一、泥沙处理概述新三义寨引黄灌区实施后,沉沙条渠每年清淤的泥沙都堆放在沉沙条渠左岸60～100m,右岸200～250m的狭长区域内,平均堆高5～6m。对沉沙清淤堆成区,三义寨分局会同有关科研院所积极研究采取相关技术措施,不断研究探讨泥沙农田化新技术、新措施,对已堆成区域及时平整改造,种树、种草、打井灌溉,恢复土地耕种功能。近几年来陆续植速生杨树12万株,堆成区复种160多公顷。200多公顷的黄沙岗变成了人造林场和复垦农田,较好的改善了当地的农业生产环境,遏制了沙荒沙害的发生。
I. Overview of sediment treatment After the implementation of the new SanyiZhai Diversion Irrigation District, the sediment dredged in the sediment discharge each year is deposited in a narrow area of 60-100m on the left bank of the sediment channel and 200-250m on the right bank, 5 ~ 6m. Silt dredging into the area, Sanyi Zhaizi branch with the relevant research institutes to actively study and adopt relevant technical measures, continue to study and explore new technologies and new measures of sediment farming, the area has been piled into a timely transformation, planting trees, Planting grass, irrigation wells, restore land cultivation function. In recent years, one after another planting 120,000 poplar trees, piled into more than 160 hectares of area. More than 200 hectares of Huangshagang has become a man-made forest farm and reclaimed farmland, which has better improved the local agricultural production environment and prevented the occurrence of sand-desert sand disaster.
