中文摘要在本区(102°35′—109°15′E,28°50′—33°10′N,土地面积15.5万平方公里)土地利用现状调查中,用影像判读标志和地理景观综合分析判读,确定地理要素(纬度、地貌、海拔、坡度、坡向)和人类开发活动对土地利用类型的影响,掌握各种地类的分布规律和开发利用特征。据此,对 9个一级地类和 18个二级地类编制成1:20万土地利用现状图。经野外验证,判读准确率91%。 
英文摘要This region is situated in 102°35’-109°15’E,28°50’-33°10’N. The land area is 155,000 km2.Tn order to survey the land-use conditions in this region,the effects of geographic elements on the land-use types are determined, and the distribution law, development and utilization characters of different land-use types are understood by image interpretation mark and synthetic anal- ysis of geographic landscape.The differences of latitude will cause the horizontal differentiation on land-use types. The differences of landform and altitude will cause the vertical differentiation on land-use types. The slope and exposure have an effect on light, heat, water and soil conditions of any land- use type. The different levels of exploitative activities of human will make both regional distributed scales and structures of any land-use type to have differences.According to this,the current map of land-use in the scale of 1:200,000 is drawn to 9 Ⅰ land-use types and 18 Ⅱ land-use types. The standard of every land-use type which can be shown on the map is 4mm2. The delineated displacement of any land-use type boundary may be ≤0. 3mm (to obvious ground object) or≤1.0mm(to unclear ground object). The accuracy ratio of interpretation is 91%.
