摘要: 重庆黔江区滑坡灾害发育,而斜坡坡度是影响其发育的重要因素之一。为定量化研究斜坡坡度与滑坡发育的关系,将坡度划分为9个取值区间,分析不同坡度对滑坡数量、面积和体积的贡献情况,采用均值法迭加统计,得到坡度对滑坡发育的综合贡献程度。结果表明坡度15°~30°对滑坡贡献程度最高,坡度10°~15°和30°~40°次之,坡度小于10°及大于40°贡献程度最低。研究结果符合实际,可为黔江区滑坡危险度区划提供可靠依据。

Abstract: The landslide hazard is serious in Qianjiang district, and the slope gradient is an important factor that affects the development of landslide hazard. To make a quantitative analysis on the relationship between slope gradient and landslide development, the slope gradient was divided into 9 value intervals, and the contribution rates of different slope gradients to landslides’ number, area and volume were analyzed. The results show that slope gradient in the range of 15°~30° makes highest contribution to landslide growth, slope gradient in the range of 10°~15° and 30°~40° contributes secondly, and slope less than 10° and more than 40° contributes lowest. The results correspond with the actual situation, which can provide a reliable basis for landslide hazard zoning in Qianjiang district.
