摘要: 在全面分析国内外有关气候变化著述的基础上,本文指出,就气候变化的自然因子而论,未来气温有可能下降。从人为因子而言,温度有可能上升。当升温肘,北美及地中海西北部等地可能趋于干旱,而欧亚、南美及澳大利亚等地不可能出现干旱。但升温引起的海面上升是全球性的,对我国沿海地区将产生巨大影响。

Abstract: The analysis of climatic change and the effect of atmospheric CO2 concentration shows that climate will tend to become cool in the future according to natural factor affecting climate,but it will tend to become warm according to man’s factor.When climate becomes warm it will get arid in the North America and the Northwest Mediterranean,while in Eurasia,South America and Australia it will get humid.The rise of sea-level produced by warming will have great effect on the area along the coast of China,as well as on all coasts of the world.If natural resources,especially land and wood resources,are reasonably used,most of desertification in east and northwest China will develop toward the ecological environment with high efficiency.
