【摘要】：土地利用变化研究已经成为当前的一大热点,研究这一课题对于促进区域可持续发展具有重要的现实意义。吉安市位于江西省中部,以山地为主,经济在全国属中等水平。由于经济的发展,吉安市土地利用变化发生了较大变化,对该区进行土地利用变化研究具有一定的指导意义。本文结合吉安市区域概况,分析了该区土地利用现状,以及1996—-2010年土地利用的动态变化,再从定性和定量两个角度分析了其变化的驱动力,接着在此基础上得出该区土地利用方面的一些特点和存在的问题,最后提出相关建议和对策,并提出展望。研究表明：(1)吉安市土地利用类型多样,利用类型以农用地为主,耕地仅次于林地,吉安市的土地利用模式中以林地占主体；吉安市各县(区、市)土地利用的多样化指数差异较大；(2)农用地和建设用地数量大幅增加,未利用地则减少；H为37.75%,2010年利用程度综合指数为228.18,说明吉安市土地利用处于发展期；吉安市土地利用仍然处于发展时期,土地利用程度变化率S=4.21%;吉安市的土地利用偏离度近几年小幅下滑,说明该区土地利用活动对自然景观干预有所下降。(3)通过驱动力定量和定性分析,得出气候、地形地貌、水文、土壤、人口、经济、技术进步是该区土地利用变化的大致原因,其中经济因素、人口因素和技术进步是社会经济驱动力方面的主要驱动力,而且驱动力逐年增强。(4)根据该区土地利用存在的问题提出了相应对策,并且提出了展望。全文共计七部分：第一部分是前言。第二部分是有关的计算方法。论文在借鉴已有研究的基础上,对相关理论进行了详细的阐述。第三部分主要介绍研究区的自然和社会经济状况,以及本文的数据来源和数据处理方法。第四部分主要分析研究区土地利用情况,从现状和动态变化两方面展开。第五部分分析了吉安市土地利用变化的驱动力,从定性和定量两方面进行。第六部分概括研究区土地利用的特点和问题,然后提出相应的措施第七部分是分析研究结论、不足及展望。
[Abstract]:The study of land use change has become a hot topic at present, and it has important practical significance to promote regional sustainable development. Ji'an City is located in the middle of Jiangxi Province, mainly in the mountainous area, and the economy is of medium level in the whole country. Due to the development of economy, the land use change of Ji'an City has changed greatly. The study of land use change in this area has certain guiding significance. This paper analyzes the present situation of land use and the dynamic changes of land use from 1996 to 2010, and then analyzes the driving force of land use change from qualitative and quantitative aspects. On the basis of this, some characteristics and existing problems of land use in this area are obtained. Finally, some suggestions and countermeasures are put forward, and the prospect is put forward. The study shows that there are various types of land use in Ji'an. The main type of land use is agricultural land, the cultivated land is second only to the woodland, the forest land is the main part in the land use mode of Ji'an city. The diversity index of land use in different counties (districts and cities) of Ji'an is quite different. (2) the quantity of agricultural land and construction land increased significantly, but the unused land decreased; H was 37.75 and the comprehensive index of utilization in 2010 was 228.18, indicating that the land use in Ji'an was in the developing period. The land use of Ji'an is still in the developing period, and the rate of land use change is 4.21; In recent years, the land use deviation degree of Ji'an city has declined slightly, indicating that the land use activities in this area have decreased the natural landscape intervention. 3) through the quantitative and qualitative analysis of driving force, the climate, topography and topography, hydrology can be obtained. Soil, population, economic and technological progress are the main reasons of land use change in this area. Among them, economic factors, population factors and technological progress are the main driving forces of socio-economic driving force. And the driving force has been strengthened year by year. 4) according to the existing problems of land use in this area, the corresponding countermeasures are put forward, and the prospect is put forward. The full text consists of seven parts: The first part is the preface. The second part is about the calculation methods. The third part mainly introduces the natural and social economic situation of the research area, as well as the data source and data processing method of this paper. The 4th part mainly analyzes the land use in the study area from the current situation and the dynamic change. The 5th part analyzes the driving force of land use change in Ji'an city from qualitative and quantitative aspects. Part 6th summarizes the characteristics and problems of land use in the study area, and then puts forward the corresponding measures The 7th part is the analysis research conclusion, the insufficiency and the prospect.
