【摘要】：城市化是全球土地利用和覆蓋變化的重要內(nèi)容,對(duì)生態(tài)系統(tǒng)的組成、結(jié)構(gòu)和功能產(chǎn)生了巨大的影響。通過研究城市系統(tǒng)的格局來(lái)揭示城市化過程的規(guī)律,是在景觀水平上研究城市化的主要途徑,利用遙感、地理信息系統(tǒng)等空間信息技術(shù)能有效地監(jiān)測(cè)城市空間的擴(kuò)展情況。城市化過程在景觀上主要表現(xiàn)為其他各種土地利用類型向聚落的轉(zhuǎn)變。城市聚落粒級(jí)結(jié)構(gòu)表現(xiàn)為聚落系統(tǒng)中不同大小聚落斑塊的組成、結(jié)構(gòu)狀況,反映了城市空間結(jié)構(gòu)。一般可用等級(jí)規(guī)模結(jié)構(gòu)和位序規(guī)模結(jié)構(gòu)來(lái)描述聚落粒級(jí)結(jié)構(gòu)。不同區(qū)域、處于不同發(fā)展階段的城市的聚落粒級(jí)結(jié)構(gòu)通常有所差異,一般可分為均衡結(jié)構(gòu)和非均衡結(jié)構(gòu),首位分布是非均衡結(jié)構(gòu)中的一種。研究聚落粒級(jí)結(jié)構(gòu)及其演化規(guī)律有助于從景觀水平上理解城市化過程和城市景觀格局動(dòng)態(tài),有助于進(jìn)一步認(rèn)識(shí)城市化規(guī)律。蘇州、無(wú)錫和常州地區(qū)地處經(jīng)濟(jì)、文化水平發(fā)展較快的長(zhǎng)三角區(qū)域,是我國(guó)城市化水平較高、城鎮(zhèn)分布最密集的區(qū)域之一,也是城市化進(jìn)程最為劇烈的區(qū)域之一�？焖俪鞘谢^程導(dǎo)致了城市景觀格局發(fā)生了巨大的變化。研究蘇錫常地區(qū)城市化過程中聚落動(dòng)態(tài)變化對(duì)我國(guó)城市化過程的研究具有參考意義。為在區(qū)域及縣市尺度上揭示快速城市化過程中聚落異速增長(zhǎng)過程、聚落景觀粒級(jí)結(jié)構(gòu)及其演化過程的規(guī)律,本文利用1987、1993、1999、2005和2011年的Landsat遙感影像,提取江蘇蘇錫常地區(qū)3個(gè)地級(jí)市及9個(gè)縣級(jí)市行政單元的聚落用地,對(duì)區(qū)域及各縣市聚落的位序-規(guī)模結(jié)構(gòu)進(jìn)行分析,并將聚落斑塊按5、5-20、20～80、80～320、320～1280、1280～5120、5120～20480和≥20480 hm2分為8個(gè)粒級(jí),對(duì)各行政單元聚落粒級(jí)結(jié)構(gòu)特征及其演化過程進(jìn)行了比較研究。結(jié)果顯示：1)1987-2011年,研究區(qū)聚落總體規(guī)模增長(zhǎng)了約5倍,不同區(qū)域聚落規(guī)模的變化過程存在一定的節(jié)律性差異,各行政單元GDP以指數(shù)形式快速增長(zhǎng),聚落擴(kuò)展強(qiáng)度與GDP相對(duì)增長(zhǎng)率的變化節(jié)律存在差異；2)區(qū)域及各縣市聚落規(guī)模分布均符合位序-規(guī)模分布,1987-2005年區(qū)域10ha規(guī)模以上斑塊數(shù)量不斷增加,2005-2011年數(shù)量減少；區(qū)域及各行政單元Zipf維數(shù)均不斷增大,聚落規(guī)模差異均有增大趨勢(shì)；3)各行政單元聚落粒級(jí)數(shù)增長(zhǎng)了1-2級(jí),最低粒級(jí)聚落斑塊的面積占比大幅減小,最高粒級(jí)聚落的面積占比逐漸增大；在地級(jí)市單元及部分縣級(jí)市單元中,出現(xiàn)次高粒級(jí)面積占比較小甚至缺失現(xiàn)象；4)地級(jí)市單元聚落粒級(jí)結(jié)構(gòu)的均衡度較低,且持續(xù)下降,為非均衡分布型；而多數(shù)縣級(jí)市單元聚落粒級(jí)結(jié)構(gòu)的均衡度相對(duì)較高,且呈上升趨勢(shì),屬均衡分布型�？傮w上,蘇錫常地區(qū)聚落規(guī)模差異呈增大趨勢(shì),地級(jí)市聚落粒級(jí)結(jié)構(gòu)均衡度較低,而多數(shù)縣級(jí)市的均衡度較高。比較均衡分布型與非均衡分布型行政單元的區(qū)位條件及單元內(nèi)景觀資源格局特征發(fā)現(xiàn),域內(nèi)資源分布格局應(yīng)是影響聚落粒級(jí)結(jié)構(gòu)特征及其演化趨勢(shì)的重要原因。
[Abstract]:Urbanization is an important part of the global land use and cover change. It has a great influence on the composition, structure and function of the ecosystem. Through the study of the pattern of the urban system to reveal the law of the urbanization process, it is the main way to study the urbanization at the landscape level, using remote sensing, geographic information system and other spatial information technology. The urbanization process can effectively monitor the expansion of urban space. The urbanization process is mainly manifested in the transformation of various types of land use types to the settlement. The urban agglomeration grain level structure is represented by the composition of different sizes of settlement patches in the settlement system, the structure state, and the urban space structure. The size structure is used to describe the particle size structure. In different regions, the urban agglomeration structure in different stages of development is usually different, which can be divided into equilibrium structure and unbalanced structure. The first distribution is one of the non equilibrium structures. The study of the particle size structure and its evolution rules can help to understand the urbanization from the landscape level. The dynamic process and urban landscape pattern will help to further understand the law of urbanization. The Yangtze River Delta region, which is located in Suzhou, Wuxi and Changzhou, is one of the most intensive regions in China, and is also one of the most intensive urbanization areas. Great changes have taken place in the urban landscape pattern. The study of the dynamic change of settlement in the process of urbanization in Suzhou tin Chang area has a reference significance for the study of the process of urbanization in China. This paper uses Landsat remote sensing images of 1987199319992005 and 2011 to extract the settlement land of 3 prefectural cities and 9 county administrative units in Suzhou Changzhou, Jiangsu, and analyzes the sequence scale structure of the areas and counties and cities, and the settlement patches are 5,5-20,20 to 80,80 ~ 320320~12801280 ~ 51205120~20480 and more than 20480. Hm2 is divided into 8 grain levels, and a comparative study is made on the characteristics and evolution process of the aggregate grain grade structure of each administrative unit. The results show that: 1) 1987-2011 years, the overall size of the settlement in the study area has increased by about 5 times. There are some rhythmic differences in the change process of the settlement scale in different regions, and the administrative unit GDP increases rapidly in the form of index. There are differences in the variation rhythm of the expansion intensity and the relative growth rate of GDP. 2) the size distribution of the areas and counties and cities conforms to the order scale distribution. The number of patches above the scale of 10ha increases continuously in 1987-2005 years, the number of 2005-2011 years decreases, and the number of Zipf dimensions in the region and the administrative units are increasing, and the differences in the settlement scale have increased. Potential; 3) the number of settlement grains of each administrative unit increased by 1-2 levels, the area occupation ratio of the lowest particle size settlement patches was greatly reduced, the area of the highest grain level settlement increased gradually; in the units of the city and some county-level city units, the sub high grain size was smaller and even lost, and 4) the level structure of the unit settlement grain of the city level city unit In most county-level city units, the equilibrium degree of the aggregate grain level structure is relatively high and is on the rise, which is a balanced distribution type. On the whole, the settlement scale difference of the Suzhou tin region is increasing, the equilibrium degree of the grain level structure in the prefecture level city is low, and the equilibrium degree of most county-level cities is higher. It is found that the distribution pattern of resources in the domain should be an important factor affecting the characteristics and evolution trend of the particle size structure and its evolution trend by comparing the location conditions of the equilibrium distribution and non equilibrium distribution type administrative units and the characteristics of the landscape resource pattern in the unit.
