2016-2019年藏东南扎木弄巴滑坡观测数据

本数据集为2016-2019年藏东南扎木弄巴滑坡观测数据，该站位于西藏自治区波密县易贡乡，易贡乡扎木弄沟位于南巴迦瓦峰北北西侧，易贡藏布左岸，地势上西高东低，其地貌类型属于高山地貌，流域面积29.4km2，区域内地质构造的隆升显著，扎木弄沟地处易贡-通麦-波密断裂带的相对隆升区的边缘，这些隆升区由一系列的横向构造影响，区域成为周期或准周期滑坡泥石流灾害的易发区。该观测站详细记录滑坡相关数据，数据由布设现场的翻斗式降雨量传感器、土壤温度传感器、空隙水压力传感器、含水量传感器、水势传感器、振动传感器测得，采集频率10分钟/条，由CR1000数据采集器取得原始数据，土壤温度、孔隙水压力、含水量、水势、振动这些参数采用日平均数据并整理，降雨数据采用日累计数据并整理。 站点名称：扎木弄巴滑坡观测站,经纬度：94 °56′54,30°11′13,海拔高程：2550米数据内容：降雨量单位为毫米（mm），土壤温度单位为摄氏度（℃），孔隙水压力单位为千帕（Kpa），含水量单位为容积率（m3/m3），水势单位为帕（pa）， 振动单位为加速度(g）This dataset contains landslide monitoring data collected from 2016 to 2019 at the Zhamunongba Landslide Monitoring Station, which is located in Yigong Township, Bomi County, Tibet Autonomous Region. The Zhamunong Gully in Yigong Township lies on the north-northwest side of Namcha Barwa Peak and the left bank of the Yigong Zangbo River. The terrain slopes west to east, and the landform is classified as alpine landscape. The drainage area of the gully is 29.4 km². The region exhibits significant tectonic uplift, and Zhamunong Gully is situated at the edge of the relatively uplifted zone of the Yigong-Tongmai-Bomi fault zone. These uplifted zones are influenced by a series of transverse structures, rendering the region a periodic or quasi-periodic landslide and debris flow disaster-prone area. The monitoring station comprehensively records landslide-related data. The data were collected by on-site deployed sensors including tipping-bucket rainfall sensors, soil temperature sensors, pore water pressure sensors, volumetric water content sensors, water potential sensors and vibration sensors, with a sampling frequency of one record every 10 minutes. Raw data were acquired using a CR1000 data logger. Daily average data were processed for soil temperature, pore water pressure, volumetric water content, water potential and vibration parameters, while daily cumulative data were processed for rainfall data. Station Name: Zhamunongba Landslide Monitoring Station; Coordinates: 94°56′54″E, 30°11′13″N; Elevation: 2550 m. Data Details and Units: Rainfall: millimeters (mm); Soil temperature: degrees Celsius (℃); Pore water pressure: kilopascals (kPa); Volumetric water content: m³/m³; Water potential: pascals (Pa); Vibration acceleration: gravitational acceleration (g).
