【摘要】 利用逐步订正等方法,结合本地区自然、社会和经济统计资料,对青海湖地区耕地资源不同层次作物生产潜力、潜力总量进行了估算,分析了青海湖地区影响作物生产潜力的限制因子。结果发现,热量和水分因子是青海湖地区影响作物生产潜力的主要因子,现有耕地的最大粮油生产潜力总量为12165165kg。在此基础上计算了各层次的耕地生产潜力利用率,对影响该地区耕地生产潜力的因子进行分析。最后提出了青海湖地区实现耕地生产潜力可持续利用的对策。更多还原

【Abstract】 With the gradual revison method,combined with the natural,social and economical statistical data,the article estimated infield resources of Qinghai Lake area of the crop production potential and the total potential of different leaves,and analyzed the limiting factors that affect the crop production potential in Qinghai Lake area.Results show heat and water factors are the primary factors.The most crop production potential of present infield is 12 165 165 kg.Based on it,the using rate of production potential of different infield was calculated and the field production potential fators of this area were analyzed.Finally countermeasures to realize sustainable use of the infield productive potential were put forward.更多还原
