Research progress on the effects of elevated atmospheric CO concentration on CH emission and related microbial processes in paddy fields.

Paddy fields are recognized as significant sources of methane (CH) emissions, playing a pivotal role in global climate change. Elevated atmospheric carbon dioxide (CO) concentrations (e[CO]) exert a profound influence on the carbon cycling of paddy fields. Understanding the effects of e[CO] on CH emissions, as well as the underlying microbial processes, is crucial for enhancing carbon sequestration and reducing emissions in paddy fields.

The quantification of root exudation by an method based on root morphology over three incubation periods.

Investigating the quantity and spatiotemporal dynamics of metabolite release from plant roots is essential if we are to understand the ecological significance of root exudates in the rhizosphere; however, this is difficult to quantify. In the present study, we quantified root exudation rates during three incubation periods (0-24, 24-48, and 48-72 h) and fine roots within four diameter ranges (<0.8, 0.

Analysis on the geographical pattern and driving force of traditional villages based on GIS and Geodetector: a case study of Guizhou, China.

Traditional villages have received widespread attention from all walks of life based on important carriers of Chinese rural culture. The mutual superposition of natural and cultural factors may exacerbate the evolution of traditional village geographical patterns. To understand such relationships and effects, factors and degrees influencing traditional villages need to be determined.

Spatial differentiation and driving mechanism of rural water security in typical "engineering water depletion" of karst mountainous area-A lesson of Guizhou, China.

Southwest China gets abundant rainfall, but in its rural areas, there is a severe shortage of water resources for irrigation and drinking. A case study was conducted in the Guizhou Province, which has the most concentrated karst distribution worldwide. The rural water security index was constructed, and Geodetector and ArcGIS were employed to systematically analyze the status quo, spatial differentiation, and driving mechanism of water security in rural areas of Guizhou in 2016.

Integrated assessment and scenarios simulation of urban water security system in the southwest of China with system dynamics analysis.

The demand for global freshwater is growing, while global freshwater available for human use is limited within a certain time and space. Its security has significant impacts on both the socio-economic system and ecological system. Recently, studies have focused on the urban water security system (UWSS) in terms of either water quantity or water quality.
