During the county scale, there was a significant positive spatial autocorrelation. ② The general panel regression design indicated that GDP, building land location, population, per capita GDP, and per capita deposit stability of banking institutions were significantly correlated with carbon emissions, while the former three had the strongest marketing effect on carbon emissions. ③ The goodness of fit for the geographically and temporally weighted regression model was large, while the way and power associated with the various other effect aspects changed considerably in spatial-temporal qualities, except that GDP showed a stable advertising effect globally. The outcomes indicated that carbon emission amounts and main influencing factors diverse among counties in China. This study revealed the heterogeneity of carbon emissions at the county amount, that is helpful to optimize the spatial-temporal execution road for the "dual carbon" target.In this study, rice straw, soybean straw, wheat-straw, and corn straw were plumped for as garbage, and biochars had been ready through the pyrolysis technique at 550℃ under oxygen-limited circumstances to investigate the physicochemical properties of biochars derived from the straws, the migration and change faculties of heavy metals (HMs) (Cr, Ni, Cu, As, Cd, and Pb) after pyrolysis, and their leaching habits in different leaching solutions. The outcome revealed that the physicochemical properties and elemental structure of this biochars were basically constant. But, weighed against compared to biochars derived from other straws, biochar derived from wheat straw had a higher ash content (22.48
