杨庄滞洪工程位于河南省西平县城西22km的小洪河干流上,属“河道型”滞洪区,控制流域面积1026km2,滞洪库容2.55亿m3。杨庄滞洪区若调整为水库后,可继续发挥拦蓄洪水的作用,提高下游防洪除涝标准,同时可减少老王坡进洪机遇,减少淹没损失;增加有效灌溉面积,改善农业生产条件,为粮食生产安全做出贡献;为西平县城及水库下游乡镇提供生活及工业水源;可发展旅游业和水产养殖等,为区域经济发展起到重要作用。因此把杨庄滞洪区调整为杨庄水库是可行的。
The Yangzhuang Flood Retarding Project is located on the main stream of Xiahong River with a radius of 22km to the west of Xiping County, Henan Province. It is a “river-type” detention basin with a controlled drainage area of 1026km2 and a detention flood storage capacity of 255 million m3. Yangzhuang detention area, if adjusted to a reservoir, can continue to play the role of interception of floods to improve downstream flood control and waterlogging standards, but also to reduce Wang Lao slope flood opportunities and reduce flooding losses; increase the effective irrigation area, improve agricultural production conditions for Contribute to the safety of food production, provide living and industrial water for the towns and villages in the lower reaches of Xiping County and the reservoir, develop tourism and aquaculture, and play an important role in the development of regional economy. Therefore, it is feasible to adjust Yangzhuang flood detention area to Yangzhuang Reservoir.
