摘要:
利用户县1971-2000年逐年年平均日照时数、年平均气温、年平均降水量、年平均蒸发量资料，计算分析了户县的光合、光温、光温水生产潜力并提出了提高气候生产潜力的措施。结果表明：（1）户县在这30 a的时间里光合、光温生产潜力总体呈减小趋势，而光温水生产潜力总体趋势略升；（2）光合生产潜力7月最高，3-10月占年光合生产潜力的79.1%，是农作物生产的最重要时期；（3）户县历年各月光温水生产潜力等值线变化剧烈，农作物整个生育期中水因子制约作用超过了温度因子；（4）冬半年使用温室技术、夏半年增强作物水资源供给是户县气候生产潜力提高的有效措施。
Abstract:
The photosynthetic productive potential, light-temperature potential productivity and light-temperature-water potential productivity were calculated and analyzed by using the data of annual average sunshine hours, temperature, precipitation and evaporation from 1971 to 2000 in Hu County of Shaanxi Province. The results showed that:(1)The photosynthetic productive potential, light-temperature potential productivity, which showed a decreasing tendency and the light-temperature-water potential productivity, which showed an increasing trend with in 30 years; (2) The photosynthetic productive potential, maximum appeared in July, from March to October, it is an important period in the crop production.(3)The contour line of monthly mean light-temperature productive potential change greatly in Hu County, the water factors were the more controllable than temperature. (4) Using greenhouse technology in winter and supplying water resources in summer are effective measures of improving climatic potential productivity in Hu County of Shaanxi Province.
