摘　　要：以吉林西部为例,基于遥感与GIS技术,应用转移矩阵分析用地数量格局变化,应用景观指数分析用地空间格局变化。结果表明,2000-2007年吉林西部耕地面积增加,林、草地面积减少,用地格局单一化发展;湿地退化,水域萎缩,水资源减少加剧了盐碱化发展;盐碱地数量得到控制,盐碱化程度加重,治理难度增大。结合统计数据分析,吉林西部用地格局变化受自然因素的胁迫,人为因素的干扰加速了生态环境恶化,调整土地利用结构、因地制宜配置土地资源是改善区域生态环境的惟一途径。Based on the RS and GIS technologies,the quantity pattern changes and spatial pattern changes of land use in western Jilin were analyzed using transfer matrix and landscape indexs respectively.The results showed that from 2000 to 2007,the agricultural land in western Jilin increased,while the forest and grass land decreased,the land use pattern showed a single development.The wetland degenerating,lake waters atrophying,and water resource decreasing aggravated the salinization development.Although the quantity of saline-alkali soil was controlled,the degree of salinization became serious,thus the improving was difficult.The changes of land use in western Jilin province were stressed by natural factors and the disturbances of human factors made a quick environmental degeneration.So the adjustment of land use structure and being adapt to land resources was the only way to improve the regional entironment.
