黄河河南省湿地において、土壌と植物の有機炭素分布を調査。12地点でサンプリングし、表層土壌（0-20cm）に炭素が集中し、植生タイプが土壌有機炭素の空間変動に強く影響することを発見。総炭素貯蔵量は約8.93×10^6 t Cと推定され、低土壌炭素密度・高植物炭素蓄積という特徴的なパターンが確認された。

This study investigated the distribution of soil and plant organic carbon in the Henan Yellow River wetland, China. Sampling at 12 sites revealed that soil organic carbon (SOC) concentrated in the top 0-20 cm layer, with vegetation type strongly influencing SOC spatial variation. Total carbon storage was estimated at approximately 8.93×10^6 t C, exhibiting a pattern of low SOC density but high plant carbon accumulation.

日本のGX文脈において
中国黄河湿地の炭素分布を定量化した事例。日本でも湿地の炭素吸収源評価に応用可能。ただし直接的な日本のGX政策（SSBJ等）との関連は薄い。
In the global GX context
Provides empirical data on carbon storage in regulated riparian wetlands, supporting nature-based climate solutions globally. Although China-specific, the methodology can inform carbon accounting in similar ecosystems under the framework of natural climate solutions.
👥 読者別の含意
🔬研究者:Offers detailed field data on carbon partitioning in a regulated wetland, useful for carbon cycle modeling.
🏛政策担当者:Highlights the carbon storage potential of wetlands, supporting conservation and restoration as climate mitigation strategies.
📄 Abstract（原文）
Context The Yellow River in Henan has undergone major hydrological changes due to reservoir water-sediment regulation, leading to the development of extensive seasonal wetlands. Aims This study examined organic carbon distribution in the Henan Yellow River wetland by measuring soil and plant organic carbon across different vegetation zones. Methods Twelve sampling sites were selected; three 1 m × 1 m quadrats were set for each vegetation type. Plant tissues (0–50 cm soil layer) and soil samples were collected to analyze total organic carbon. Key results Soil organic carbon (SOC) was concentrated in topsoil (1.57–7.10 g kg−1), with density 0.61–4.14 kg m−2. Plant organic carbon density dominated aboveground biomass: grass highest, Tamarix lowest. Total wetland carbon storage was ~8.93 × 106 t C. Conclusions SOC concentrations were substantially higher in the 0–20 cm layer than in the 20–50 cm layer. Vegetation type strongly influenced the spatial variation in SOC, whereas total plant organic carbon (POC) was mainly allocated to aboveground biomass. The wetland exhibited a distinctive carbon pattern characterised by low soil organic carbon density but relatively high plant organic carbon accumulation. Implications We measured the distribution characteristics of organic carbon in the Henan Yellow River Wetland and identified a pattern of low soil carbon density coupled with relatively high plant carbon density, providing a basis for further research on carbon cycling in regulated riparian wetlands.
