摘要
毛乌素沙地是中国研究和治理的几大沙漠之一。这一地区拥有丰富的太阳能资源，年总辐射量约６，２８０ＭＪ·ｍ￣（－２），自然植被的总产量仅为６０ｋｇ／ｋｍ￣２，太阳能利用率大约占０．５％，因此，摸清植物与辐射因子之间的关系，对植物高产理论研究有非常重要的意义。由于近年来我国科学家在农业区划工作中对辐射因子已引起重视。但是，对其间接计算研究做得较多，实地测定工作开展的还不够。我们开展的沙地辐射因子的研究，不仅为沙地利用的进一步研究提供理论基础。
The Maowusu Samdy Land is one of a few desert areas in chinawhere can be explored and harnessed.The solar energy resource is rich in thedesert.Annual total radiation is about 6,280MJ·m￣(-2)①,but the output of naturalvegetation is only 60kg·km￣(-2)②. Utilization ratio of solar energy is around0.5%②.So that it would be significant for theoretical research of raising plantvield if the relationship between plants and radiation factors could be foundout. Chinese scientists have begun to pay more attention to radiation factorsbecause of the recent research on agricultural regionalization throughout chi-na.But their emphasis was indirect calculation rather than field investigation.The work we have done on the sands radiation factors can not only providesome theoretical bases for further study on utilization of the Sands but alsogive some new ideas to the research of the Sands,micro-climate.
