利用海岸带沉积物中保存的代用指标，重建全新世气候适宜期（HCO）红树林林的发育过程，可以了解未来全球变暖背景下红树林生态系统对亚洲季风的响应。根据广西钦州湾沉积物中总有机质的来源，将其划分为三个端元：红树林衍生的、陆源的和海洋的植物营养素，采用有机碳同位素（δ 13 Corg）和总有机碳/总氮摩尔比（C/N）描述的三端元模型。红树林衍生的有机物（碳）的贡献的百分比被用来作为红树林发展的代理。三个可见的下降，发生在约。7.3，ca. 6.9，所以。6.2 cal. ka BP的变化与相对稳定的较高的CO2贡献水平相对应，表明钦州湾在HCO期间发生了3次明显的红树林退化。三次红树林退化大致对应于亚洲冬/夏季风加强/减弱的时间。这表明，即使在有利于红树林发展的时期，如HCO，极端气候，如由加强/减弱的亚洲冬/夏季风驱动的寒冷和干燥事件，也会引发红树林的退化。
The response of mangrove ecosystems to the Asian monsoon in the future global warming can be understood by reconstructing the development of mangrove forests during the Holocene climatic optimum (HCO), using proxies preserved in coastal sediments. The total organic matter in sediments of a segmented core, with calibrated age ranges between 5.6 and 7.7 cal. ka BP and corresponding to the HCO, from the Qinzhou Bay in Guangxi, China, is quantitatively partitioned into three end-members according to their sources: mangrove-derived, terrigenous, and marine phytoplanktonic, using a three-end-member model depicted by organic carbon isotope (δ13Corg) and the molar ratio of total organic carbon to total nitrogen (C/N). The percentage of mangrove-derived organic matter (MOM) contribution is used as a proxy for mangrove development. Three visible drops in MOM contribution occurred at ca. 7.3, ca. 6.9, and ca. 6.2 cal. ka BP, respectively, are recognized against a relatively stable and higher MOM contribution level, indicating that three distinct mangrove forest degradations occurred in the Qinzhou Bay during the HCO. The three mangrove forest degradations approximately correspond to the time of the strengthened/weakened Asian winter/summer monsoon. This indicates that even during a period favorable for the mangrove development, such as the HCO, climatic extremes, such as cold and dry events driven by the strengthened/weakened Asian winter/summer monsoon, can trigger the degradation of mangrove forests.
