大坝的建设阻隔了河流的连续性,影响了大坝下游河流的生态结构和功能。本文分析了大坝对河流结构的影响以及龙羊峡的生态环境状况。从整个区域的水生态保护着手,研究了龙羊峡下游河流的泥沙含量的变化,揭示大坝的生态保护是河流生态恢复的重要措施。
Construction of dam blocks the continuity of river and affects the ecological structudownstream river. In the paper, the influence of the dam on river structures and ecological environment condition ofLongyangxia are analyzed.
