Lakes are an important component of the global water cycle and aquatic ecosystem. Lake water quality improvement have always been a hot topic of concern both domestically and internationally. Noncompliant outflow water quality frequently occurs, especially for lakes that rely mainly on irrigation return flow as their water source. External water replenishment to improve the water quality of lakes is

Impact of industrial policy on urban green innovation: empirical evidence of China’s national high-tech zones based on double machine learning Front. Environ. Sci. (IF 4.6) Pub Date : 2024-04-04 Wei Cao, Yu Jia, Benwei Tan
Effective industrial policies need to be implemented, particularly aligning with environmental protection goals to drive the high-quality growth of China’s economy in the new era. Setting up national high-tech zones falls under the purview of both regional and industrial policies. Using panel data from 163 prefecture-level cities in China from 2007 to 2019, this paper empirically analyzes the impact

Satellite-observed precipitation and total column water vapor Front. Environ. Sci. (IF 4.6) Pub Date : 2024-04-03
This study explores the relationship between water vapor and rainfall intensities over three tropical lands (Amazon Basin, Sahel, southern South America) and three tropical ocean regions (Atlantic Ocean, Indian Ocean, Niño 4). We utilized daily total column water vapor (TCWV) data from the Atmospheric Infrared Sounder (AIRS) and daily precipitation records from the Tropical Rainfall Measuring Mission

Chemical weathering in the upper and middle reaches of Yarlung Tsangpo River Front. Environ. Sci. (IF 4.6) Pub Date : 2024-04-03 Yu Cheng, Rui Wang, Zhaofei Liu, Zhijun Yao
This study focused on the chemical composition of the rivers in the middle and upper reaches of the Yarlung Tsangpo River system. Samples were collected in April 2015 to analyze spatiotemporal variation characteristics and determine weathering processes and CO2 consumption using principal component analysis (PCA) and a modified forward model. The TDS on the southern bank of the upper and middle reaches

Main influencing factors of terrestrial evapotranspiration for different land cover types over the Tibetan Plateau in 1982–2014 Front. Environ. Sci. (IF 4.6) Pub Date : 2024-04-02
Introduction: Terrestrial evapotranspiration (ET) over the Tibetan Plateau (TP) has important implications for the global water cycle, climate change, and ecosystem, and its changes and driving factors have drawn increasing attention. Previous research studies have minimally quantified the effects and identified the pathways of the influencing factors on ET over different land surface types. Methods:
