【摘要】:自20世紀(jì)80年代以來(lái),人口的增長(zhǎng)、工業(yè)化城市化水平的提高等,人類對(duì)生產(chǎn)資料的需求量也成急劇增張的態(tài)勢(shì),人們正以空前的規(guī)模和速率對(duì)自然資源進(jìn)行開(kāi)發(fā)和利用。近年來(lái),烏魯木齊市正處于快速發(fā)展的階段,土地利用的深度、廣度和速度都發(fā)生很大的變化,這一時(shí)期人地矛盾逐漸突出。因此,對(duì)烏魯木齊市土地利用變化進(jìn)行研究是很有必要的。本文利用烏魯木齊市2005 2012年土地調(diào)查數(shù)據(jù),采用土地利用動(dòng)態(tài)模型、土地利用程度綜合指數(shù)模型對(duì)烏魯木齊市近8年來(lái)土地利用變化進(jìn)行定量分析。再利用主成份分析法和相關(guān)分析法對(duì)影響烏魯木齊市土地利用變化的驅(qū)動(dòng)因子進(jìn)行分析,通過(guò)研究,對(duì)烏魯木齊市未來(lái)土地資源利用的可持續(xù)利用提出對(duì)策建議。得出的主要結(jié)論有: (1)烏魯木齊市農(nóng)用地變化速度最快的是園地,烏魯木齊2012年土地利用程度相比2005年土地利用程度提高了,這說(shuō)明烏魯木齊市的土地利用正處于發(fā)展時(shí)期。從土地利用區(qū)域差異化分析結(jié)果來(lái)看,各區(qū)縣土地利用有明顯的差異。 (2)根據(jù)主成分分析結(jié)果可以看出,影響烏魯木齊市土地利用變化的主要因素是人口增長(zhǎng)和經(jīng)濟(jì)發(fā)展因素。從相關(guān)性研究可以看出,耕地面積變化與人口增長(zhǎng)、房地產(chǎn)投資開(kāi)發(fā)、固定資產(chǎn)總額和地區(qū)生產(chǎn)總值呈很強(qiáng)負(fù)相關(guān),說(shuō)明隨著這些因素增加,反而帶來(lái)耕地?cái)?shù)量減少。建設(shè)用地與人口增長(zhǎng)、非農(nóng)人口增加、交通運(yùn)輸用地增加和地區(qū)生產(chǎn)總值等經(jīng)濟(jì)發(fā)展因素呈正相關(guān),這些因素帶來(lái)建設(shè)用地面積擴(kuò)長(zhǎng)。 (3)針對(duì)烏魯木齊土地利用現(xiàn)狀及變化的趨勢(shì),政府首先加強(qiáng)對(duì)耕地實(shí)施保護(hù),,嚴(yán)格按照總體規(guī)劃安排用地,對(duì)建設(shè)用地的供地?cái)?shù)量要有所控制,加大存量土地的盤活力度。在發(fā)展經(jīng)濟(jì)的同時(shí),注重對(duì)土地資源的保護(hù),使二者協(xié)調(diào)發(fā)展。
[Abstract]:Since the 1980s, with the increase of population and the improvement of industrialization and urbanization, the demand for the means of production has increased rapidly, and people are exploiting and utilizing the natural resources on an unprecedented scale and at an unprecedented rate.In recent years, Urumqi is in the stage of rapid development. The depth, breadth and speed of land use have changed greatly.Therefore, it is necessary to study the land use change in Urumqi.Based on the land survey data of Urumqi in 2005 and 2012, the land use dynamic model and the comprehensive index model of land use degree are used to quantitatively analyze the land use change in Urumqi in the past 8 years.Then the main component analysis and correlation analysis are used to analyze the driving factors that affect the land use change in Urumqi. Through the research, the countermeasures and suggestions are put forward for the sustainable use of land resources in Urumqi.The main conclusions reached are:The land use in Urumqi in 2012 is higher than that in 2005, which indicates that the land use in Urumqi is in the developing period. 1) the change of agricultural land in Urumqi is the fastest, and the degree of land use in Urumqi in 2012 is higher than that in 2005, which indicates that the land use in Urumqi is in a developing period.According to the results of land use regional differentiation analysis, there are obvious differences in land use among districts and counties.2) according to the results of principal component analysis, the main factors affecting land use change in Urumqi are population growth and economic development.It can be seen from the correlation study that the change of cultivated land area has a strong negative correlation with population growth, real estate investment and development, total fixed assets and regional GDP, indicating that with the increase of these factors, the amount of cultivated land decreases.Construction land is positively related to population growth, non-agricultural population increase, transportation land increase and regional gross domestic product (GDP). These factors lead to the expansion of construction land area.In view of the present situation and changing trend of land use in Urumqi, the government first strengthens the protection of cultivated land, arranges the land strictly according to the overall plan, controls the quantity of land supply for construction land, and increases the vitality of the stock land.In the development of the economy, attention to the protection of land resources, so that the two coordinated development.
