摘要
黑龙江省境内国境界河总长度 2 0 75km ,由于界河历年江岸的冲刷、切滩改道、主流变化和岔道发展 ,造成界河国土流失 ,情况非常严重 ,通过对江岸坍塌分析 ,找出其主要原因为地形因素、气象因素、河床地质因素、人为因素和弯道环流作用因素所造成的 ,从而为今后国土防护工程提出更加可靠的工程措施。
The country boundary rivers in Heilongjiang Procince are total 2,705 kilometers long. Because of riverside erosion, beach movement, main riverbed change and development, soil erosion is very seious. By analgzing the cause of bank collapse we can drew a conclusion that the topography, climate riverbed foundation, human activity and circling flow action of river are relative to the collapse. Brom up on that, we can make more reliable projects measure to protect the water and soil.
