Under the influence of climate change, hydrological processes glaciers have undergone significant changes, a fact which is seriously affecting agricultural production in downstream region Tianshan Mountains, China. In order to explore intrinsic relationship between change and elements, we proposed an “evaluation-driving-prediction” system study it. First, constructed glacier-enhanced soil water assessment tool model (GE-SWAT) used two-stage calibration method optimize parameters. Next,...

Abstract The inland river basins of northwestern China are structured as mountain-basin systems. Water resources originate in the flow-producing area (FPA), utilized and operated oasis dissipated desert area. In this study, a Soil Assessment Tool (SWAT) model was constructed Manas River Basin (MRB) FPA. Meanwhile, it simulated climate change runoff evolution trends FPA MRB under different four scenarios Coupled Model Intercomparison Project Phase 5. main findings showed that (1) years...

Water scarcity is a major issue in arid regions, and it crucial to have an accurate understanding of water resource utilization for informed decision-making regarding water-related issues. However, due various reasons such as inadequate measuring facilities, the actual agricultural usage often underestimated. The concept methodology footprint, based on life-cycle perspective, provide powerful tool studying agriculture. By utilizing theories models footprints, method reviewing regions...

A prerequisite for the rational development and utilization of regional water resources is measurement stress. In this study, from perspective footprints, we took proportion agricultural footprint within total resource usage Xinjiang (hereafter referred to as XJ) an example measure its stress index explore state in region corresponding driving factors. The ESDA method was applied characterize spatial patterns correlations with effects different factors on differentiation between were...

Ili River, the main river in Lake Balkhash basin. This study introduces a novel hybrid model by coupling Soil and Water Assessment Tool (SWAT) hydrological with machine learning algorithms. It aims to simulate forecast streamflow of clearly delineating roles meteorological factors anthropogenic process change. During period 1960–2020, contribution climate change variation was 104.59%-113.07%, land use ranged from −10.75% −4.59%, impact reservoir construction −2.27%. The predictive outcomes...

The Ebinur Lake Basin is an ecologically sensitive area in the arid region of northwest China. In recent years, ecological environment basin has continued to deteriorate, and ecosystem function been seriously degraded. However, among functions Basin, water production considered be core upholding equilibrium security basin. Water can reflect environmental service function, which essential for economic vitality well-being factors that impact yield are diverse; moreover, these, climate change...

Abstract Ecological conservation and restoration have increasingly captured attention worldwide due to the degradation of ecosystems. As one most ecologically fragile areas, Tarim River Basin, Xinjiang, China, encountered serious decline desert riparian forests. The Chinese government has implemented “Ecological Water Conveyance Project” (EWCP) since 2000, protecting restoring dominant natural species forests, i.e., Populus euphratica Oliv. regenerative effect after water conveyance was...

Accurately identifying and predicting droughts can provide local managers with a basis for decision-making. The Xinyang region is prone to floods, which have large impact on agriculture socio-economics. This paper employs precipitation data from the scientific drought flood control measures in this region. are first treated standardized indices (SPIs) three-month, six-month, nine-month time scales. Subsequently, Morlet wavelet analysis performed each of three scales analyzed SPI. results...

The shallow groundwater of the quaternary system in Baoshan basin, Yunnan Province is seriously polluted, threatening human health and restricting local socio-economic development; therefore, it necessary to investigate hydrochemical characteristics formation mechanisms basin.
