【摘要】：自20世纪80年代以来，人口的增长、工业化城市化水平的提高等，人类对生产资料的需求量也成急剧增张的态势，人们正以空前的规模和速率对自然资源进行开发和利用。近年来，乌鲁木齐市正处于快速发展的阶段，土地利用的深度、广度和速度都发生很大的变化，这一时期人地矛盾逐渐突出。因此，对乌鲁木齐市土地利用变化进行研究是很有必要的。本文利用乌鲁木齐市2005 2012年土地调查数据，采用土地利用动态模型、土地利用程度综合指数模型对乌鲁木齐市近8年来土地利用变化进行定量分析。再利用主成份分析法和相关分析法对影响乌鲁木齐市土地利用变化的驱动因子进行分析，通过研究，对乌鲁木齐市未来土地资源利用的可持续利用提出对策建议。得出的主要结论有：（1）乌鲁木齐市农用地变化速度最快的是园地，乌鲁木齐2012年土地利用程度相比2005年土地利用程度提高了，这说明乌鲁木齐市的土地利用正处于发展时期。从土地利用区域差异化分析结果来看，各区县土地利用有明显的差异。（2）根据主成分分析结果可以看出，影响乌鲁木齐市土地利用变化的主要因素是人口增长和经济发展因素。从相关性研究可以看出，耕地面积变化与人口增长、房地产投资开发、固定资产总额和地区生产总值呈很强负相关，说明随着这些因素增加，反而带来耕地数量减少。建设用地与人口增长、非农人口增加、交通运输用地增加和地区生产总值等经济发展因素呈正相关，这些因素带来建设用地面积扩长。（3）针对乌鲁木齐土地利用现状及变化的趋势，政府首先加强对耕地实施保护，，严格按照总体规划安排用地，对建设用地的供地数量要有所控制，加大存量土地的盘活力度。在发展经济的同时，注重对土地资源的保护，使二者协调发展。
[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.
