Three-dimensional (3D) models provide the most intuitive representation of geological conditions. Traditional modeling methods heavily depend on technicians’ expertise and lack ease updating. In this study, we introduce a deep learning-based method for 3D implicit modeling, leveraging substantial dataset drilling data. By applying resampling normalization techniques, standardize data significantly expand dataset, making it suitable training neural networks. Utilizing characteristics sample...
Potential landslides in the mountainous areas of southwest China pose a serious threat to lives and property local residents. Synthetic aperture radar interferometry (InSAR) technology has advantages wide coverage, all weather applicability, low cost can quickly accurately identify large range active landslides, making it useful geodetic tool for early identification prevention landslides. This paper employed small baseline subset InSAR (SBAS−InSAR) ascending descending Sentinel−1 data from...
Abstract Dryland ecosystems exist in various vegetation landscapes with contrasting compositions of vascular plants and biocrusts (surface‐soil mats comprised soil particles, cyanobacteria, lichens, mosses fungi), they are very vulnerable to ongoing global change. However, compared plants, the responses their coexistence change remain elusive. We conducted a 5‐year experiment involving multi‐level precipitation nitrogen addition desert shrubland northern China examine these responses. found...
Considering the great time and labor consumption involved in conventional hazard assessment methods compiling landslide inventory, construction of a transferable susceptibility prediction model is crucial. This study employs UAV images as data sources to interpret typical alpine valley area Beichuan County. Eight environmental factors including digital elevation (DEM) are extracted establish pixel-wise dataset, along with interpreted data. Two models were built, each deep neural network...
Forests are facing various threats, such as drought, in the context of global climate change. Canopy water content (CWC) is a crucial indicator forest stress, mortality, and fire monitoring. However, previous studies on CWC have not adequately simulated forests with heterogeneous discontinuous canopy structures. At same time, there lack field validation. This study retrieved across contiguous U.S. (CONUS) coupled radiative transfer models (RTMs) random (RF) algorithm. A Gaussian copula prior...
Nitrogen (N) deposition has been well documented to cause substantial impacts on ecosystem carbon cycling. However, the majority studies of stimulating N by direct addition forest floor have neglected some key ecological processes in canopy (e.g., retention and absorption) might not fully represent realistic atmospheric its effects In this study, we stimulated both understory (50 100 kg ha−1 year−1) with a local NHx:NOy ratio 2.08:1, aiming assess whether had similar soil respiration (RS)...
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...
Abstract. Soil carbon isotopes (δ13C) provide reliable insights at a long-term scale for studying soil turnover. The Tibetan Plateau (TP), called “the third pole of the earth” is one most sensitive areas to global climate change and exhibits an early warning signal warming. Although many studies detected variability δ13C site scales, knowledge gap still exists in spatial pattern topsoil across TP. To fill substantial gap, we first compiled database with 396 observations from published...
Elevated nitrogen (N) and phosphorus (P) depositions have greatly affected belowground carbon processes in forest ecosystems. However, open questions still remained on the effects of N P processes, including soil respiration (RS), its source components—autotrophic (RA) heterotrophic (RH), total allocation (TBCA) Moso bamboo forests—one most important types with wide distributions subtropical China. To fill this knowledge gap, a two-year N, P, NP experiment was conducted forests. Results...
Stress events induced by global warming pose severe threats to vegetation health. Assessing the impact of these stress on health and growth ecosystems in China is crucial. This study constructed three assessment systems selected one that most effectively reflects By identifying characteristics events, employing trend analysis, sensitivity anomaly change modified residual this explores dynamic changes their responses across from 2001 2020. The results indicate Pressure–State–Response (PSR)...
南阿尔金木纳布拉克地区原划为长城纪巴什库尔干岩群中陆续识别出多类型高压变质岩,以及新元古代和古生代的原岩年龄信息。本文在前人研究的基础上,对木纳布拉克地区巴什库尔干岩群的中-低压浅变质岩进行详细的野外调查,并对三个不同岩组的6个样品进行了岩相学、锆石U-Pb定年和Hf同位素组成研究,以期对区内长城纪地层的构造归属划分提供更多的年代学证据。LA-ICP-MS锆石U-Pb定年测得红柳泉组钾长片麻岩和角闪片岩的原岩形成年龄分别为1459~1577 Ma和<1493 Ma、贝壳滩组钙质白云母片岩的原岩年龄为<956 Ma,均为中-新元古代;此外钙质白云母片岩还获得499...
