| 摘 要： | 研究四川盆地西缘中低山地区耕地的时空结构变化,结果表明,旱地数量在500～1200m范围内随海拔高度的上升而增加,但1200m以上数量锐减,水田数量总体而言随海拔高度上升而减少;十年来的经济发展和社会政策等综合的人为因素使耕地数量随时间变化而较大程度减少。

| Abstract: | By studying cultivating land's space-time dynamic change of middling and low land in the west of Sichuan basin, the result show that the dry land's quantity increases with the ascend of altitude between 500 meters and 1200 meters and paddy field's quantity reduces with the ascend of altitude. Cultivating land's quantity reduces in high degree with the change of time due to some factitious factors such as economic development and society policy. |
