我国远古治水,采用疏导策略,使泛滥洪流注入江河,东流入海。古有“禹疏九河”之说。当时,存在着原始林草、天然湖泊,起到了拦沙滞洪的作用。以后由于农牧业的发展,灌溉工程也随之发展起来。与此同时,因人口的增长,扩大了对耕地、草场的需要,无计划的垦耕,破坏了天然植被。黄河流域的黄土区是我国农、牧业的发源地,也是我国人口密集地区,植被破坏最早,更以黄土质地松散, In ancient China, we used water diversion strategies to divert flooding floods into rivers and east into the sea. The ancient “Yu Shu nine river” said. At that time, there were primitive forests and grasslands and natural lakes, playing the role of blocking floods and detention. Later, due to the development of agriculture and animal husbandry, irrigation projects also developed. At the same time, due to population growth, the demand for arable land and grassland has been expanded, unplanned reclamation and natural vegetation have been destroyed. The loess region of the Yellow River Basin is the birthplace of agriculture and animal husbandry in China. It is also a densely populated area in China with the earliest vegetation damage and loose loess texture.
