摘要
坡面水文连通性定量表征指标主要有径流流路长度、染色示踪法、连通性指数、相对地表连通函数、地形湿度指数、方向性渗透指数等,综合分析认为,水文连通性未来的研究应聚焦于以下几个方面:(1)强化不同区域的坡面水文连通性对比研究;(2)明确不同坡面条件对水文连通性的影响机制;(3)建立坡面水文连通性定量表征方法体系;(4)解析土壤侵蚀与坡面水文连通性的关系。
Quantitative indicators of slope hydrological connectivity mainly include runoff channel length,staining tracer method,connectivity index,relative surface connectivity function,topographic humidity index,directional permeability index,etc.According to the comprehensive analysis,the future research of hydrological connectivity should focus on the following aspects:(1)strengthen the comparative study of hydrological connectivity of slope in different regions;(2)Define the influence mechanism of different slope conditions on hydrological connectivity;(3)Establish the quantitative characterization method system of slope hydrological con-nectivity;(4)Analyze the relationship between soil erosion and slope hydrological connectivity.
