Abstract ：
Microbial carbon use efficiency (CUE) typically promotes soil organic carbon (SOC) storage in terrestrial ecosystems. However, this relationship remains poorly understood in coastal wetlands, where tidal flooding creates unique environmental conditions, facilitates lateral transfer and SOC loss, and mediates organic matter exchange between terrestrial and marine systems. Here we examined the CUE-SOC relationship across a tidal flooding gradient (4-25 % frequency) in a subtropical coastal wetland. Along this gradient, SOC decreased by 65 % while microbial CUE increased from 0.24 to 0.32. This inverse relationship coincided with marked compositional shifts: plant debris declined from 57 % to 18 %, while microbial necromass increased from 21 % to 35 %. The enhanced CUE was accompanied by increased turnover times alongside decreased metabolic quotient (qCO2), C-acquiring enzyme activities, soil basal respiration, and microbial biomass carbon (MBC). This enhanced efficiency stemmed from substrate-microbe interactions rather than environmental stresses, as communities transitioned from oligotrophic taxa (alpha-proteobacteria, Basidiomycota) specializing in recalcitrant terrestrial substrates to copiotrophic microorganisms (gamma-proteobacteria, Bacteroidota, Ascomycota) efficiently metabolizing labile marine compounds. Contrary to terrestrial patterns, enhanced CUE did not promote SOC storage due to three key mechanisms: (i) enhanced CUE from marine substrates could not compensate for declining plant debris accumulation; (ii) reduced microbial biomass limited necromass formation despite higher CUE; and (iii) metabolic benefits from high CUE (reduced enzyme activities and respiration rates) could not offset the substantial decrease in SOC inputs. Our findings reveal distinct CUE-SOC relationships in coastal wetlands compared to terrestrial ecosystems, highlighting the importance of considering both terrestrial and marine processes in understanding carbon cycling in these transitional environments.

Abstract ：
The deterioration of the urban thermal environment has seriously affected the quality of life of urban residents, and studying the optimal cooling landscape combination and configuration based on local climate zones (LCZs) is crucial for mitigating the thermal environment. In this study, the LCZ system was combined to analyze the spatial and temporal changes to the thermal environment in the central area of Fuzhou, and the 159 blocks in the core area were selected to derive the optimal LCZ combination and configuration. The conclusions are as follows: (1) From 2013 to 2021, the building layout of the study area became more open and the building height gradually increased. The high-temperature areas were mainly clustered in the core area; (2) The LSTs for low-rise buildings (LCZ 3 (41.67 degrees C), LCZ 7 (40.10 degrees C), LCZ 8 (42.61 degrees C), and LCZ 10 (41.85 degrees C)) were higher than the LSTs for high-rise buildings (LCZ 1 (38.58 degrees C) and LCZ 4 (38.50 degrees C)); (3) The thermal contribution index for low building types was higher for dense buildings (LCZ 3 (0.4331), LCZ 8 (0.3149), and LCZ 10 (0.2325)) than for open buildings (LCZ 6 (0.0247) and LCZ 9 (0.0317)); (4) Blocks with an average LST of 36 degrees C had the most cost-effective cooling, and the combination and configuration of LCZs within such blocks were optimal. Our results can be used to better guide urban planners in managing LCZ combinations and configurations within blocks (the smallest planning unit) at an earlier phase of thermal environment design, and for appropriately adapting existing block layouts, providing a new perspective on urban thermal environment research with important implications for climate-friendly city and neighborhood planning.

Abstract ：
The urban heat island (UHI) effect will persist for a long time and influence human health, energy consumption, and future urban planning. Understanding the cooling effect of water bodies and green spaces can help alleviate the frequency of extreme climate, especially during torridity seasons. In this study, correlation and regression analysis were used to measure the relationship between land surface temperature (LST) or cooling indicators and landscape factors. In addition, the cooling intensity, distance, and threshold value of efficiency (TVoE) of water bodies and green spaces were detected. The results confirmed that: first, the cooling effect of water bodies were stronger than that of vegetation in most cases and more water bodies' layout in the region was advocated; second, increasing vegetation coverage within 27% of the region can effectively and economically alleviate the thermal environment; and third, the green samples with an area of 0.57 ha and a high vegetation index had a higher cost performance ratio. The results provided quantitative guidance for urban public service spatial planning of water bodies and green spaces to prevent the continuous increase of urban background temperature.

Abstract ：
With the acceleration of global warming and urbanization, the problem of the thermal environment in urban areas has become increasingly prominent. In this paper, Fuzhou was selected to quantify the impact of land use cover change (LUCC) on land surface temperature (LST). The results showed that from 1993 to 2016, the land use/cover types of the study area changed greatly, especially the change of construction land, which led to an obvious change in the spatial pattern of LST. From 1993 to 2016, the spatial and temporal distribution of LST contributions in Fuzhou was uneven. The central urban area had a positive contribution to the rise of LST, while Minqing and Yongtai had a negative contribution. From the perspective of different land use/land cover types, forest or grass land, cultivated land, and water all made a negative contribution to the increase of surface temperature, while construction land made a positive contribution. Outcomes provided by the multi-distance spatial cluster analysis (Ripley's K function) showed that there was a scale effect in the concentration and dispersion of LST; from 1993 to 2016, the concentration range of LST in the study area gradually expanded and the degree of concentration increased.

以福州主城区绿色空间为研究对象,基于遥感手段,研究绿色空间的复杂演化对地表温度扰动的影响.研究发现:(1)1993-2016年,福州主城区下垫面绿色空间损失和扩张面积分别为46.50km2和4.73km2,面积差达到41.77km2.(2)不同温度区的分布格局发生了较大变化,冷岛区面积大幅减少,热岛区面积显著增加.从各温度等级内的土地利用分布来看,低温区内分布较多湿地和水体,次低温区以林/草地为主.(3)城市热岛重心与城市重心的迁移方向有关;而城市冷岛重心与城市绿色空间的分布关系密切.(4)不同绿色空间演化过程引起的降温效应大小依次为:绿色空间扩张＞绿色空间不变＞绿色空间交换＞绿色空间损失.绿色空间扩张带来的平均降温幅度约为5.0℃,而绿色空间损失引起的平均增温约为7.0℃.不同的演化过程下,通过增加等面积的绿色空间,并不能抵消先前绿色空间损失带来的升温.因此,科学合理的绿色空间规划对于有效缓解城市热岛至关重要.

Abstract ：
随着全球变暖和城市化进程的加快,城市区域的热环境问题日益凸显.以福州为例,基于遥感、地理信息系统和地统计学等方法,通过多尺度空间模式,定量分析以地表温度贡献度为表征的城市热环境时空变化及其特征.结果 表明:①1993-2016年,研究区的土地利用/覆盖类型发生了显著变化,建设用地净增长1 231.04 km2,变化率高达295.33％;耕地被建设用地占用.②地表温度空间格局变化明显,中高温区以闽江水域为轴向周边区域逐渐蔓延,低温区和次低温区面积显著减少.③1993-2016年,福州所辖各县市区地表温度贡献时空分布不均.其中,中心城区(鼓楼区、台江区、仓山区、晋安区和马尾区)对地表温度上升表现为正贡献,闽清县和永泰县表现为负贡献.从不同土地利用/覆盖类型来看,林/草地、耕地、水体对地表温度升高有负贡献,建设用地表现为正贡献.④多距离空间聚类分析(Ripley''s K函数)显示,地表温度集聚与分散存在尺度效应;1993-2016年,研究区的地表温度集聚范围逐步扩大、集聚程度增强.
