| 中文摘要: |
| 应用黄土高原7省51个代表性气象站1961～2000年主要气象要素观测资料,采用EOF和其他数理统计方法研究了黄土高原气候与气候生产力对全球气候变化的响应,结果表明:中国黄土高原年和各季节的平均气温均呈明显的上升趋势,增温速度大于全国同期增温速度;年降水量和作物生长季节降水量均呈下降的趋势;气候生产力呈递减趋势;未来"暖湿型"气候对作物生产最有利,平均增产幅度为5.9%,而"冷湿型"气候对作物生产最不利,平均减产幅度为6.3%。 |
| 英文摘要: |
| The data collected by 51 meteorological stations distributing in seven provinces of the loess plateau and such statistic methods as EOF were used to study the Effects of the climate and climatic productivity in the loess plateau of China on global climate. The results showed that in the loess plateau, the annual and seasonal temperatures clearly tended to rise and the temperature- increasing rate was higher than that the national average in the same periods; both the annual rainfall and seasonal rainfall tended to decrease; the climatic productivity tended to decrease; the future warm-type climate was beneficial to crop production increasing with a yield-increasing rate of 5.9% but the cold-type climate was detrimental to crop production with a yield-decreasing rate of 6.3%. |
