对河南省济源市1971-2000年的气温、降水量、日照时间及几个重要的界限温度的活动积温、等作为主要研究对象进行统计分析,并简要分析其对农业的影响,结果表明:济源市气候趋向暖干化,特别是90年代升温最为明显;降水为减少趋势,从80年代开始就比较明显;日照时间从80年代开始迅速减少;各重要界限温度的活动积温随年代增加。此趋势对农业生产有利有弊,将会影响到农业生产的布局和结构。
Based on the statistic analysis of the temperature, precipitation, sunshine hours and the accumulated temperature of several important boundary temperature during 1971-2000 in Jiyuan City, Henan Province, the main research object is statistical analysis, and its impact on agriculture is briefly analyzed. The results show that Jiyuan The climate of the city tends to be warm and dry, especially the warming in the 90s is the most obvious. Precipitation is the decreasing trend, which has been obvious since the 1980s; the sunshine duration decreased rapidly from the 1980s; the accumulated temperature of activities at various critical temperatures increased with the age. This trend has both advantages and disadvantages to agricultural production and will affect the layout and structure of agricultural production.
