摘要
世界上大部分红壤地区,由于受行星风系副热带高压控制,大都沦为沙漠;而我国南方红壤受太平洋季风的影响,具有热量丰富,雨量充沛,植被组成多,土地适种性广。但是,由于该地区地形复杂,降雨大而集中,盲目毁林,导致了严重的水土流失。近年来,尤其是大面积的低坡和缓坡地垦荒,更加剧了水土流失。目前,根据农村一家一户的承包所有制,在红壤坡地的不同利用方式中,应首先推广简单易行的费工少、见效快、效益高的等高耕种法,控制水土流失,保护自然,造福人类。
Controlled by subtropical high pressure of the planet wind system,most red soil regions in the world have become deserts, while red soil regions in the southern China, affected by the pacific monsoons, have plentiful sunshine, rainfall and vegetation, where the natural conditions are adaptable to various crops. But owing to the complicated topography, heavy and concentrated rainfalls and unchecked deforestation,there has been serious soil and water loss. In recent years, large areas of low and gentle slopes have been reclaimed for farming, fruit growing and forestation, thus aggravated the loss. At present, according to the household contract system in countryside, when different uses of the red soil slopes are made, first of all,the simple, easy, effective and beneficial contour farming method should be used to control soil and water loss and to protect the nature so as to bring benefit to mankind.
