【摘要】 利用陕西各气象台站１９６１年至１９９０年气象观测资料和１９９２年陕西省农业生产状况调查报表的资料，应用布达哥夫斯基连乘原理，引用了灌溉因子对陕西省陕北黄土高原沟壑区、渭北旱塬区和关中平原区三个气候区的光合生产潜力、光温生产潜力、气候生产潜力和综合气候生产潜力进行了估算，并将综合生产潜力计算结果通过小网格方法绘制成小网格分布图，分析了各气候区综合气候生产潜力的分布特征，以为上述地区的农业及多种经营的潜力开发提供气候依据。更多还原

【Abstract】 By using irrigation factors, potential productivity of photosynthesis, photo tempeature, climate and comprehensive climate in arid and semiarid areas of three different geographical positions in Shaanxi Provinec was estimated on the basis of meteorological date collected from 1961￣1990 and agricultural production date obtained in 1992. At the same time, distribution feature of comprehensive climate potential productivity was analyzed in application of fine grid metod. The results of the estimation and analysis may be used as reference for tapping local potentiality in agricultural development in these three areas.更多还原
