突泉县太和乡和丰村有耕地面积9044亩,其中大于5°的坡耕地就有6300多亩。过去由于不少坡耕地顺山垅耕,水土流失非常严重,每年暴雨过后,顺垅形成许多平行侵蚀沟,每亩年冲刷量达2.3～5.0吨,粮食产量低而不稳。为了防治坡地水土流失,该村1972年开始修水平梯田,但因人少地多,工程量大,到1982年仅修梯田375亩,平均每年75亩,如此进度,要把全村6300亩坡耕地全治完,至少需要80年。1983年初,该村在县水保站的帮助下,进行了综合治理规划,在坡耕地治理上,首先把全部坡耕地变成等高 Tuquan County Taihe Township and Feng Village has 9044 acres of arable land, of which more than 5 ° of slope farmland has 6,300 acres. In the past, due to a lot of slopes of cultivated land, farming and soil erosion were very serious. After heavy rains each year, many parallel erosion ditches were formed along the river. The erosion volume per acre reached 2.3-5.0 tons and the grain yield was low and unstable. In order to prevent soil erosion, the village began to repair the terraced fields in 1972. However, due to the small number of people and large quantities of works, only 375 mu of terraces were to be repaired in 1982, an average of 75 mu per year. With this progress, the whole village has 6300 mu of slope All the arable land, at least 80 years. In early 1983, the village under the help of the County Soil and Water Conservation Station, conducted a comprehensive management plan, slope farmland management, first of all the sloping farmland into contour
