The Three Gorges Reservoir region in China is the Yangtze River Economic Zone’s natural treasure trove. Its environment has an important role development. unique and fragile ecosystem River’s prone to disasters, including soil erosion, landslides, debris flows, earthquakes. Therefore, better alleviate these threats, accurate comprehensive assessment of susceptibility this area required. In study, based on collection relevant data existing research results, we applied machine learning models,...
The leaf equivalent water thickness (EWT, g cm −2 ) and fuel moisture content (FMC, %) are key variables in ecological environmental monitoring. Although a variety of hyperspectral vegetation indices have been developed to estimate the EWT FMC, most these defined considered two or three specific bands for plant species, which limits their applicability. In this study, we proposed new spectral absorption (SAI 970 , SAI 1200 1660 various types by considering symmetry at nm, nm heterogeneity...
A 7.0-magnitude earthquake occurred in Jiuzhaigou County, Sichuan Province at 21:19:46 on August 8, 2017. The epicenter was located the core scenic spot of Jiuzhaigou. triggered thousands rockfalls and landslides, causing serious damage to landscape such ad Panda Sea also infrastructure roads geological disasters vegetational cover steep mountainous areas are difficult identify. Traditional ground surveys optical remote sensing not very applicable. This brought potential risks reconstruction...
Leaf equivalent water thickness (LEWT) is an important parameter in ecological and environmental monitoring. Our study proposes two new indices, the normalized differential projection index (NDPI) distance ratio (DPRI), by considering angle of βSWIR1 length, projection, relationships among random forest feature bands at 721, 1466, 2061 nm, corresponding to NIR, SWIR1, SWIR2 wavebands, respectively. Single-factor analysis NDPI DPRI multifactor other vegetation indices are used build a LEWT...
On August 8, 2017, an earthquake of magnitude 7.0 on the Richter scale occurred in Jiuzhaigou, Sichuan, causing significant damage to both life and property. Traditional geological hazard investigation is difficult Jiuzhaigou because high altitude, high‐altitude canyons, vegetation‐covered seismic areas. This study explores technical advantages using airborne LiDAR technology penetrate vegetation gather information directly from surface, rapidly acquiring 3D point cloud data Through...
Abstract. A magnitude 7.0 earthquake struck Jiuzhaigou County, Sichuan Province at 21:00 on August 8, 2017, and the epicentre was located in major tourist spot of Jiuzhaigou. This paper describes surveying mapping project post-earthquake hazards regions for restoration reconstruction purposes. The triggered thousands collapses landslide disasters, causing severe damage to land scapes scenic roads such as Panda Sea. geological steep mountains slopes dense vegetation area are highly concealed....
