本文在分析哀牢山北段光资源随海拔和坡向变化特征时发现,与迎风西南坡比较,背风东北坡海拔1000—1900米处有一较强的年日照和太阳总幅射增加的焚风效应带,尤以海拔1500—1600米最明显,这有利于农业生产,但在>1900米处则相对较低。最后,给出日照与雨量的指数关系。 In this paper, we analyzed the characteristics of light resources in northern Ailao Mountain with altitude and aspect change. Compared with the southwest of the upwind wind, there is a strong annual sunshine and increased total solar radiation at the altitude of 1000-1900 meters on the northeast of the leeward The effect zone, most notably at 1500-1600 m above sea level, favors agricultural production but is relatively low at> 1900 m. Finally, an exponential relationship between sunshine and rainfall is given.
