Effect of Terrain Factors on Land Use Change in Typical Black Soil Region

GE Cui-ping1,2,ZHAO-Jun1,YIN-Sheng1,3,ZHAO Kuangshi4 (1.Northeast Institute of Geography and Agricultural Ecology,Chinese Academy of Sciences,Heilongjiang Key Laboratory of Blacksoil Ecology,Harbin 150081,China;2.Graduate University of Chinese Academy of Sciences,Beijing 100049,China;3.College of Resources and Environment,Northeast Agricultural University,Harbin 150030,China;4.University of Information Technology,Chengdu 610225,China)  
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 9 348.75hm2,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.
