Effects of Agricultural Large‐And Medium‐Sized Reservoirs on Hydrologic Processes in the Arid Shiyang River Basin, Northwest China

Water Resources Research, Journal Year: 2023, Volume and Issue: 59(2)

Published: Jan. 30, 2023

Abstract Agricultural large and medium‐sized reservoirs in arid regions increase the water stresses within local hydrologic systems, adding to pressures on aquatic ecosystems also threatening sustainability of resources. Yet, there is limited research concerning how agricultural affect hydrology inland river basins, which has hampered a comprehensive assessment sustainable use these systems. We explore stable isotopes evaluate effects Shiyang River basin. Results show that large‐ this region alter isotopic patterns increasing water‐body evaporation enriching composition near reservoir. As result, losses reservoir can be as high 30.7% downstream desert reservoirs. Reservoir exchanges with surrounding groundwater contributes 22% precipitation due evaporation. Detailed studies individual most enriched at surface then gradually depletes toward bottom. The cumulative effect multiple medium sized profoundly alters processes leading an evaporation‐led loss

Spatiotemporal Changes in Ecological Quality and Its Associated Driving Factors in Central Asia

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(14), P. 3500 - 3500

Published: July 21, 2022

Maintaining the ecological security of arid Central Asia (CA) is essential for sustainable development CA. Based on moderate-resolution imaging spectroradiometer (MODIS) data stored Google Earth Engine (GEE), this paper investigated spatiotemporal changes and factors related to environment quality (EEQ) in CA from 2000 2020 using remote sensing index (RSEI). The RSEI values during 2000, 2005, 2010, 2015, were 0.379, 0.376, 0.349, 0.360, 0.327, respectively; unchanged/improved/deteriorated areas 2000–2005, 2005–2010, 2010–2015, 2015–2020 about 83.21/7.66%/9.13%, 77.28/6.68%/16.04%, 79.03/11.99%/8.98%, 81.29/2.16%/16.55%, respectively, which indicated that EEQ was poor presented a trend gradual deterioration. Consistent with trend, Moran’s I 0.905, 0.893, 0.901, 0.898, 0.884, revealing spatial distribution clustered rather than random. high–high (H-H) mainly located mountainous areas, low–low (L-L) distributed deserts. Significant regions H-H L-L, most reached significance level 0.01, indicating exhibited strong correlation. affected by both natural human factors. Among factors, greenness wetness promoted EEQ, while heat dryness reduced had greater effects other three indexes. Human such as population growth, overgrazing, hydropower are important affecting EEQ. This study provides environmental protection regional planning semi-arid regions.

Quantifying the contributions of climate factors and human activities to variations of net primary productivity in China from 2000 to 2020

Frontiers in Earth Science, Journal Year: 2023, Volume and Issue: 11

Published: Feb. 24, 2023

Net primary productivity (NPP) plays a vital role in the globe carbon cycle. Quantitative assessment of effects climate changes and human activities on net dynamics is for understanding driving mechanisms vegetation change sustainable development ecosystems. This study investigates contributions climatic factors to China from 2000 2020 based residual trend analysis (RESTREND) method. The results showed that annual average was 325.11 g C/m 2 /year significantly increasing ( p <0.05) at rate 2.32 /year. increased across 40.90% over period, while only 1.79% declining <0.05). increase were 1.169 1.142 /year, respectively. Climate contributed positively mainly Sichuan Basin, Loess Plateau, Mongolian Northeast Plain. Positive occurred Central China, Greater Khingan Mountains. varied among sub-regions. In Tropical Monsoon Region Subtropical Region, had greater impacts than factors, dominant factor recovery other addition, during 2000–2020, dominated by both 49.84% areas solely accounted 13.67% 10.92%, Compared changed land cover types, total as well mostly unchanged which more 90%.
