一、水利工程措施概况为治理河北省的水旱灾害,解放以来,进行治水改土综合治理,收到十分显著的成效。主要的工程措施有以下几方面: 1.在山区修建水库,拦洪截沙,调节径流,发展灌溉,兼取防洪兴利之益。从1956年兴建陡河水库开始,至今已建成20座大型水库、34座中型水库及上千座小型水库,总库容130多亿立方米。水库控制的集水面积占山区总面积的比例;在海河南系为81％,海河北系为98％;滦河及冀东沿海约70％。经水库拦洪调节后,各河中下游防护区的防洪标准普遍提高
I. Summary of Water Conservancy Measures In order to control floods and droughts in Hebei Province since the liberation, comprehensive control over water and soil has been received, and remarkable results have been achieved. The main engineering measures are the following aspects: 1. In the mountains to build reservoirs, flood intercept sand, regulating runoff, irrigation development, and take advantage of the flood control benefit. Starting from the construction of Douhe Reservoir in 1956, 20 large reservoirs, 34 medium reservoirs and over a thousand small reservoirs have been built up to date, with a total storage capacity of over 1.3 billion cubic meters. The proportion of reservoir-controlled catchment area to the total mountainous area is 81% in the Haihe River and 98% in the Haihe River and 70% in the Luanhe and Jidong coasts. After the flood control of the reservoir is adjusted, the flood control standards of the middle and lower reaches of the river generally increase
