Contributing to Better Development of the Modern Civilization of Chinese Nation Celebrating the Opening of the New Museum of the Yin Xu Site

The discovery of Yin Xu has turned the history of the Shang Dynasty into credible history,continuing the trend of integrating civilizations from all directions for over a thousand years,and initiating a pattern of continuous,diversified,and unified civilization for more than three thousand years.With the Yin Xu Site as the fulcrum,it constructs the spatialtemporal system of Xia-Shang archaeology and culture.

豫西黄土区矿山人为坡沟水土流失特征研究

矿山开采形成的坡沟是矿区人为新增水土流失的重要部位和重点防治区域,为了给矿区水土保持综合治理提供科学依据,以豫西黄土区矿山人为坡沟为研究对象,利用概化的黄土区矿山人为坡沟模型,进行历时60 min,雨强分别为66、85、120 mm/h的人工模拟降雨试验,结果表明:同一雨强下产流量、产沙量、径流含沙量、土壤侵蚀模数、输沙率随降雨历时延长而增大,径流含沙量沿程呈逐渐增大趋势,沟坡径流含沙量整体上较坡面的大;雨强越大,产流量、产沙量、径流含沙量、土壤侵蚀模数、输沙率越大,径流含沙量沿程增速越快、增幅越大。应在坡面及其上游、沟道两侧采取截排水措施,将坡面径流有效导向下游,防止径流冲刷坡面和沟道。
