Green technology innovation, containing economic, social and ecological triple value effects, plays an important role in promoting regional high-quality development. In this paper, we take the Central Plains city cluster, one of China’s top ten national clusters, as research object use super-efficiency SBM-DEA model to measure analyze its green innovation efficiency. The panel spatial Durbin (SDM) is used empirically investigate market-based, policy factors that affect efficiency cluster....
ABSTRACT Coastal mud belts, which lie parallel to the coast just seaward of shoreface, are one most important settings where shallow‐marine muddy deposits accumulate. However, sedimentary processes and facies distributions coastal belts remain largely uninvestigated. This study uses process‐oriented sedimentology, coupled with provenance analysis organic geochemistry records at northern entrance Taiwan Strait, investigate largest such systems in world, Changjiang belt. Carbon‐14 dates...
<title>Abstract</title> Studying the identification of hazardous karst collapse pillars(KCPs) is vital for ensuring safe mining coal resources. However, current study on identifying KCPs primarily emphasizes physical detection, overlooking spatial aggregation patterns. In this study, we proposed a hotspot method using Moran's index. and carry out experiments in Wangpo Coal Mine Shanxi, China. The involves evaluating by considering their morphological characteristics combination Analytic...
A vast theoretical and empirical literature has been devoted to exploring the relationship between environmental regulation total factor productivity (TFP), but no consensus reached reason may be attributed fact that resource reallocation effect of is ignored. In this paper, we introduce misallocation in process discussing impact on TFP, taking China’s provincial industrial panel data from 1997 2017 as a sample, spatial econometric method employed investigate whether affects TFP. The results...
The acoustic properties of seafloor sediments on continental slopes play a crucial role in underwater propagation, communication, and detection. To investigate the characteristics spatial distribution patterns slope, geoacoustic experiment was conducted northwestern South China Sea. covered two sections: one crossing shelf slope downslope direction, other near break along-slope direction. In situ techniques, sediment sampling, laboratory measurements were used to acquire data (such as sound...
Abstract It has long been recognized that ocean gravity waves can generate microseisms through their interactions and coupling with the solid earth. Their generation mechanisms, wave types, propagation have studied debated intensively. In this study, we focus on characteristics of in South China Sea (SCS) compare them globally observed microseisms. We use data from six bottom seismometers, 10 publicly available broadband land seismometers near SCS, a reanalyzed global height model 1 May 2012...
Seafloor sediment acoustics is a burgeoning field of marine scientific research. In situ measurement technique key for investigating acoustic properties. Establishing correlation between in parameters and physical great significance advancing the theory seafloor acoustics. This study employed an system to measure sound speed attenuation various types sediment, such as sand, silty clay, clayey silt. The results showed that were strongly curvilinear correlated with properties, wet bulk...
We investigated the impact of environmental regulation on total factor productivity (TFP) based a panel dataset 284 cities at prefecture-level and above in mainland China from 2006 to 2020 examined whether had resource reallocation effect thus affected TFP. The results showed that there was an “inverted U-shaped” pattern TFP moderate strengthening helped increase TFP, which still held after endogeneity treatment robustness tests. relationship between eastern, central, western held, while did...
Abstract The crust near an extinct mid‐ocean ridge provides unique constraints on how its accretion and deformation responded to the cessation of spreading. Here we present crustal thickness Vp / Vs measurements beneath 11 Ocean Bottom Seismograph sites that cross South China Sea's spreading axis. We find oceanic crust, which generally had only slight changes once started, abruptly thins at close Abnormally high ratios are obtained several south ridge, indicating presence serpentine. These...
China has very long coastline, but special surface conditions make it difficult to conduct ground magnetic and marine geomagnetic surveys over beach–shallow sea transition areas such as mariculture areas, harbours, wharfs; a result, survey data cannot be linked continental data, giving rise missing data. To address this issue, an aeromagnetic technology based on unmanned autonomous helicopter is proposed. Not only capable of surveying the area inaccessible vehicles vessels its high...
Deep-towed multichannel seismic exploration technology has better applicability and more development potential when utilized to invert the geoacoustic properties of deep-sea sediment. The accurate geometric inversion results receiving array are crucial for fine submarine sediment imaging physical property parameter based on deep-towed data. Thus, this study presents an geometry method suitable complex seafloors address challenge precise source-receiver positioning. objective function is...
ABSTRACT Contourites (contour‐current deposits) are commonly associated with deep‐water environments, but this study documents a shallow‐water, muddy contourite drift in the centre of Taiwan Strait. The body (water depths 30 to 70 m, 220 km long, 50 wide, 0 m thick), its long axis approximately colinear Strait Current, is flanked on both sides by moats. Compositional data show that composed sediment carried northward Current from Choshui River draining Taiwan. coast‐normal Changyun Ridge...
