| 摘 要： | 为了定量了解研究区土地利用类型转换关系及其变化强度与剧烈程度，笔者基于地学信息图谱分析，运用ERDAS8.5和ARC/INFO9.2软件，以马尔柯夫空间概率模型为基础，结合土地利用动态度模型及土地利用综合动态度模型，利用绥化市31年（1980-2010年）土地利用格局4期的空间数据（1980年、1995年、2000年、2010年）合成一系列土地利用格局变化图谱，通过图谱分析来了解绥化市的土地利用格局变化规律。结果表明：耕地大幅度增加，其净增面积346.4 km2，占研究区总面积超过13%，未利用地（滩地和沼泽地）面积急剧减少，净减少面积为440.9 km2，沼泽地完全消失。草地面积略有增加，增加面积12.1 km2，林地面积减少，减少面积为11.4 km2。城市建设用地净增加面积为29.7 km2。在过去的31年间，综合土地利用动态度急剧上升，土地利用格局发生剧烈变化，土地利用类型单一化明显，城市化进程加快，本研究区中部的滩地与沼泽地变化最为剧烈。

| Abstract: | In order to quantitatively examine the patterns of land use changes and the strength and intensity of changes, this research developed a geographic information TUPU probability. With the support of ERDAS8.5 and ARC/INFO9.2 degree model and an int of the land-use patterns egrated land use dynamic degree model, utilizing the spatial data and examined the changes of land-use pattern in analytic method and a Markov model of space software, combined with a land use dynamic the author explored a series of varying TUPU covering Suihua for 4 periods （1980, 1995, 2000 and 2010）, Suihua through the TUPU. The farmland had a net increase of 346.4 km2 （exceeding 13% of the total study area）, and most of farmland was converted from saline land, swamp land, forest land and grass land; unused land had a sharp reduction of 440.9 km2 and the swamp land had disappeared at the end of study period. The area of grass land had increased 12.1 km2. There had been a slight decrease in forest land, and the area of decrement was 11.4 km2. There had been a slight increase in construction land, and the area of increment was 29.7 km2. The results also indicated that significant changes had taken place on the land-use pattern in the study area during the past 31 years. The simplification of land use type became significant, the swamp land changed significantly in the centre section of study area. Urbanization and the integrated land use dynamic degree accelerated during the study period. |
