A critical approach to achieving dual carbon targets is maintain strong decoupling (SD) between land use emissions (LUCE) and ecological environment quality (EEQ). However, the spatiotemporal mechanisms of LUCE EEQ at county scale remain understudied. This study aims explore dynamics across 107 counties in Shaanxi Province from 2000 2020. Using PIE-Engine Google Earth Engine, we constructed Remote Sensing Ecological Index (RSEI) models applied Tapio theory analyze trends. The results reveal that 2020, tripled, while increased by 20.93%, albeit with fluctuations. County-level variations exhibited pronounced heterogeneity, types undergoing significant transitions over 95% counties. In 2005, 28.04% achieved a decoupled state, but this deteriorated sharply when nearly half displayed negative (SND), no maintained SD. These findings suggest SD remains challenging requires targeted strategies based on regional characteristics. offers theoretical practical framework for understanding county-level decoupling, which crucial sustainable development.

Given the escalating issue of global climate change, it is imperative to comprehend and quantify effects land use change on carbon storage (CS), which pertains not only preservation ecosystem functions but also directly influences equilibrium stability cycle. This study examines correlation between CS forecasts future spatial distribution CS, offers a reference for rational planning watershed space. Focusing Bosten Lake Basin Xinjiang in China, employing simulation (PLUS) model integrated valuation services trade-offs (InVEST) forecast stocks across three developmental scenarios, while examining shift center gravity autocorrelation their distribution. The findings derived from are as follows: (1) From 1990 2020, predominant type was grassland, there an upward trend areas cropland, forest land, built-up wetland, alongside downward water, unused land. (2) In long term, regional exhibits trend, with most significant increase anticipated EPS scenario. Grassland constitutes extensive reservoir Basin, wetlands exhibit highest sequestration potential. (3) alteration associated expansion or reduction major reservoirs types characterized by (4) consistent pronounced observed under EPS.

The topography of the border ecological barrier area in southern Yunnan is complex, and utilizing vertically projected to estimate carbon stocks may lead significant errors. This study uses multisource data multiple models investigate spatial temporal variations surface factors affecting them area. Results show: difference between planar large, changes land use stock based on this are more significant, showing an inverted V-shape trend time a distribution pattern "high southeast, low northwest". NDVI slope were dominant factors. results provide new surface-scale perspective for deeper understanding land-use planning mountainous region represented by zone Yunnan.

It is of great practical significance to utilize the agricultural carbon emission reduction effect policy re-designation counties as cities or city districts (RCCD) achieve high-quality development. This paper uses panel data 39 in Yangtze River Delta region China from 2010 2022, and adopts a staggered difference-in-difference model threshold identify causal impact RCCD on emissions (ACE). We show that: (1) Overall, exerts tangible dampening ACE, with experimental group exhibiting significant 0.069 compared control post-implementation policy. (2) A dual-threshold environmental regulation emerges context RCCD, wherein ACE varies depending level regulation. (3) The notable inhibitory influence urban high urbanization levels, underdeveloped regions central regions. (4) Agricultural green technology progress plays mediating role relationship between ACE.

Regional carbon budget and compensation are one of the current research hotspots, which is great practical significance for dealing with climate change promoting coordinated development low carbon. Based on energy consumption land use data, a measurement model was established to analyze characteristics spatial differentiation 11 prefecture-level cities in Jiangxi Province from 2010 2020 carry out functional zoning, further calculate value each city. The results showed that (1) during study period, emissions an increasing trend, average annual growth rate 6.00 million tons, showing distribution pattern “high west east.” province mainly represented by net sources. (2) During forest main sink. sink absorption capacity declined 60.56 tons 59.69 2020. (3) regional difference economic contribution coefficient relatively tiny. ecological support has apparent heterogeneity, feature south north.” (4) could be divided into four regions: area, low-carbon optimization total control intensity area. By calculating according value, high-compensation areas, three low-compensation compensated areas. larger is, higher amount; conversely, smaller budget, more amount can obtained. According above conclusions, should improve emission reduction mechanisms strengthen management utilization. Meanwhile, formulate differentiated development, strategies developed promote low-carbon, coordinated, sustainable among regions.
