The protection and sustainable management of cultivated land are cornerstones ensuring ecological balance. In implementing policies, spatially defined land-use strategies can aid in the utilization these resources. Yet, recent agricultural activities have affected water quality Yellow River pose a significant challenge to basin. Many policy considerations overlooked ecosystem integrity. To address this oversight, we targeted cities bordering main course Henan Province constructed an security...
Optimizing the land use structure is one of most effective means improving surface water aquatic environment. The relationship between patterns and quality complex due to influence dams sluices. To further investigate impact on in different basins, we Shaying River as an example, which a typical tributary Huai Basin. Utilizing 2020 data monitoring from two periods, this study employs GIS spatial analysis, Random Forest Model, redundancy Partial Least-Squares Regression quantitatively explore...
Protecting the water quality of Yellow River is great significance to ecological protection Basin. The identification spatiotemporal variations environment and implementation measures control non-point source (NPS) pollution are both key improving quality. Between 2012 2021, we conducted assessments eight indicators, including temperature, dissolved oxygen (DO) pH, chemical demand (CODMn), five-day biological (BOD5), total phosphorus (TP), NO3-N, NH3-N at six sites in main stream Henan. We...
Accurate runoff prediction plays a pivotal role in facilitating effective watershed management and the rational allocation of water resources. Given inherent challenges posed by nonlinear nonstationary nature sequences, this study introduces novel coupled model, combining complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), variational (VMD), long short-term memory (LSTM), Informer techniques for monthly at Wulong hydrological station Yangtze River Basin from 1973 to...
Determination of heavy metal (HM) contamination, ecological risks, and sources in river sediments are important to preventing controlling environmental pollution. This study investigated the spatial distribution, potential biological toxicity five metals Huanghua City water diversion area from Yellow River, China. GIS, redundancy analysis (RDA), positive matrix factorization (PMF) model were used accurately quantify pollution distribution sources. The results revealed that Cu had highest...
Abstract Water pollution is a globally significant issue. environment simulation an important tool to study water pollution. In order investigate the impact of hydrological periods, quality indicators and cross-sections on capacity, we took Luo River in Luoyang City as example, used MIKE21-coupled hydrodynamic model segmentation method calculate capacity COD, TP, NH3-N wet, normal, dry periods under L1 (Gao Yazhai-Lilou), L2 (Li Lou-Baimasi), L3 (Baimasi-G207 Highway Bridge) section. The...
