【摘要】：我國正處在城市化快速發(fā)展階段,隨著經(jīng)濟發(fā)展和各項城市建設活動的推進,城市擴張相關指數(shù)作為反映城市化發(fā)展水平快慢的載體和量化指標,目前已成為近幾年來土地利用/土地覆被變化(LUCC)研究的重要領域。攀西城市群作為四川省輻射西部、面向全國、融入世界的“四大城市群”之一,其既是連結成都、昆明等地的“西四角”和連接東南亞的門戶,也是成渝經(jīng)濟區(qū)群向西南方向發(fā)展的重要輻射區(qū);同時作為西部典型“資源型”城市群與四川省重要經(jīng)濟增長極,攀西城市群在地理區(qū)位和經(jīng)濟發(fā)展上均具有顯著戰(zhàn)略地位。本文以攀西城市群及其核心城市作為研究區(qū),從以下三方面展開研究:(1)基于DMSP夜間燈光影像和相關統(tǒng)計數(shù)據(jù),采用閾值二分法對核心城市用地信息進行提取,將1993-2013年劃分為5個時間段分析核心城市用地擴張的空間動態(tài)變化,總結城市擴張?zhí)卣骱鸵?guī)律。(2)從自然條件因素、規(guī)劃導向及交通因素、政策、社會經(jīng)濟因素四方面研究攀西城市群核心城市擴張驅動力機制,其中從社會經(jīng)濟因素方面選取8個與城市擴張有密切聯(lián)系的指標,利用灰色關聯(lián)度法定量研究該指標與核心城市擴張的關聯(lián)度。(3)基于對攀西城市群核心城市擴張情況及驅動機制分析結果,在綜合驅動因子共同作用下對核心城市未來城市空間發(fā)展趨勢做出預測并提出相關策略。本文基于宏觀角度范圍內對城市用地空間信息提取的基礎上,獲取城市群城市空間格局變化情況、城市用地擴張情況、城市用地擴張驅動力等研究結果,揭示該區(qū)域城鎮(zhèn)化發(fā)展水平,為未來城市空間擴展方向和趨勢提供歷史性依據(jù);同時,也為決策者指導城市可持續(xù)發(fā)展、資源型城市的科學轉型、緊湊城市的建設等提供數(shù)據(jù)支撐和依據(jù),對促進攀西地區(qū)健康、合理、持續(xù)發(fā)展具有重要意義。主要研究結論如下:(1)從區(qū)域尺度上,1993-2013年期間,整個攀西城市群已基本形成以攀枝花為核心的發(fā)展集群,整體空間發(fā)展格局沿著鐵路和高速路呈線狀發(fā)展模式,形成“攀枝花市與西昌市為核心城市、安寧河谷地區(qū)為都市核心區(qū)”的發(fā)展集群雛形;同時攀枝花和西昌市周圍的衛(wèi)星城市呈點狀發(fā)展態(tài)式,促進了郊區(qū)周圍小城市之間的互動。(2)從城市尺度上,1993-2013年期間,攀枝花市和西昌市城市擴張年增長速度分別為1.56km2/a、0.53km2/a;根據(jù)年擴張動態(tài)度和擴張強度分析結果,攀枝花和西昌市城市發(fā)展從2003年開始均進入加速擴張階段,大量的非城市用地轉為城市用地。(3)通過城市空間差異及質心轉移,分析其結果可以發(fā)現(xiàn):攀西城市群(攀枝花市和西昌市)1993-2013年城市擴張在空間上有不同發(fā)展模式和質心轉移、移動方向、移動幅度均有較大不同。攀枝花城市發(fā)展沿金沙江呈帶狀式往東南方向發(fā)展,主要與釩鈦產業(yè)、電冶化工產業(yè)等產業(yè)發(fā)展有關;西昌市呈現(xiàn)中心向四周發(fā)展的面狀式往西北方和東南方發(fā)展,主要與商業(yè)金融區(qū)、商務行政辦公中心區(qū)、居住區(qū)等建設有關。(4)從攀西城市群擴張驅動力分析結果可知,自然條件因素是城市擴張的基礎;規(guī)劃導向與政策因素將直接影響城市發(fā)展空間;交通因素間接引導城發(fā)展方向;社會經(jīng)濟因素是城市擴張的主要驅動力,其中國內生產總值、建筑業(yè)總產值與非農業(yè)人口三個因子與攀枝花市城市擴張具有高關聯(lián)度,國內生產總值、第二產業(yè)與第三產業(yè)三個因子與西昌市城市擴張具有高關聯(lián)度。(5)未來攀西城市群空間擴張的趨勢將形成“多核、一區(qū)、多點”的空間布局結構;攀枝花市將以“都市環(huán)+多中心放射組團”式結合方式發(fā)展;西昌市將以“軸向式+單中心團塊”式結合模式發(fā)展。(6)在“資源型城市轉型”背景下,攀枝花市未來空間發(fā)展策略主要以“產業(yè)調整+城市形象提升+合理控制”為主;西昌市主要以“城市空間優(yōu)化+產業(yè)整合”為主。
[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".
