海河(包括滦河)流域山区面积18.97万平方公里,占流域总面积的59.5％。全流域共分8个河系,呈扇形分布,各河系上游山区水土流失都很严重,据统计,流失面积约12万平方公里,占山区面积的63％,各河系多年乎均输沙量之和为1.75亿吨,其严重程度仅次于黄河。建国后,党中央和国务院对水土保持和山区建设十分重视,在国家的大力支持下,海河流域山区的广大群众做了大量的水土保持工作,涌现出许多成功的水土保持典型。党的十一届三中全会后,1982年召开了全国第四次水土保持会议,国务院发布了《水土保持工作条例》,随着农业各项经济政策的落实,海河流域的水上保持工作有了新的发展。
Haihe River (including Luanhe River) mountainous area of 189,700 square kilometers, accounting for 59.5% of the total basin area. The whole basin is divided into 8 river systems, fan-shaped distribution, the upper reaches of the river system is very serious soil erosion, according to statistics, the drainage area of about 120,000 square kilometers, accounting for 63% of the mountainous area, The sum of the amount of 175 million tons, the severity of the second only to the Yellow River. After the founding of the People’s Republic of China, the CPC Central Committee and the State Council attached great importance to water and soil conservation and mountainous areas construction. With the strong support of the state, the masses of people in mountainous areas of the Haihe River Basin have done a lot of soil and water conservation work, and many successful examples of soil and water conservation have emerged. Following the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, the Fourth National Conference on Soil and Water Conservation was held in 1982 and the State Council promulgated the “Regulations on Soil and Water Conservation,” and with the implementation of all agricultural economic policies, the water conservancy work in the Haihe River Basin has been completed New development.
