[Display omitted] • Visualization and quantitative analysis of the global ecological carbon sinks and sources. • Enhance the prediction of carbon sequestration dynamics under climate change. • Climate change potentially affecting the carbon-climate feedback. • Research content is becoming clearer and more systematic. • Keyword clustering the classification of the research into six relatively independent subtopics. Climate change is extensively affecting the global ecosystem, especially the ecosystem carbon sequestration and sequestration potential, which are issues of global concern. The proposed concept of "carbon neutrality" in 2020 has brought ecological carbon sequestration to the forefront. Therefore, the research on climate change and ecosystem carbon sequestration need to be systematically reviewed, summarized, and examined. Based on the Web of Science database, this paper analyzed 4005 articles (1992–2022 year) after rigorous screening via a bibliometrics analysis and then presented the research trends and future research focus of ecological carbon sequestration. The following conclusions are drawn: (1) the research over the last 30 years has steadily improved, and the annual number of publications has increased in a cubic polynomial fashion (R 2 = 0.9937), with 87.57 % of the total publications appearing after 2009. Global Change Biology and Science of the Total Environment are the most influential journals in the field; (2) participation in such research is becoming increasingly common with expanding research areas covering Eurasia, America, Oceania, and Africa. The United States and China are the most productive and influential countries; (3) the diversity of this research is increasing, and the research content is becoming more explicit and systematic. Most research focuses on climate change, carbon sequestration, management, land-use changes, and nitrogen and soil organic carbon; (4) although traditional ecological evaluation techniques were essential early on, remote sensing and modeling have become the primary methods for assessment; (5) keyword clustering allows the classification of the research into six relatively independent subtopics: climate change and terrestrial ecosystems, sequestration and organic-carbon, ecosystem services, nitrogen and carbon cycling, biomass and forest, and blue carbon, which provides a reference for further research on ecological carbon sequestration and carbon neutrality.

• We analyse the research progress of ecosystem service cascade in recent ten years. • We discuss the advantages and disadvantages of different ecosystem service research frameworks. • We look forward to the future development of ecosystem service cascade. Ecosystem service cascade (ESC) links each component of ecosystem services with social value, building an interdisciplinary research bridge between natural science and social science, which can help decision-makers better integrate the concept of ecosystem services into decision-making. This paper combed the content of the concept of ecosystem services cascade effect, reviewed the research progress of the cascade effect found: ESC due to its structure feature and flexibility, can help researchers to more fully understand the concept of ecosystem services to promote interdisciplinary communication, constantly adjust the structure of the ESC and scope in order to improve the applicability of the model in different research. ESC is widely used in ecosystem service mapping and regional policy regulation. Through literature review, We get the following understanding ①The purpose of research often determines the definition of services and policy preferences, a clear definition of the system will improve the applicability of the ESC framework. ②Assess the wishes and connections of stakeholders and quantify the forms of human participation and impact on each component in the cascade framework, clarify the development characteristics and driving mechanism of Human -Natural relationship, identify the feedback process and quantify the positive and negative feedback cycle.③Quantitatively simulate the impact and regulation of climate change and socio-economic development on regional development under different regional development scenarios. Construct the optimization index system of ESC components to provide schemes and Countermeasures for regional sustainable development. [ABSTRACT FROM AUTHOR]

[Display omitted] • Transfers of wetland cover types lead to indirect impacts on water conservation. • Climate change is a dominant and direct factor impacting wetland water conservation. • The Dongting and Poyang Lake wetlands exhibited different evolution patterns of water conservation. • The InVEST model is applicable for quantitatively evaluating lake wetland water conversation. Water conservation is the core wetland ecological function. The pattern of water conservation in geography often exhibits local spatial heterogeneity. In this paper, the Dongting Lake (DT) and Poyang Lake (PY) wetlands were taken as research objects, and the water yield (WY) module of the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model was used to spatially quantify water conservation, with the aim of revealing the differences in water conservation in homogeneous wetlands. We observed spatio-temporal changes in the WY over six periods from 1998 to 2018 and used multivariate analysis of variance (MANOVA) and the system cluster method to explore the patterns and driving factors of water conservation in the DT and PY wetlands. The research results were as follows: (1) the WY in the two wetlands showed declining trends, but the trend in the DT wetland was more obvious. (2) Water conservation in the PY wetland exhibited a more sensitive response to climate than water conservation in the DT wetland. (3) From the perspective of the WY level, the PY wetland was generally high, while the DT wetland was generally low. (4) Climate change was the main contributor to and direct driving factor of water production, while wetland changes and socio-economic factors were indirect driving factors. (5) The effect of wetland cover changes on the WY showed significant differences among wetland cover types, indicating that the drivers of the WY changes had a clear relationship with landscape changes and transfers in wetland cover types. (6) The InVEST model was applicable for evaluating lake wetland water conservation. In summary, paying more attention to the differences in the changes in heterogeneous and homogenous regions can help us understand the factors that impact water conservation. Additionally, rational adjustment of indirect driving forces is conducive to ecological safety management. [ABSTRACT FROM AUTHOR]
