【摘要】：土地是人類(lèi)生存與發(fā)展的資源基礎(chǔ),隨著城市的發(fā)展,對(duì)土地的需求量越來(lái)越大,由于人口的增加和對(duì)土地的不合理利用,出現(xiàn)土地生態(tài)環(huán)境的惡化,供需矛盾加劇,阻礙土地可持續(xù)利用等問(wèn)題。從而土地利用的動(dòng)態(tài)變化越來(lái)越被認(rèn)為是一個(gè)關(guān)鍵而迫切的研究課題。土地利用變化的動(dòng)態(tài)監(jiān)測(cè)以遙感信息作為數(shù)據(jù)源,具有周期性、廣域性、經(jīng)濟(jì)性等特點(diǎn),再結(jié)合地面輔助資料,借助計(jì)算機(jī)圖像處理技術(shù),對(duì)土地利用狀況及其動(dòng)態(tài)變化進(jìn)行全面系統(tǒng)地評(píng)估和分析。適時(shí)了解土地利用現(xiàn)狀和結(jié)構(gòu)變化,對(duì)于促進(jìn)土地合理利用,實(shí)現(xiàn)土地可持續(xù)發(fā)展具有重要意義。而城市群作為城市化發(fā)展的主要形態(tài),是實(shí)現(xiàn)資源集約利用的有效途徑之一,將在新型城鎮(zhèn)化發(fā)展建設(shè)中發(fā)揮著重要的作用。烏魯木齊城市群是一個(gè)正在形成中的干旱區(qū)綠洲城市群,烏魯木齊城市群在經(jīng)濟(jì)持續(xù)發(fā)展的同時(shí),城市空間也在不斷的發(fā)生變化。隨著城市擴(kuò)展速度的加快、交通及網(wǎng)絡(luò)的擴(kuò)張,該地區(qū)城鎮(zhèn)體系的空間分布格局以及土地利用方式等都發(fā)生了很大的變化。本文以烏魯木齊城市群(烏魯木齊市、昌吉市、阜康市、五家渠市、石河子)作為主要研究對(duì)象,通過(guò)解譯2000年、2006年、2013年烏魯木齊城市群中各城市的遙感影像,重點(diǎn)研究2000—2013年烏魯木齊城市群的土地利用變化狀況,并對(duì)烏魯木齊城市群土地利用動(dòng)態(tài)變化進(jìn)行綜合分析。結(jié)果如下:(1)從烏魯木齊城市群的土地利用類(lèi)型面積來(lái)看,2000年、2006年和2013年這三年中城市未利用地比重較大,這是由烏魯木齊城市群所處的地形決定的。烏魯木齊城市群中的烏魯木齊市由于受地形的限制,未利用地面積增速緩慢,而昌吉市、阜康市、五家渠市北部大部分在古爾班通古特沙漠,城市建設(shè)面積小,但隨著社會(huì)、經(jīng)濟(jì)、人口的快速發(fā)展,城市建設(shè)用地面積在不斷的增大,未利用地面積也在不斷的減少。(2)烏魯木齊城市群2000—2013年之間的土地利用變化比較大,從結(jié)果及變化幅度來(lái)看,城市建設(shè)用地的變化較為突出。而在城市建設(shè)用地變化中居住用地、工業(yè)用地以及公共設(shè)施用地所占比重有上升趨勢(shì)。(3)烏魯木齊城市群的土地利用變化主要受自然因素和人文因素的共同影響。概括起來(lái)主要有以下幾個(gè)方面:人口增長(zhǎng)、經(jīng)濟(jì)發(fā)展及產(chǎn)業(yè)結(jié)構(gòu)變化;此外,政策因素也是影響城市土地利用變化的一個(gè)重要因素。
[Abstract]:Land is the resource base of human existence and development. With the development of city, the demand for land is increasing. Because of the increase of population and unreasonable use of land, the deterioration of ecological environment of land and the intensification of contradiction between supply and demand. Obstacles to sustainable land use and other issues. Therefore, the dynamic change of land use is more and more regarded as a key and urgent research topic. In the dynamic monitoring of land use change, remote sensing information is used as data source, which has the characteristics of periodicity, wide area, economy and so on. Land use and its dynamic changes are comprehensively and systematically assessed and analyzed. It is of great significance to understand the present situation and structural change of land use in time to promote the rational use of land and to realize the sustainable development of land. As the main form of urbanization, urban agglomeration is one of the effective ways to realize intensive utilization of resources, which will play an important role in the development of new urbanization. Urumqi urban agglomeration is an oasis urban agglomeration in arid area. The urban space of Urumqi urban agglomeration is changing while the economy is developing continuously. With the acceleration of urban expansion and the expansion of traffic and network, the spatial distribution pattern and land use pattern of urban system in this area have changed greatly. In this paper, Urumqi urban agglomeration (Urumqi, Changji, Fukang, Wujiaqu, Shihezi) as the main research object, by interpreting the 2000, 2006, 2013 Urumqi urban agglomeration remote sensing images, This paper focuses on the land use change of Urumqi urban agglomeration from 2000 to 2013, and makes a comprehensive analysis on the land use dynamic change of Urumqi urban agglomeration. The results are as follows: (1) according to the land use area of Urumqi urban agglomeration, the proportion of unused land in 2000, 2006 and 2013 is large, which is determined by the topography of Urumqi urban agglomeration. Urumqi, in the Urumqi urban agglomeration, grows slowly due to the limitation of topography, while Changji City, Fukang City, and Wujiaku City are mostly in the Guerbantungote Desert. The urban construction area is small, but with the society, With the rapid development of economy and population, the area of urban construction land is increasing, and the area of unused land is also decreasing. (2) the land use change of Urumqi urban agglomeration from 2000 to 2013 is relatively large. The change of urban construction land is more prominent. However, the proportion of residential land, industrial land and public facilities land has an upward trend in the change of urban construction land. (3) the land use change of Urumqi urban agglomeration is mainly influenced by natural and human factors. In summary, there are the following aspects: population growth, economic development and industrial structure change; in addition, policy factors are also an important factor affecting urban land use change.
