Liaozhong Sag is an important hydrocarbon-bearing area in the Bohai Bay Basin. During deposition of Shahejie Formation, provenance system within and outside basin was complex with variable lithologies, leading to remarkable reservoir heterogeneity obscure effects on development. Based detrital zircon U-Pb dating petrological analysis, eastern western systems Formation were interpreted. The results show that zircons are predominately Archean Cretaceous age, material composition sandy...
Abstract Radio occultation (RO) refractivity observations provide information about tropospheric water vapor and temperature in all weather conditions. The impact of using RO on analyses forecasts Hurricane Ernesto’s genesis (2006) an ensemble Kaman filter data assimilation system is investigated. Assimilating profiles the vicinity storm locally moistens analysis lower troposphere also adjusts wind both upper through forecast multivariate correlations wind. model propagate enhance added...
Planning the analyses of spatial distribution and driving factors forest fires regionalizing fire risks is an important part management. Based on Landsat-8 active dataset Liangshan Yi Autonomous Prefecture from 2014 to 2021, this paper proposes optimal parameter logistic regression (OPLR) model, conducts risk zoning research under analysis scale model parameters, establishes a prediction model. The results showed that unit in study area was 5 km accuracy OPLR about 81%. climate main factor...
Gully erosion is the main cause of global land degradation. The factors controlling gully at watershed scale have been extensively studied, but spatial pattern gullies and their primary environmental are unclear. In order to explore regional over thousands square kilometers, 34 sample areas were selected in northeastern China 10 proposed. Based on interpretations from high-resolution Google Earth images analysis, kernel density estimation (with polyline features), correlation results show...
A gully system is an important indicator that reflects the development of regional topography and landforms, one most factors affecting gullies. However, at present, research on impact systems in mountainous area Ningnan dry-hot valley still needs to be strengthened. In order study characteristics gullies influence systems, based both visual interpretation remote sensing images field investigations, five topographic (elevation, slope gradient, aspect, relief, dissection) were employed three...
A phoslactomycin-producing actinomycete, designated strain NEAU-ML8T, was isolated from a millipede (Kronopolites svenhedind Verhoeff) and characterized using polyphasic approach. 16S rRNA gene sequence analysis showed that NEAU-ML8T belongs to the genus Streptomyces with highest similarities lydicus NBRC 13058T (99.39 %) chattanoogensis DSM 40002T (99.25 %). The maximum-likelihood phylogenetic tree based on sequences isolate formed distinct phyletic line S. 40002T. This branching pattern...
The contribution of early human activity to the increase in atmospheric CH 4 content during middle late-Holocene is still debated. quantitative reconstruction past changes land use by rice agriculture a key resolving issue, because large uncertainties exist current prehistoric estimates, owing lack direct records. In this study, we used combination archaeological data (the area and distribution sites) an improved model (PLUM) determine spatiotemporal throughout Yangtze River Valley, China,...
Accurate quantification of gully shoulder lines (gully borderlines) will help better understand formation and evolution. Surveying mapping are the most important ways to obtain precise morphology. To evaluate influences different steps surveying curve-fitting methods on morphology line characterized by fractal dimensions, 13 at heads were surveyed using a total station then mapped with curve fitting, dimensions calculated maps compared those measured in field. Fractal field measurement...
Gully erosion is well-developed in the Jinsha dry-hot valley region, which has caused serious soil losses. volume regarded as an effective indicator that can reflect development intensity of gully erosion, and evolutionary processes gullies be predicted based on dynamic variation volume. Establishing prediction model essential to determine accurately conveniently. Therefore, this work, empirical was constructed verified detailed morphological features acquired by elaborate field...
Characterizing gully cross sections (GCs) is essential for calculating the volume and erosion rate of gully. However, little research has focused on modeling morphology GCs. This study investigated 456 GCs with a laser distance meter located at mouth, middle, head 152 gullies in Yuanmou Dry-hot Valley China; mapped them AutoCAD software; fitted 2nd–6th degree polynomial functions, discussed correlation between coefficients The results showed that: (1) using 2nd-degree function (y = ax2 + bx...
Rill erosion is well developed in Yuanmou Dry-hot Valley. The appearance of step-pools rills (SPRs) an early stage and necessary condition for rill development. We measured length, width, depth plunge pools, height, slope step walls. observed the developmental environment every SPR field. Through research on relationships among parameters, morphological characteristics, control factors, we conclude that (1) correlations with pool length width are not evident (p > 0.1); height < depth,...
