【摘要】 <正> 太阳总辐射是地球表面最重要的能源。了解太阳总辐射的变化,对于研究气候的形成、探讨自然地理规律都具有重要意义。关于太阳总辐射的问题,有不少学者作过计算和研究。本文利用广东省1958—1975年的观测资料,就太阳总辐射的时空变化作初步的分析研究,以探讨其变化规律,以及总辐射与生产潜力的关系。更多还原

【Abstract】 Based on observational data of the total solar radiation in Guangdong (1958-1975), the total solar radiation changes of time and space and relation between total solar radiation and latent production forces are analysed. Guangdong is rich in total solar radiation. Owing to situating in low latitude,it provides a favourable condition for agriculture production. From the point of view of the effective using coefficient of the total solar radiation, the effective using coefficient of 2% is an index which has been reached nowadays (1000 jin of grain yield per mu), of 5% is an index which is possible of realization (3000 jin grain yield per mu), of 10% is a theorefic index which we wish to reach through our labour (5000-6000 jin of grain yield per mu).更多还原
