摘要
研究目的:探讨农牧交错区近百年来的土地利用变化驱动机制。研究方法:利用TM、MSS遥感影像数据、地形图数据以及社会经济统计等数据,在遥感和GIS技术支持下对案例区百年来的土地利用/覆被变化原因进行分析。研究结果:研究区农林牧渔等多种经营方式决定了其土地利用的空间分布及其变化;研究区在历史上屡受嫩江洪水影响,致使很多村庄迁移,在区域空间上引起土地利用变化;蒙古族生产方式主要是游牧,后汉族将农业生产方式带到该地区,对土地开发影响非常大。研究区在1960年代进行了三次大量内迁移民,也加速了土地的开发。研究结论:研究区近百年来的土地利用变化受自然灾害、人口增长、经济发展、战争、政策、体制等的影响比较大。
The purpose of the paper is to analyze the mechanism of LUCC and its driving forees since the 1930s. The causes of LUCC in the case study area was analyzed by making use of the data of TM, MSS images, terrain and social economic statistical data, etc. The results indicated that various management ways determined the spatial distribution and change of land use, such as agriculture, forestry, pasturage and fishery. The study area was affected by flood from Nenjiang River several times in history, many villages migrated and the spatial paltern of land use changed as a result. The inhabitants in Mongolia were mainly nomad in tradition. However, the land development in this area was deeply influenced after the immigrants from Han ethnical group brought in their agricuhural production pattern. Especially in the 1960s＇, there were three times of large-scale immigration that accelerated the land development. In conclusion, the land use/cover change was deeply affected by natural disasters, population and economic growth, wars, policies and political system in the study area.
