- 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 of the sustainable use of land based on protecting the cultivated land
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。 - Supported by remote sensing and cis , through image processing , information extracting and based on mathematic models of plural information , in this paper , some favorable gold areas in mian - ning and yan - yuan area have been predicted , and it achieved the following results : ( l ) through remote sensing image digital processing , we made high accuracy remote sensing images and image interpretion maps . constructed a geodatabase of mianning - yanyuan - xichang area , including basic data ( district . drainage , etc . ) and thematic data ( rupture , stratum , magmatic rock , etc . ) . this will provide scientific evidences for work of this area in the future
并取得了以下成果： ( 1 )通过遥感图像数字处理，制作完成了实验区的高精度遥感影像地图及遥感解译图，建立了冕宁-盐源-西昌一带空间数据库，包括基础数据(行政区、地名、水系等)和专题数据(断裂、地层、地质体等) ，为该区进一步工作提供了科学依据； ( 2 )根据各个多元信息成矿预测模型的优缺点，分析了不同预测模型的适用条件和范围，确定了研究区采用的数学模型。
