我国是一个水土流失面积较大、危害较重的国家。目前,水土流失面积达150万公里~2,折合22.5亿亩,超过了耕地面积,约占国土的六分之一。北起黑龙江,南至海南岛,从西北的黄土高原,到东部的沿海之滨,水土流失遍及全国各地,严重威胁着我国的农业生产。解放三十年来,党和政府十分重视水土保持工作,共治理水土流失40万公里~2,取得了很大成绩。但由于片面强调“以粮为纲”,到处毁林毁革开荒,再加上林彪、“四人帮”的干扰破坏,治理速度赶不上破坏,水土流失面积不但没有减少,反而
Our country is a country with a large area of soil and water loss and a heavy toll. At present, the area of soil erosion reaches 1.5 million km2, equivalent to 2.25 billion mu, exceeding the cultivated area, accounting for about one sixth of the land. From Heilongjiang in the north and Hainan Island in the south, from the northwestern plateau to the coast of the east, water and soil erosion spread all over the country, which seriously threatens the agricultural production in our country. Since the liberation for 30 years, the party and the government have attached great importance to soil and water conservation and have handled a total of 400,000 km2 of soil and water loss. Great achievements have been made. However, due to one-sided emphasis on “food as the key link”, deforestation and land reclamation everywhere, combined with the interference and destruction by Lin Biao and the “gang of four” and the failure to keep pace with the control, the area of water and soil erosion has not diminished. Instead,
