【摘要】 成都西郊是目前成都市城市发展的主要方向，其特殊的区位环境决定了该区土地利用具有变化快、变化类型复杂及空间格局多变的特点。尽管四川省遥感中心已于2000年对四川省的土地利用进行了小比例尺遥感调查和分析，但针对本区的土地利用研究尚属空白。基于此，笔者收集了该区土地利用的有关资料，对本区的土地利用动态变化进行分析研究，以期成都市土地管理有关部门能从中了解该区土地利用的变化情况。 本文利用1988、1992和1998年的TM原始数据，经处理分析后，通过解译，得到三个时期的土地利用专题数据。在此基础上，应用分类结果比较法，在GIS各种空间分析功能(几何量算、统计分析、叠加分析及缓冲区分析)的支持下，对该区土地利用变化进行了如下分析：土地利用综合分析、城市化进程分析、耕地转化率分析、土地利用变化因素分析及土地的可持续利用分析。结果表明：该区土地利用变化主要表现为耕地大量减少，斑块破碎化；交通用地沿二环线呈放射状向四周扩展；城镇用地沿交通干线向西南方向扩张迅速，用地趋于集中；农村居民点和工矿业用地增加，用地趋于分散；其它用地变化较慢。这一用地变化的主导因素是城镇用地扩展快、人口增长迅速、外资的大量投入及以房地产为主的第三产业的快速发展。鉴于该区土地利用的变化情况，笔者认为该区应该在切实保护耕地的基础上，走土地可持续利用道路。 通过上述的土地利用变化分析，笔者对本区的土地利用历史变化过程进行了模拟，并预测其未来的土地利用空间结构模式。更多还原

【Abstract】 Western-suburb is the major expanding-direction of Chengtu urban.Because of the special regional-environment,its land-use has the characteristics as follows: change quickly,the changed-classification is complex and its spacial structure is uncertain. Although Szechwan central organization of Remote sensing has made some small-scaleresearch and analyzing work for Szechwan land-use based on RS in 2000,the research of land-use for this area still be vacant.So,on the basis of some collection of land-use evidences,the author made some research work of land-use dynamic change for this area,and expected that the land-administration of Chengtu can find out some useful information from them.Based on the original data of TM in 1988,1992 and 1998,then after some processing and analysis,the author have the thematic data of land-use by interpretation.On the basis of them,the author made the analysis of land-use for this area based on the spacial analysis of GIS and the method of comparison between result of land-use classification as follows:The method of aggregating analysis,the analysis of urbanization,the analysis of the transformation rate of cultivated land,the analysis of the driving force of land-use change and the sustainable use of land.The conclusions may be demonstrated below:The cultivated land decreases with the patchs fragment;Road spreads radialy surround second-ring road;The urban land expands quickly toward southwest along the major roads and be concentrative.Rural land and industry increse rapidly with dispersing;0thers change slowly.The major driving forces of land-use change in this area are the rapid expansion of urban and rapid growth of population,foreign investment and the development of tertiary industry which was based upon the real estate.According the trendency of land-use change,the author consider that we must insist on the way ofthe sustainable use of land based on protecting the cultivated land.According to the analysis of the land-use change,the author made simulation for the historical land-use change and forecasted the future spacial structure of land-use.更多还原
