摘要
本文通过对江淮丘陵、皖西山区和淮北平原的不同时期的森林杠益率与降水量的分析 ,结果表明随森林覆盖率的增加 ,年平均降水量呈增加趋势 ,森林覆盖率的增加 ,有利于调节降水 ,减少旱涝灾害。森林覆盖率对过程性降水影响小 。
Inventories were made in the hillock area along Yangtze and Huai rivers, the mountainous area in western Anhui, and the plains area north of Huai River, regarding the forest cover and precipitation at various stages. Analysis indicated a rise of the mean annual rainfall with the increase of the forest cover. It is further indicated that forest cover has a greater effect on local precipitation than on storm precipitation.
