【摘要】：自步入新千年以來,我國城市化進程加速推進,城市土地利用格局正經(jīng)歷著一場大變革。城市建設(shè)用地的增長與耕地、林地面積的縮減成了城市空間變化過程中最顯著的特征。武漢市作為我國中部核心城市,是“中部崛起”的焦點城市,近年來經(jīng)濟社會得到飛速發(fā)展,建設(shè)用地需求也隨之加大。武漢市主城區(qū)外圍的城市空間擴展迅速,但區(qū)域內(nèi)的人口、資源、環(huán)境問題也日益突出。在此背景下進行關(guān)于都市發(fā)展區(qū)的空間擴展研究顯得十分重要。本文以武漢市都市發(fā)展區(qū)為研究對象,既包括7個主城區(qū)又包括發(fā)展迅速的城市外圍區(qū)。本研究以2000、2005、2010和2015年四期土地利用數(shù)據(jù)為依據(jù),進而通過土地利用動態(tài)度、土地利用綜合程度指數(shù)等方法解析了過去15年間研究區(qū)土地空間格局演變的總體情況,接著采用城市建設(shè)用地擴展的不同參數(shù)、重心轉(zhuǎn)移模型、方位象限分析法、擴展形態(tài)、擴展模式等方法從多角度深入研究了武漢市建設(shè)用地擴展的時空特征。最后,結(jié)合2010-2020年武漢市城市總體規(guī)劃,以2010年為基年,2015年為評價年,2020年為目標年,從重心遷移一致性、空間擴展一致性和空間布局一致性三個方面分析現(xiàn)階段建設(shè)用地擴展與城市規(guī)劃的一致性,以此揭示規(guī)劃在城市空間擴展中的指導作用,發(fā)現(xiàn)目前城市發(fā)展中存在的問題,為城市合理發(fā)展提出有益的建議。研究得出如下結(jié)論:(1)2000-2015年這15年間研究區(qū)內(nèi)各地類的數(shù)量結(jié)構(gòu)發(fā)生較大的變化,最顯著的是建設(shè)用地大幅度增長,增加值達55304公頃,而耕地、林地、水域及未利用地面積存在不同程度的減少,其中耕地面積減少最多,達49303.8公頃。這說明耕地與建設(shè)用地之間的矛盾成為城市空間擴展演化的主要特征。此外,水域面積數(shù)量起伏變化,總體趨于減少;草地波動變化,面積略有增加。這表明城市建設(shè)用地擴展壓縮了本底生態(tài)空間,環(huán)境壓力加大。(2)武漢市城市擴展在時間和空間上呈現(xiàn)出明顯的差異。從建設(shè)用地增長數(shù)量來看,2005-2010年和2010-2015年建設(shè)用地面積增長速度高于2000-2005年,擴展動態(tài)度、擴展強度也顯著上升。從各象限分異來看,2000-2015年,SEE和NNW建設(shè)用地擴展強度較為突出。從重心遷移來看,建設(shè)用地的重心具有不穩(wěn)定性,2000-2005年向西南遷移,2005-2010年向東南遷移,2010-2015年繼續(xù)向東南遷移,遷移速度先減少后增大。從城市形態(tài)變化來看,研究期時間范圍內(nèi)建設(shè)用地緊湊度指數(shù)值一直處于較低狀態(tài),說明城市建設(shè)用地布局較為松散。研究期時間范圍內(nèi)建設(shè)用地緊湊度值先變大后變小,表示城市輪廓由緊湊向松散發(fā)展。建設(shè)用地分形維數(shù)值先升后降且穩(wěn)定性系數(shù)先下降后略有回升,說明城市空間發(fā)展變得更加規(guī)則和更加穩(wěn)定。(3)武漢市都市發(fā)展區(qū)建設(shè)用地擴展模式演化特征:2000-2015年間蔓延式擴展始終占據(jù)主導地位,目前建設(shè)用地擴展仍然以蔓延為主。從時間演化過程來看,前期填充式擴展使主城區(qū)城市用地趨于飽和,飛地式擴展隨之加速進行,帶動了城市用地向外圍的進一步發(fā)展,為蔓延式擴展提供了空間。從空間分布的差異性來看,蔓延式擴展的熱點地區(qū)是江夏區(qū)和洪山區(qū);填充式擴展主要發(fā)生在主城區(qū),但有向外圍推進的趨勢;飛地式擴展始終集中于主城區(qū)外圍,尤其是江夏區(qū)、東西湖區(qū)和黃陂區(qū)。武漢市都市發(fā)展區(qū)逐漸呈現(xiàn)出“中心主城+六大衛(wèi)星城”的空間格局。(4)武漢市都市發(fā)展區(qū)建設(shè)用地擴展與城市規(guī)劃一致性研究結(jié)果表明:2010-2015年間城市空間重心遷移方向基本符合城市規(guī)劃預期方向,但是遷移速度略慢;在城市空間發(fā)展方向上,NEE方向由于自然條件受限,發(fā)展不足外,其余各向發(fā)展勢頭良好,城市空間初步呈現(xiàn)“中心主城+六大衛(wèi)星城”格局;在空間布局一致性上,各功能用地擴展速度快與規(guī)劃安排,建成率較高,但空間吻合率整體較低。
[Abstract]:Since the new millennium, the process of urbanization in China has accelerated, and the urban land use pattern is undergoing a great change. The growth of urban construction land and the reduction of cultivated land and the reduction of woodland area have become the most significant characteristics in the process of urban spatial change. As the central city of Central China, Wuhan is the focus city of "the rise of the central region". In recent years, the economic society has developed rapidly and the demand for construction land is also increasing. The expansion of the urban space outside the main urban area of Wuhan is rapid, but the population, resources and environmental problems in the region are becoming increasingly prominent. In this context, it is very important to carry out the Research on the expansion of the Urban Development Zone in this context. This paper is based on the urban development area of Wuhan. For the research object, it includes 7 main urban areas and the rapid development of urban peripheral areas. This study, based on the four period land use data of 200020052010 and 2015, analyzed the overall situation of the land spatial pattern evolution in the past 15 years through the land use dynamics and the index of land utilization comprehensive degree. Using the different parameters of the expansion of urban construction land, the model of gravity transfer, the azimuth quadrant analysis, the extended form and the expansion mode, the spatial and temporal characteristics of the expansion of the construction land in Wuhan are studied from many angles. Finally, in combination with the overall planning of the city of Wuhan for 2010-2020 years, the year 2010 is the basic year, the 2015 is the evaluation year, and the 2020 is the eye. In the year, from the three aspects of the consistency of the center of gravity migration, the consistency of space expansion and the consistency of the spatial layout, this paper analyzes the consistency between the expansion of the construction land use and the urban planning at the present stage, in order to reveal the guiding role of the planning in the expansion of the urban space, and find the problems existing in the current urban development, and put forward some useful suggestions for the rational development of the city. The following conclusions are drawn as follows: (1) there is a great change in the quantitative structure of the class in the study area during the 15 years of the 2000-2015 years. The most significant is that the construction land is greatly increased and the increase value reaches 55304 hectares, while the cultivated land, the woodland, the water area and the unused land have decreased in varying degrees, among which the area of cultivated land is reduced to a maximum of 49303.8 hectares. The contradiction between the cultivated land and the construction land has become the main feature of the urban space expansion and evolution. In addition, the amount and fluctuation of the area of the water area fluctuates, and the total area tends to decrease. The fluctuation of the grassland has a slight increase. This indicates that the urban construction land expands and compresses the ecological space, and the pressure of the environment is increased. (2) the expansion of the city in Wuhan is in time and space. From the number of construction land growth, the growth rate of construction land area in 2005-2010 and 2010-2015 years is higher than 2000-2005 years, the expansion dynamics and the expansion strength also rise significantly. From the point of view of the quadrant, the expansion intensity of the construction land for SEE and NNW is more prominent. The center of gravity of the land is unstable, migrated to the southwest in 2000-2005 years, migrated to the southeast in 2005-2010 years, and continued to migrate to the southeast in 2010-2015 years. The speed of migration was reduced first and then increased. In the period of study, the compactness of construction land in the period of study time becomes larger and then smaller, which indicates that the urban contour is developed from compact to loose. The fractal dimension value of the construction land first rises and then decreases and the stability coefficient decreases slightly after the decrease, which indicates that the development of urban space becomes more regular and more stable. (3) the expansion of the urban development area of Wuhan city is expanded. The evolution characteristics of the exhibition model: the spread expansion has always dominated in the 2000-2015 years. At present, the expansion of the construction land is still dominated by the spread. From the time evolution process, the early filling expansion makes the urban area of the main urban area become saturated and the expansion of the enclave style accelerates, driving the further development of the urban land to the periphery. Extending extension provides space. From the difference of spatial distribution, the hot areas of spread extension are Jiangxia and Hongshan; filling expansion mainly occurs in the main city, but there is a trend towards the periphery; the expansion of the enclave is always concentrated on the periphery of the main city, especially in Jiangxia, the East and West and Huangpi. The urban development of Wuhan city. The spatial pattern of "central city + six big satellite city" is gradually presented in the area. (4) the results of the research on the consistency of urban development area expansion and urban planning in Wuhan Urban Development Zone show that the migration direction of urban space center of gravity is basically in line with the expected direction of urban planning during the period of 2010-2015 years, but the migration speed is slightly slow; in the direction of urban space development, NEE Because of the limited natural conditions and lack of development, the rest of the development momentum is good. The urban space initially presents the pattern of "central city + six big satellite city". In the consistency of space layout, the expansion rate of each function is faster and the construction rate is higher, but the rate of space anastomosis is low.
