中文摘要	半城市化是在大城市周边，国内外资本在区域空间快速积聚和区域产业结构迅速调整，导致区域发生无规则的快速城市化过程。本文选择小尺度半城市化区域为研究对象，评价区域城市化综合水平，研究区域的土地利用变化及驱动机理，分析区域景观变化。旨在探询半城市化地区土地利用及景观变化特点，揭示半城市化地区土地利用及景观变化影响机理。全文共分五章：第一章，文献研究综述。总结国内外城市化发展步伐及城市化和半城市化研究进展，并概括国内外土地利用及景观变化研究现状及主要研究模型与方法。第二章本文选题背景及方法。主要介绍选题的背景条件，阐述选题的目的，研究的意义、方法和思路。第三章，成都市城市化水平综合测度研究。采用层次分析法，建立城市化综合水平测度的指标体系，在专家并评分的基础上计算成都市各区、市、县（城市建城区除外）的城市化综合水平。发现成都市城市化综合水平较高，但区域内部的差异较大，大致可以分为中心城区、内部半城市化区、外部半城市化区、农业区。第四章，半城市化地区土地利用及景观变化研究。这是本文研究的重点，共分三节：第一节，总结龙泉驿区的自然条件及社会经济条件。第二节，分析半城市化地区的土地利用变化，发现在1996-2004年期间，研究区土地利用程度持续提高；园地、居民点及工矿用地呈现较大增幅；农业用地内部调整与非农化调整特征明显。分析研究区土地利用变化驱动过程，发现果业与乡村旅游业发展是研究区农业结构调整的主题，也是导致土地利用结构变化的重要驱动力；源于外来资本的房地产投资、工业项目投资是另一个主要驱动力。第三节利用GIS技术和景观生态学方法，研究区域的景观格局变化特征。研究过程中主要以1996年和2004年土地利用景观格局数据库为基础，采用景观类型面积指数、景观破碎度、景观分离度、景观多样性指数、景观优势度、景观均匀度、景观形状指数分析区域土地利用景观格局变化特点。发现1996-2004八年间，研究区景观变化较大，各景观类型面积比例差异增大，土地利用结构混杂，景观破碎化程度变大，景观形状不规则化程度加剧。第五章，结论和展望。总结本文研究的主要结论，提出城市化进程中推动区域土地资源的持续利用的建议。期待本文的研究成果能指导相关行业的工作，并为更科学地制定区域土地利用规划和区域土地利用政策提高决策依据。在未来的研究中期望完成多区域的综合比较研究，实现定量化地判断区域经济及城市化进程的问题，并总结和完善城市发展规律。
英文摘要	The peri-urbanization is the process of irregular rapid urbanization around megapolis, due to the rapid accumulation of native and overseas capitals and the quick adjustment of regional industrial structure. In this paper, we choose the little-scale section of peri-urbanizaiton as our research object, to evaluate the comprehensive level of urbanization, to study the changes of land utilization and its driving factors, and to analyze the changes of landscape. All the endeavors is to exploring the characteristics of the changes of land utilization and landscape in peri-urbanization areas, and making out the influencing mechanism of the changes of land utilization and landscape in peri-urbanization areas.This dissertation includes 5 chapters, as following: Chapter 1, the summarization of researches related to our study. We summarize the process of domestic and foreign urbanization, and the domestic and foreign study of urbanization and peri-urbanizaiton, then generalizes the technique and model in the study of the change of land use and landscape. Chapter 2, the contexts and methods in this dissertation, mainly introduce the backgrounds, the purposes, and significances of our research. Chapter 3, the level of urbanization in ChengDu, uses the AHP to set up comprehensive index in according to the level of urbanization, and then calculates comprehensive level of urbanization including county and urban region in ChengDu based on experts’ scores. We discover that the level of urbanization is very high in ChengDu, and its inner diversities are also obvious. We classify it to four levels by the large, the first level is urban core, the second level is per- urbanization, the third level is outer peri-urbanization, and the forth level is rural Chapter 4, the core of our research, includes three sections. The first section introduces the natural and social status in LongQuanYi district; The second section analyzes the change of land use dated from 1996 to 2004 in peri-urbanization area, and find out that the degrees of land use are continuously increasing; Garden plot, residential area and industry plot even have a bigger increase; the inner adjustment of agricultural and non- agricultural land are very obvious. And what’s more, when analyze the driving powers of land use change, we find that the planting of fruit and tourism in country areas, are the main theme for the adjustment of agricultural structure and leading drive for the change of land use structure; the investment of external capital to real estate and industrial project are another driving power. The third section studies the changes of landscape structure by the technique of GIS and the method of landscape-ecology. Based on the data-base of land use in 1996 and 2004, we use the landscape acreage index, landscape fragmentation index, landscape apartness index, landscape diversity index, landscape dominance index, landscape evenness index and landscape shape index to analyze the characteristics of the changes of landscape. We find that landscape structure has intensively changed; the diversities of acreage ratio of various landscapes and the extent of landscape fragmentation have augmented a lot, the structures of land utilization get more complex, the extent of abnormity of landscape shape has enhanced during 1996 to 2004. Chapter 5, conclusion and our prospect, summarizes the main conclusion in this study, then gives advice which can promote sustainable utilization of regional land in the process of urbanization. We expect that our study would give some advice to relative departments, and make reasonable policy and layout of regional land utilization. We also expect to study more different regions as contrasts, in order to develop quantitative index to determine the progress of urbanization and regional development, finally summarize and consummate the law of peri-urbanization.
