摘　　要：用土地压力定量评估方法,以承德市八个县区1999～2005年统计数据为基础,评估各县区粮食生产压力和经济发展压力,并将其与实际土地生产力和经济发展实力进行了比较。结果表明:土地压力在空间上具有非均衡性,但相对于土地生产力的相对土地压力则存在空间均衡化的趋势。1999～2005年,区域25%的县粮食生产能力能够支撑粮食生产压力,各县区土地经济产出都不能够支撑其经济发展压力。如果土地压力不能得到有效缓解,粮食生产、经济发展与生态保护之间会存在明显冲突。劳动力转移、发展经济林果和特色产业等是缓解上述压力的主要途径。By using the land pressure quantitative assessment method,and the eight counties statistical data from 1999～2005,we evaluated each county＇s grain production pressures and economic development pressure and compared it with the actual strength of land productivity and economic development.The result showed that the land pressure was unbalanced in space,but relative to the unbalance of land productivity,there was a trend of equalization of land pressure in space.From 1999 to 2005,25% of the county＇s grain production capacity could support grain production pressure,but each county＇s economic output could not support its pressure for economic development.If the land pressure could not be effectively relieved,there would be an obvious conflict between grain production and economic development and ecological protection.Labor transfer,development of the forest and fruit growing and characteristic industry etc are the main ways to alleviate the pressure.
