摘  要:
经详细分析近 3a上海地区的气象资料 ,发现 2 0 0 3年上海地区的气候与往年相比 ,更有利于秋色叶的形成 ,其主要原因是 :较大的光照强度有利于光合作用及色素的形成 ;较大的昼夜温差有利于植物体内糖分的积累及花青素的形成 ;较高的空气相对湿度有利于秋色叶形成。影响秋色叶变化的内部因素主要是光合产物的变化 ,外部因素为光照、气温、水分等。

摘  要:
By analyzing the meteorological data in Shanghai in the past three years, it was found that the climate condition in 2003 was more beneficial to form autumn-color leaf compared with the climates in the other two years. Higher illumination intensity, larger difference in diurnal and nocturnal temperatures and higher air moisture were advantageous to photosynthesis, the forms of pigment and anthocyanin and the accumulation of sugar. The intrinsic factor influencing the autumn-color leaf is the change of photosynthetic production, and the extrinsic factors are illumination, temperature and moisture.
