2017-2018年黄土丘陵沟壑区第一副区桥沟流域重力侵蚀观测数据集

本数据集为2017-2018年黄土丘陵沟壑区第一副区桥沟流域重力侵蚀观测数据集。重力侵蚀观测采用定点监测，方法主要为测针法—完成点位量测、拍照，测量侵蚀位移。数据集主要包括定点监测记录表。数据加工方法是定点监测辛店沟和桥沟小流域（二支沟）已布设的典型点位，拍照并测量侵蚀位移，两期对比分析固定点位侵蚀变化。

This dataset is the gravity erosion observation dataset of the Qiaogou Watershed in the first sub-region of the Loess Hilly and Gully Region during 2017-2018. Gravity erosion observation was conducted via fixed-point monitoring, mainly adopting the pin measuring method, which includes point position measurement, photography, and erosion displacement measurement. The dataset mainly consists of fixed-point monitoring record sheets. The data processing method involves conducting fixed-point monitoring at the pre-arranged typical points in the Xindian Gully and Qiaogou Small Watershed (Second Branch Gully), taking photos and measuring erosion displacements, and performing two-phase comparative analysis of the erosion changes at these fixed points.
