- S157.1
- 摘要:
- 东北漫川漫岗区位于黑土区核心位置，侵蚀沟发育严重。利用3S获取侵蚀沟数量、长度等数据，计算降雨侵蚀力、坡度、坡长，分析侵蚀沟发育特征及三因素对侵蚀沟发育影响。结果表明：东北漫川漫岗区75.11%的发展沟处于发育初、中期，潜在发育危险性较大，沟蚀剧烈程度地域性差异显著，研究区南、北部沟壑密度分别为0.3，0.06 km/km2；地形、冻融历时、温差等差异造成降雨侵蚀力对北部侵蚀沟发育影响显著，南部相对较弱；研究区坡度与坡长呈正相关关系，北部坡缓造成坡度与沟壑密度呈线性增加关系，南部坡陡造成坡度与沟壑密度呈线性减小关系，北部、南部地形因子与沟壑密度分别呈线性增加、减小关系，随着坡长的增加，沟壑密度先增加后减小，临界坡长为900 m。
- Abstract:
- Rolling hilly region in northeast of China is located in the center of the black soil area where gullies are ubiquitous. We examined gully development characteristics and factors affecting its development by 3S technology, computing rainfall erosivity, slopegradient and slope length. The results show that 75.11 percent of gullies in this area are at early or middle development stage and they have great developmental potential dangers. The intensity of erosion gully development in the study area has significant regional differences, the gully densities in the south and north of study area are 0.3， 0.06 km/km2, respectively. The differences of terrain, freezing-thaw duration and temperature are the main reasons that caused rainfall erosivity, which has significant impacts on gully development in the northern, less impacts on gully development in the southern. Slope gradient and slope length have positive correlations in the study area, slope in the northern area is small and it has positive correlations with gully density, slope in the southern area is big and it has negative correlations with gully density, topographic factors in the northern and southern areas have positive and negative correlations with gully densities, respectively; with the growth of slope length, the gully density increases firstly and then decreases, the critical slope length is 900 m.
