【摘要】：城鎮(zhèn)群是城鎮(zhèn)化過(guò)程中出現(xiàn)的一種地域空間組織形式，是城鎮(zhèn)集聚與擴(kuò)散的一種高級(jí)現(xiàn)象，已經(jīng)成為發(fā)達(dá)國(guó)家和地區(qū)城鎮(zhèn)化的重要趨勢(shì)之一。20世紀(jì)80年代以來(lái)，隨著西部大開(kāi)發(fā)戰(zhàn)略的實(shí)施，西部省份的經(jīng)濟(jì)得到快速增長(zhǎng)，同時(shí)城市也進(jìn)入快速增長(zhǎng)階段。酒泉-嘉峪關(guān)地區(qū)在古代是中原王朝的西大門，河西走廊的西段口，在現(xiàn)代是連接甘肅與新疆、青海、內(nèi)蒙古等地的樞紐，具有重要的地理區(qū)位優(yōu)勢(shì)和發(fā)展經(jīng)濟(jì)優(yōu)勢(shì)。完善酒泉-嘉峪關(guān)城鎮(zhèn)群結(jié)構(gòu)，將更好地發(fā)揮城鎮(zhèn)群整體經(jīng)濟(jì)優(yōu)勢(shì)，提升城鎮(zhèn)群的競(jìng)爭(zhēng)力，促進(jìn)區(qū)域經(jīng)濟(jì)的可持續(xù)發(fā)展。 筆者在閱讀大量相關(guān)文獻(xiàn)、資料之后分析了城鎮(zhèn)群的概念以及其國(guó)內(nèi)外相關(guān)研究進(jìn)展，從現(xiàn)實(shí)和理論兩個(gè)角度闡述了論文的選題背景和研究意義，在介紹本文的主要方法之后引出了技術(shù)路線。在國(guó)情基礎(chǔ)之上結(jié)合甘肅省的實(shí)際情況，界定了酒泉—嘉峪關(guān)城鎮(zhèn)群的范圍，并從自然條件、人文環(huán)境、社會(huì)和經(jīng)濟(jì)發(fā)展?fàn)顩r等對(duì)研究區(qū)域的概況進(jìn)行描述，以此作為文章研究的基礎(chǔ)，展開(kāi)空間成長(zhǎng)規(guī)模統(tǒng)計(jì)分析，進(jìn)而進(jìn)行空間結(jié)構(gòu)特征進(jìn)行研究。 本文在進(jìn)行空間成長(zhǎng)規(guī)模分析時(shí)首先利用遙感技術(shù)對(duì)研究區(qū)域的遙感影像進(jìn)行解讀，提取城鎮(zhèn)用地?cái)?shù)據(jù)，并結(jié)合GIS技術(shù)分析區(qū)域的城市擴(kuò)展變化，然后利用區(qū)域內(nèi)的相關(guān)人口數(shù)據(jù)，通過(guò)地統(tǒng)計(jì)分析法研究區(qū)域內(nèi)的城鎮(zhèn)化分布以及人口空間分布。研究發(fā)現(xiàn)近20年來(lái)酒-嘉城鎮(zhèn)群地區(qū)以片狀蔓延式從中心城鎮(zhèn)向四周擴(kuò)展；研究區(qū)域內(nèi)的城鎮(zhèn)化水平分布具有明顯的主軸特點(diǎn)，以鐵路和312國(guó)道為主線的周邊城鎮(zhèn)近10年來(lái)城鎮(zhèn)化水平較高，，發(fā)展迅速，且發(fā)展具有明顯的產(chǎn)業(yè)指向性。 在此研究成果基礎(chǔ)之上，結(jié)合分形理論，利用關(guān)聯(lián)維數(shù)模型測(cè)算出城鎮(zhèn)群空間分維數(shù)，發(fā)現(xiàn)研究區(qū)域在空間分布上比較集中，雖然個(gè)別城鎮(zhèn)之間通達(dá)系數(shù)較低，但就整個(gè)區(qū)域而言具有較高的集聚性。
[Abstract]:Urban cluster is a form of regional spatial organization in the process of urbanization, a high-level phenomenon of urban agglomeration and diffusion, and has become one of the important trends of urbanization in developed countries and regions since 1980s. With the implementation of the strategy of developing the western region, the economy of the western provinces has been growing rapidly, and the cities have also entered the stage of rapid growth. Jiuquan-Jiayuguan area is the west gate of the Central Plains Dynasty in ancient times and the west entrance of the Hexi Corridor. In modern times, it is the hub connecting Gansu with Xinjiang, Qinghai, Inner Mongolia and so on. It has important geographical location advantage and economic development advantage. Perfecting the structure of Jiuquan-Jiayuguan town group will bring into play the whole economic advantage of the town group, promote the competitiveness of the town group, and promote the sustainable development of the regional economy. After reading a large number of relevant documents and materials, the author analyzes the concept of urban group and its related research progress at home and abroad, and expounds the background and significance of the thesis from the perspective of reality and theory. After introducing the main methods of this paper, the technical route is introduced. Based on the actual situation of Gansu Province, this paper defines the scope of Jiuquan-Jiayuguan Town Group, and describes the general situation of the study area from the aspects of natural conditions, humanistic environment, social and economic development, etc. On the basis of this research, the spatial growth scale is analyzed statistically and the spatial structure characteristics are studied. In this paper, we first use remote sensing technology to interpret the remote sensing image of the study area, extract the urban land data, and analyze the urban expansion changes with GIS technology. Then the distribution of urbanization and population spatial distribution in the region are studied by using the relevant population data of the region and the geostatistical analysis method. It is found that in the past 20 years, the Jiu-Jia Town Group has spread from the central town to the surrounding area in a patchy manner, and the urbanization level distribution in the study area has obvious characteristics of the main axis. The surrounding towns with railway and 312 national highway as the main line in the past 10 years, the urbanization level is relatively high, the development is rapid, and the development has obvious industrial orientation. Based on the research results and fractal theory, the fractal dimension of urban groups is calculated by using the correlation dimension model. It is found that the spatial distribution of the study area is relatively concentrated, although the coefficient of access between individual towns is relatively low. However, the whole region has a high agglomeration.
