future direction and trend of city spatial expansion; at the same time also, for decision makers to guide the city sustainable development, scientific transformation of Resource-based City, compact city construction to provide data support and basis, to promote the healthy and sustainable development in Panxi area is reasonable, has important significance. The main conclusions are as follows: (1) from the regional scale, a period of 1993-2013 years, the whole city Panxi the group has formed a cluster development in Panzhihua as the core, the overall spatial development pattern along the railway and highway linear development model, the formation of "Panzhihua city and Xichang city as the core of the city City of Anning River area for the development of the core area of the city cluster "; satellite around the city and Panzhihua and Xichang city were dot development to promote the interaction between the state and the surrounding suburban small city. (2) from the city scale, a period of 1993-2013 years, Panzhihua city and Xichang city to expand the annual growth rate respectively. 1.56km2/a, 0.53km2/a; according to the results of years of expansion and expansion of dynamic strength of Panzhihua and the development of Xichang city was entered the accelerated expansion phase from 2003, a large number of non city land to city land. (3) the city spatial difference and centroid transfer, analysis of the results can be found: (Panzhihua Xichang city group Panzhihua city and Xichang city) 1993-2013 years of city expansion have different development models and mass transfer, in the space direction, moving amplitude is different. The development of Panzhihua city along the Jinsha River strip type To the southeast direction, and the main vanadium titanium industry, chemical industry and other related industry development project; Xichang city is the center of development to the development of the area around the north and southeast of West type, the main business and Financial District, business district administrative office center, the construction of residential area. (4) from Panzhihua Xichang city expansion drive stress analysis results, natural factors is the basis of city expansion; the planning guidance and policy factors will directly affect the development of city space; traffic factors indirectly guide city development direction; social and economic factors are the main driving force of city expansion, including GDP, gross output value of construction industry and non agricultural population three factors and the city of Panzhihua city expansion with high degree of association, GDP, three factor second and third industry and urban expansion in Xichang city with high correlation. (5) the future expansion of space group climbing West City The trend will form a "multi core, area, space layout structure"; Panzhihua city will be the urban ring + multi center radiation group "type combination development; Xichang city will combine the development pattern of" axial + single center mass ". (6) in the" resource-based city transformation "under the background of Panzhihua City, the future space development strategy mainly to enhance the image of the city industry adjustment + + reasonable control"; the main city of Xichang to the "city space optimization and industrial integration".
