摘　　要：以黑龙江省13个地级市为研究区,从生产、生活和生境3个方面构建了评价指标体系,应用突变级数法对研究区2003—2012年耕地利用生态效益的时空变化进行了分析.结果表明:(1)10年间,研究区耕地利用生态效益可分为4个变化时期,即2003—2004年的下降期,2004—2005年的上升期,2005—2007年的二次下降期,2007—2012年的缓慢上升期,耕地利用生态效益水平呈现波动发展的变化趋势.(2)2003—2008年,高效区、较高效区、较低效区的城市数量变化依次表现为减少、增加、保持不变;2008—2011年,高效区、较高效区、较低效区的城市数量变化依次表现为增加、减少、保持不变.(3)2003—2008年,高效区分布由东部、西北部向中部、东南部延伸;较高效区分布由南部、中部向东西部边沿延伸;较低效区分布由北部、东南部边沿向西部边沿延伸;2008—2011年,高效区分布由中部、东南部向中部四周延伸;较高效区分布由南部、东西部边沿向东南部变化;较低效区分布由西部边沿向南部、北部边沿变化.Cultivated land that uses eco-benefit evaluation for reasonable development,utilization and protection of cultivated land resources is of important guiding significance.This paper selects 13 District Cities（districts）in Heilongjiang Province as the study area.From the aspects of production,life and habitat evaluation index system and using catastrophe progression method,analysis the cultivated land use spatial and temporal variations of ecological benefits according to the study area in2003—2012.The research shows that：（1）In ten years,the study area of cultivated land that uses ecological benefits can be divided into four phases,It declined from the year of 2003 to 2004.It rised from the year 2004 to 2005.It declined the second time from 2005 to 2007amd rised slowly from 2007 to 2012.The cultivated land useage in the development of ecological suffered some fluctuations.（2）From 2003 to 2008,the number of high efficiency,more efficient,and more inefficient zone of cities respectively reduced,increased,and remained unchangeable.From 2008 to 2011,the number of high efficiency,more efficient,and more inefficient zone of cities respectively increased,reduced and remained unchangeable.（3）From 2003 to 2008,high efficient area stretched from east and northwest to central and southeast.More efficient area stretches from southern and central to the east and west edge.The inefficient zone stretches from north and southeast edge to the west.From 2008 to 2011,high efficient area that distributed in central and southeast areas spread to central China.More efficient area distributed from the southeast and west edge to the southeast.The inefficient zone changed from the western border to the southern and northern edge.
