The urban heat island effect, triggered by global warming and rapid urbanization, has negatively impacted residents’ lives. It been shown that green space (UGS) can improve the thermal environment. However, stability influencing factors of cooling effect (UGSCE) in context climate change remain unclear. In this paper, we study area within Fifth Ring Road Changchun City, using multi-source remote sensing image data to quantify analyze its on both regional patch scales. results show scale,...

Urbanization is the development trend of all countries in world, but it has caused considerable ecological problems that need to be alleviated by building security patterns. This study took Ningbo as an example construct and optimize pattern. We analyzed land use types, normalized difference vegetation index, landscape connectivity for sources selection. In constructing resistance surface, we considered natural socio-economic factors. On this basis, identified corridors based on a minimum...

Bacteria can facilitate the increase of Mg2+ content in biotic aragonite, but molecular mechanisms incorporation ion into aragonite facilitated by bacteria are still unclear and dolomitization grains is rarely reported. In our laboratory experiments, ions higher than that inorganically-precipitated we hypothesize Mg may enhance subsequent aragonite. this study, was induced Bacillus licheniformis Y1 at different Mg/Ca molar ratios. XRD data show only precipitated media with ratios 6, 9, 12...

The behavior of the global climate system on scales from years to centuries is related several mechanisms, including solar forcing and El Niño-Southern Oscillation (ENSO). However, due limited stratigraphic resolution accuracy dating methods, pre-Quaternary archives are rare. A middle Eocene lacustrine shale in Bohai Bay Basin East China contains annual laminae which provides a site study astronomical varve chronology basin. Principal component analysis sediments cored material, their...

Several studies have revealed that the Eocene fine-grained sedimentary rocks in Bohai Bay Basin is driven by astronomical forces. However it still not clarified how orbital cycles specifically control deposition of and coupling relationship paleoclimate- paleolake- sedimentation. In this study, a combination core thin section observation, X-ray diffraction, ICP-MS analysis, total organic carbon (TOC) content analysis cyclostratigraphy were conducted on lacustrine shale Shahejie Formation...

Pre-Quaternary archives are rare, however, due limited stratigraphic resolution accuracy datings. A middle Eocene lacustrine shale in Bohai Bay Basin (E China) shows annual laminae that allow establishing its astronomical varve chronology.

Abstract Numerous shallow‐marine limestone layers of the Furongian (Late Cambrian) Chaomidian Formation in Jiulongshan section (Shandong Province, China) are breccias. Some these breccias show abundant vertical to sub‐vertical clasts. Typically, clasts end abruptly at contact plane with overlying deposit, either abutting sedimentary bed or via an erosional that truncates A few exposures concentrations must have been uplifted extent they transgressed then surface (possibly) penetrated...

Although biomineralization of minerals induced by microorganisms has been widely reported, the mechanisms and characteristics biominerals precipitated needs to be studied further. In this study, Staphylococcus warneri YXY2, a moderate halophile, was used induce precipitation carbonate at various Mg/Ca molar ratios. To investigate mechanism, growth curve, pH changes, ammonia test, concentration bicarbonate ions, activity carbonic anhydrase (CA) alkaline phosphatase (ALP) were determined....
