Shuitu Baochi Xuebao目的通过解析东北典型黑土区小流域沟系特征和不同级别沟道形态差异，探索侵蚀沟和河道划分方法。方法选取黑龙江省宾县典型黑土分布区的小流域（14.59 km²），基于无人机影像及其生成高精度数字高程模型，利用Strahler河网分级法对永久性沟道进行分级。结果小流域沟道线密度为3.87 km/km²，各级沟道数量随着等级增加呈指数递减趋势。1级沟道数量占比最高（64.60%），2级沟道的长度和面积占比最大（分别为37.62%和29.57%），4级以上沟宽明显增大，5~6级的沟长、沟宽和面积均明显高于低等级沟道，

Shuitu Baochi Xuebao[目的] 为探究不同植物群落切沟系统之间以及同一切沟不同部位间植被生长特性的差异。[方法] 以陕西省安塞区纸坊沟小流域5个典型植物群落切沟系统为研究对象,系统研究其物种多样性、盖度、地上生物量、枯落物蓄积量和地下生物量等植被生长特性。[结果] (1)地上生物量、枯落物和根系消减系数受植被类型的显著影响,表现为乔木切沟>灌木切沟>草本切沟,盖度表现为灌木切沟>草本切沟>乔木切沟;(2)切沟右壁(阳坡到半阳坡)物种多样性指数、盖度小于左壁(阴坡到半阴坡);(3)受水热条件综合影响 ...

Shuitu Baochi Xuebao目的明确长时间尺度切沟发育特征，探究切沟侵蚀的显著影响因子，为气候变化背景下青藏高原水土流失治理提供理论参考。方法基于1970年和2025年高分辨率遥感影像，获取念青唐古拉山西段东南麓冲洪积扇的稳定沟、发育沟和新形成沟形态参数特征与发育速率，采用Spearman相关性分析发育沟的发育速率、新形成沟形态特征的显著影响因子。结果2025年稳定沟、发育沟和新形成沟的平均沟长分别为265.42、401.61、123.12 m，平均面积分别为12 350.93、7 517.52、1 055.36 m2 ...
