Substantial CO uptake by biomass ashes under natural condition in China.

A considerable amount of biomass ashes, resulting from agricultural waste field burning, wildfire, and solid biofuel incineration, is typically discarded in field or stored in dumps, where the alkaline oxides (CaO, MgO) they contain undergo carbonation and weathering-erosion processes over extended periods, continuously absorbing CO from the atmosphere and soil. However, their CO absorption behavior under natural conditions remains insufficiently explored in China. Using life cycle assessment (LCA) and material flow analysis (MFA) methods, this study developed a CO absorption analysis model for biomass ashes under natural conditions.

[Research progress on biomass ash carbon capture and storage].

Carbon capture and storage (CCS) technology is an important way to slow down the continuous increase in atmospheric CO concentration and to achieve the dual carbon target. Carbon capture and storage through biomass ash is a secure, permanent, and environment friendly way. To better understand the characteristics of biomass ash carbon capture and storage, we summarized progresses on biomass ash carbon capture and storage, clarified the mechanisms of biomass ash carbon sequestration, analyzed the influencing factors, and explored its applications in various domains.

Accuracy and capability of tri-ponderal mass index in assessing cardio-metabolic risk factors in Chinese children and adolescents aged 3 to 17 years, compared with body mass index.

Background: Tri-ponderal mass index (TMI) has been reported to be a more accurate estimate of body fat than body mass index (BMI). This study aims to compare the effectiveness of TMI and BMI in identifying hypertension, dyslipidemia, impaired fasting glucose (IFG), abdominal obesity, and clustered cardio-metabolic risk factors (CMRFs) in 3- to 17-year-old children.

Methods: A total of 1587 children aged 3 to 17 years were included.

Skeleton-Based Human Pose Recognition Using Channel State Information: A Survey.

With the increasing demand for human-computer interaction and health monitoring, human behavior recognition with device-free patterns has attracted extensive attention. The fluctuations of the Wi-Fi signal caused by human actions in a Wi-Fi coverage area can be used to precisely identify the human skeleton and pose, which effectively overcomes the problems of the traditional solution. Although many promising results have been achieved, no survey summarizes the research progress.

[Evaluation of climate regulation service at prefecture-level city: A case study of Fuzhou City, China].

Ecosystem services are the bridge between ecosystem functions and human welfare. Climate regulation service (CRS) has an extremely important role in ecosystem services. It is important to conduct a comprehensive assessment based on the whole process of CRS occurrence for scientific assessment of ecosystem services.

[Contribution of straw disposal to carbon source and sink under the framework of carbon neutrality].

Exploring the spatio-temporal variation characteristics of carbon source and carbon sink under different disposal methods of crop straw is of great significance for optimizing the utilization policy of crop straw resources in China and realizing the goal of maximizing carbon emission reduction and carbon neutralization. Based on data from National Statistical Yearbook, we examined the changing trends of both the amount and value of carbon emission, carbon emission reduction, carbon sink enhancement under different crop straw disposal methods in 31 provinces of Chinese mainland. The results showed that the mean annual carbon emissions of straw burning in China from 2008 to 2019 were 8.

Wetland ecosystem service function and its value accounting:A case study of Fuzhou City, China.

Wetland plays an important role in ecological protection and social development. Scientific and rational evaluation of the values of wetland ecosystem service is the basis of protection and sustainable utilization of wetland resources. How to scientifically and effectively assess the wetland ecosystem gross ecosystem product (GEP) and make it into the national GDP accounting system are the focus of the scientific community and government departments.

Regional ecological compensation accounting in Fuzhou City based on a payment for ecosystem services (PES)model.

The determination of regional ecological compensation quota and spatial selection are key issues in the study of horizontal transfer payment ecological compensation mechanism. Taking 12 districts of Fuzhou City as the basic research unit, we accounted the ecological function values of forest, grassland, wetland, agriculture, and marine ecosystems in 2015 and 2018. Combined with local economic development situation, we constructed an ecological compensation model.

Gross economic-ecological product accounting of Fuzhou City, China.

The gross economic-ecological product (GEEP) accounting is crucial to promote the construction of ecological civilization, and practice the ideas of "lucid waters and lush mountains are invaluable assets". GEEP accounting had been conducted at national and provincial scales, but not at urban scale. According to the economic and ecological development, the GEEP accounting framework was built in Fuzhou City.

Accounting for the cost of ecological degradation in Fuzhou City, China.

Ecological degradation accounting is a critical content of building green GDP and gross economic-ecological product (GEEP) accounting systems. With ecosystems in Fuzhou City as a research object, we built an accounting framework for the cost of ecological degradation according to the unreasonable human activity. Following the accounting framework, we calculated the ecological degradation cost in Fuzhou City of 2015 and 2018.
