摘  要:
利用2000-2013年成都市下辖各县区耕地面积和农业劳动力资源,以劳耕弹性系数为基础,采用GIS技术分析其耕地面积和劳动力变化的时空耦合特性。研究表明,成都市68%的地区劳耕弹性系数已表现出衰退型迹象,人地关系日益紧张,其耕地重心和农业劳动力重心在移动方向上具有相似性。

摘  要:
Using the counties arable land and agricultural labor force resources,from 2000 to 2013,on the basis of Labor-Farmland Elastic Coefficient(LFEC), using GIS technology to analyze its arable land and labor changes in time and space coupling characteristics. Research showed that 68% of the region of Chengdu Labor-Farmland Elastic Coefficient had been shown to decline model type,and the corresponding relation between people and land were increasingly vulnerable,gravity center of farmland and agricultural labor had the similarity in the direction of movement.
