With the accelerating changes of land use/cover caused by natural and human factors, landscape pattern has undergone significant changes. Given scarcity water resources degradation ecological functions in arid semi-arid regions China, it is necessary to analyze impact on conservation. Taking Wei River Basin (WRB) as research area, based balance equations, FRAGSTATS 4.2 software, correlation analysis method, this study explored spatiotemporal distribution characteristics conservation WRB from...

The source region of the Yellow River (SRYE) is located in eastern part Tibetan Plateau a major water production and conservation area for River. This study aims to investigate correlations between streamflow meteorological factors/ocean SRYE from 1960 2018 using wavelet analysis. effects signals on were calculated Partial Least Squares-Structural Equation Model (PLS-SEM). Furthermore, climate factors with strong correlation used as inputs random forest (RF) multiple linear regression (MLR)...

The Loess Plateau is ecologically vulnerable. Vegetation the key factor in ecological improvement. study of distribution patterns vegetation and its impact factors has important guiding meaning for construction region. existing single sensor cannot provide long-term high-resolution data. We established data NDVI with a great spatial resolution by fusing GIMMS MODIS based on ESTARFM. Furthermore, we analyzed variation under different topographies response to climatic human activities Plateau....

Understanding the impact of climate change and human activities on runoff is crucial for water resources management. However, an evaluation available methods analysing this lacking. In study, we comprehensively reviewed four commonly used quantitative methods: Soil Water Assessment Tool (SWAT) model, Budyko-based approach, two empirical methods, i.e., Double mass curve (DMC) Modified DMC (MDMC). Using Wei River basin as a case assessed reduction influenced by from 1970 to 2017. The results...

Abstract The Weihe River has experienced a significant runoff decline in the past few decades, but detailed and systematic analysis of different sub‐regions basin (WRB) for long time is insufficient. Based on data five hydrological stations from 1957 to 2018, this study investigated variation annual both whole (WWRB) its sub‐regions: upper, middle, lower reaches (URWR, MRWR, LRWR, respectively), Jing (JRB), Beiluo (BLRB). Moreover, contribution climate change anthropogenic activities was...

Land resources are closely intertwined with human survival, making it crucial to explore the spatiotemporal changes and driving forces of land use. In this study, Yan River Basin in Loess Plateau was selected as study area. The Mann–Kendall trend test, Pettitt’s landscape pattern indices, other methods were employed characteristics factors use change from 1990 2020. results indicate that: (1) areas forest impervious showed a significant increasing suddenly changed 2004. Change-point years...

Abstract Background Urban ecological health is crucial for the long-term sustainable development of watershed. Accurately evaluating level environment helps to develop reasonable strategies restoration and resource management. This paper constructed a comprehensive evaluation index system based on Pressure-State-Response (PSR) framework evaluated eleven administrative regions in Wei River Basin (WRB), northwest China 1980, 2000, 2020 using an model established by fuzzy mathematics. Further,...

Extreme precipitation events bring considerable risks to the natural ecosystem and human life. Investigating spatial-temporal characteristics of extreme predicting it quantitatively are critical for flood prevention water resources planning management. In this study, daily data (1957–2019) were collected from 24 meteorological stations in Weihe River Basin (WRB), Northwest China its surrounding areas. We first analyzed change extremes WRB based on space- time cube (STC), then predicted using...

Abrupt runoff reduction in the Wei River Basin (WRB) has attracted extensive attention owing to climate change and human activities. Nevertheless, previous studies have inadequately assessed respective contributions of variability activities on different spatial scales. Using Mann–Kendall Pettitt’s methods, this study identified long-term (1970–2018) changes hydro-meteorological variables. Furthermore, Budyko-based method was used quantify influence at scales WRB, including whole three...

Quantitatively assessing the characteristics of river streamflow variation and conducting research on attribution identification are basis for formulating climate-change response strategies rational use water resources. Based daily data Zhuangtou Hydrological Station in 1970–2018, this paper analyzes changes Beiluo River Basin studies impact climate change anthropogenic activities basin. A non-parametric Mann–Kendall test Pettitt’s were used to determine trend detect abrupt baseflow. The...

The flood season is the main period for runoff and sediment yield, understanding variations of events great significance distinguishing runoff-sediment processes in Loess Plateau. In this study, we analyzed at event scale Qiaogou catchment investigated influencing factors. results showed that were mainly produced by rainfall with short duration heavy intensity study area. Based on 28 corresponding precipitation data from reference (P-I, 1986–1989) revegetation (P-II, 2001–2009), catchment, a...

Wei River is the largest tributary of Yellow River, and in recent decades, water resource has changed significantly. Identifying characteristics influencing factors streamflow change needed for development effective management strategies economic region entire basin. The analyzations were based on records from 1957 to 2018 at five hydrological stations as well precipitation air temperature data 22 meteorological stations. Mann-Kendall method Pettitt test used analyze trends transition years...
