黄土高原的气候生态环境、气候变化与农业气候生产潜力

Climatic ecological environment, climate change and agricultural productivity in Loess Plateau

分析了黄土高原的气候生态环境特征,计算了近40a黄土高原的光温和气候生产潜力,并根据未来气候变化的可能情景,计算和分析了未来50a该地区光温和气候生产潜力的可能变化。结果表明,在未来50a,除东南部外,其它各区总的来说无论是小麦的光温生产潜力还是气候生产潜力均有所增加,而且光温生产潜力增加的幅度大于气候生产潜力的增加幅度。

This paper analyses the feature of climatic ecological environment in Loess Plateau, and calculates the potential productivity of radiation and temperature and the potential productivity of radiation, temperature and precipitation during recent 40 years and next 50 years. The results show that apart from the southeast part, either the potential productivity of radiation and temperature or the potential productivity of radiation, temperature and precipitation will tend to increase in next 50 years, and the increase range of the former potential productivity is larger than the latter.
