| 摘 要： | 分析吉林省东部山区1978～1998年耕地数量的动态变化趋势和20世纪80年代中期(1986年为例)至90年代中期(以1996年为例)的土地利用类型转化，使用相关分析和层次分析法(AHP)对引起东部山区耕地数量和质量变化的自然方面、社会方面以及经济方面各因素进行分析，指出东部山区耕地变化的主要驱动力因子是人口因素、农业投入水平、市场导向和居民消费水平；新的发展形势下，耕地的压力仍然存在。该区应在保障粮食供给的情况下调整农业内部结构，发挥森林资源和野生动植物资源的优势，大力发展森林种植和养殖，同时积极发展森林旅游，缓解耕地压力，促进社会经济的持续发展。

| Abstract: | Land-use /cover change(LUCC) study has been an important subject, since it was put forward. Its theoretical analysis has converted from pure natural analysis to the combination with natural and socio-economical analysis, from macroscopic global analysis to small regional analysis, from multiple type analysis for land use to single type .One of the dimensions of the studies is to study the human driving forces, which cause the changes. Cultivated land is one of the main type of land-use, and it is closely, correlative to population, spatial distribution of agricultural produce and natural factors such as soil, air temperature, topograghy and water condition. Cultivated land is an important basis source for a region's sustainable development and food security. With the development of economy, increase of population and expansion of city, cultivated land is faced with heavy pressure to raise and to hold more and more people on it. There are several cases studies of LUCC in China for cities such as Shanghai and Shenzhen, which are both the developed cities. What about mountainous area in middle-level developed province. The paper gives the quantitative changes and qualitative changes of cultivated land in eastern mountainous area of Jilin Province. Using correlation analysis and combining natural status, social status and economy status, we can get the causes of the dynamic change. With AHP, the conclusion is obtained that the decrease of the cultivated land in east mountainous area has close correlation with the increasing population, the level of agriculture skill, and economical policy. |
