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 ：
自2014年起，福建省排污权交易开始试行。经过8年多的试点工作，福建省排污权交易的制度体系趋于完善，交易平台的建立与措施的多样化促进了排污权交易市场的发展。为了改善生态环境、推动绿色发展、促进人与自然和谐共处和实现减排目标，必须不断探索与发展，寻找适合福建省排污权交易的发展道路。由于福建省排污权交易实行时间尚短，许多方面尚无法系统地论证其有效性。根据福建省排污权交易试行至今的现实情况，系统回顾了福建省排污权的发展过程，分析其不足并提出对策建议，以期对福建省排污权交易的进一步完善提供帮助。

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.
