南阳市淅川县丹江口水库大坝加高后,水库正常蓄水位由157 m提高到170 m,库周肥沃良田几乎淹没殆尽。为了有效保护和合理利用库区即将淹没的耕作层土壤,丹江口库区淅川库周将淹没的优质耕作层土壤剥离转移到交通便利、海拔在172 m以上且距库岸较近的瘠薄土地上,同时配套进行土地平整、农田水利建设。通过合理布设各种水土保持工程措施和植物措施,项目建设过程中产生的水土流失将得到有效的控制,不仅项目区生态环境得到改善,而且还可以产生良好的社会效益和经济效益。
After the dam of Danjiangkou Reservoir in Xichuan County of Nanyang City was raised, the normal reservoir water level increased from 157 m to 170 m, and the fertile farmland in the reservoir bank almost drowned. In order to effectively protect and make rational use of the tillage soil to be submerged in the reservoir area, the subsoil of high-quality tillage soils in the Danjiangkou reservoir area was transferred to an infertile land at an altitude of more than 172 m and near barren land, At the same time supporting the formation of land, farmland and water conservancy construction. Through rational arrangement of various soil and water conservation engineering measures and plant measures, soil erosion in the project construction will be effectively controlled. Not only the ecological environment in the project area will be improved, but also good social and economic benefits will be generated.
