摘    要:以海伦市为例,以1986、2000年两时段土地利用数据为基础,运用马尔可夫模型分析土地利用变化,并在ARC/INFO支持下,从坡度、坡向两个方面分析土地利用变化规律。分析表明:耕地、林地、牧草地及沼泽地之间的转化明显,耕地的增加主要来自于林地、牧草地及沼泽地的减少,其中丘陵旱田增幅最大为218%;坡度和坡向在很大程度上影响着土地利用变化的方向,耕地分布的坡度增大,灌木林地、疏林地在水土流失发生地带(1°-8°)明显减少。林地、牧草地等土地利用类型破坏严重,向着农田化方向发展趋势明显,应加强地区的生态环境建设。图2,表3,参11。

关 键 词:典型黑土  坡度  坡向  土地利用变化

Abstract:In a case study in Hailun city, Markov model was used to analyse land use change based on land use data of 1986 and 2000.The pattern of land use change was analyzed from slope and aspect using ARC/INFO. The results showed that the transform of farmland, forests, grassland and wetlands was obvious. The area of farmland increase was 9 348.75hm^2, most of which was from the decrease of forests, grassland and wetlands. Hilly farmland had the biggest increase with 218 percent. Slope and aspect took an important effects on land use change. The distribution of farmland was on higher slope, while forests had a obvious decrease where soil and water erosion tended to happen with slope 1° - 8°. Forests and grassland were damaged badly with a trend to be used as farmland, so more attention should be given to the ecology environment.
Keywords:typical black soil  slope  aspect  land use change
