在古代,中国历代劳动人民早已结合农业生产开展水土保持工作,创造了许多行之有效的水土保持措施。商代(公元前16至11世纪)人民已采用了防止坡地水土流失的区田法。此法颇似今天干旱地区农民应用的掏种法和坑田法。在西汉时代(公元前206至24年)我国山区已出现梯田雏形。战国魏文侯25年(公元前421年)曾引漳灌邺(今河南省安阳市)。陕西省耀县赵老峪的引洪水淤灌始于秦始皇时期。为了利用泥沙资源,黄土高原农民从明代起即开始打坝淤地,减
In ancient times, the working people of all ages in China had already carried out soil and water conservation work in combination with agricultural production and created many effective soil and water conservation measures. Shang Dynasty (16th to 11th century BC) People have adopted the Ward law to prevent soil erosion in the sloping fields. This method resembles the digging and pitting methods used by farmers in arid areas today. In the Western Han Dynasty (206-24 BC), the prototype of terraced fields appeared in the mountains of our country. Wei Wenhou of the Warring States Period 25 years (421 BC) had cited Zhang Irrigation (now Anyang City, Henan Province).
