摘 要:耕地利用效益是衡量耕地生产能力和农业可持续发展的重要指标,它具有一定地域的时空分布特征。以黑龙江省东部垦区的宝泉岭、红兴隆、建三江、牡丹江4个农场群为研究区,选取18个具有代表性的指标,构建研究区的耕地利用效益评价指标体系,利用改进的功效系数法和协调度模型,定量计算研究区1999—2008年10年耕地利用经济效益、社会效益、生态效益及其三者的协调度和耕地利用综合效益值,同时运用ArcGIS手段,对1999—2008年研究区耕地利用综合效益特征进行空间分析。结果表明:1999—2008年,研究区耕地利用效益呈现出不稳定的波动状态,且耕地利用综合效益始终受经济效益、社会效益及生态效益三者之间协调度的影响。研究区的耕地利用效益呈现出东北部和中部高、西北部和南部低的明显区域差异性特征。Land use efficiency is a important indicator for measure the production capacity of cultivated land and sustainable agriculture. It has the certain features of spatial-temporal variance in area. This paper selects the farm clusters area-Baoquanling, area-Hongxinglong, area-Jiansanjiang, area-Mudanjiang as the study area in eastern of Heilongjiang province, and selects 18 representative indicators. Construct the index system of evaluation on comprehensive benefit for cultivated land in study area. Using the improved efficiency coefficient method and coordination model for quantitative calculation the economic, social and ecological benefits,their coordination and the comprehensive benefit of cultivated land use in study area in 1999-2008 years. At the same time, use ArcGIS for spatial analysis on the characteristics of the comprehensive benefit. The results show that the comprehensive benefit of cultivated land use is the unstable wave motion, and it is always impact by the coordination of economic, social and ecological benefits in 1999-2008 years. The differences in the apparent of the characteristics show that the utilization benefit of the cultivated land in northeastern and central of the study area is high, in north-west and south of the study area is low.
