摘　　要：为提高河北省山区土地资源利用水平,2007年3月在河北省37个山区县进行土壤和玉米采样,运用机制法的逐步订正模型分别对河北省坝上水资源生态保护区、燕山水资源生态保护区、冀西北水资源生态保护区、太行山水资源生态保护区的土地生产潜力进行了定量估算.研究结果表明,河北省山区粮食生产水平还很低,可挖掘的潜力还相当大,优化光热水肥的组合方式,是提高粮食产量的根本;水分条件是影响河北省山区农业生产潜力的最关键因素;土壤中氮、磷含量低,是山区玉米产量的另一限制因子.To improve the level of resource utilization mountain area in Hebei province,in March 2007 in 37 mountain counties of Hebei province,soil and corn samples are done,using the revised model of the progressive mechanism of France respectively,a quantitative estimation is carried out on potential of the land productive capacity in ecological protection of water resources in Hebei Bashang areas,water resources,Yanshan protected areas,ecological protection areas of water resources in northwestern Hebei province and Taihang Mountain area of ecological protection of water resources productive capacity.Result indicates that field grain level of production is very low,but the potential excavating is fairly pretty big.Fat combination of glossy hot water way is optimized to improve the grain yield foundation.
