People's governments at various levels shall take measures to strengthen the rehabilitation of small river basins, control hazards of sand storms, prevent and control soil erosion and desertification. 各级人民政府应当采取措施,加强对小流域治理,控制风沙危害,预防和治理水土流失、土地沙化。
And strengthen the management of sand basin and consolidate the managed achievements. 强化沉沙池管理,巩固治理成果。
In addition, In the thesis, with barycenter line change to analyse and research the theory of bed development rule, combine GPS real-time location capability to strengthen the Yangtse River pick sand to put forward for the first time. 此外,论文还首次提出了以重心线变化来分析研究河床演变规律的理论、结合GPS实时定位功能加强长江采砂监管等。
Therefore, the judgment of the meandering river ancient flow direction, combined with the modern method of stratigraphic correlation, can improve and strengthen the random walk modeling of meandering river sand body morphology and channel simulation. 因此,利用判断曲流河古水流方向,再结合现代地层对比方法,可以完善和加强随机游走建模方法对曲流河砂体形态及河道模拟的研究。
