Widespread application of water-saving measures, especially advanced drip irrigation technologies, may significantly impact on the land use, and further potentially alter regional ecological environments in an arid area. In this study, remote sensing geographic information system technology were used to analyze LANDSAT images (1976-2015) MOD16 evapotranspiration data (2000-2015) Manas River Basin (MRB), China where technologies have experienced past 40 years. Our results show that area...

Understanding the mechanism of complicated hydrological processes is important for sustainable management water resources in an arid area. This paper carried out simulations movement Manas River Basin (MRB) using improved semi-distributed Topographic hydrologic model (TOPMODEL) with a snowmelt and topographic index algorithm. A new algorithm proposed to calculate curve internal tangent circle on conical surface. Based traditional model, indicator temperature considered solar radiation used...

Rapid socio-economic development has had a significant impact on land use/cover (LULC) changes, which bring great pressure to the ecological environment. LULC changes affect ecosystem services by altering structure and function of ecosystems. It is significance reveal internal relationship between service value (ESV) for protection restoration environments. In this study, based spatial temporal evolution values in Manas River basin from 1980 2020 considering economic benefits, we coupled...

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...

Cotton is the most important cash crop in Xinjiang but low utilization rate of water and fertilizer restricting healthy development this industry. At present, there a lack nitrogen management optimization methods based on multi-objectives cotton use efficiency (WUE), (NUE), yield, income. A continuous field experiment was conducted during 2017–2018 to study effects water–nitrogen coupling growth, WUE, NUE, partial factor productivity, quality, economic benefits under drip irrigation northern...

Abstract: This study was carried out to explore the effects of leaching salinity under subsurface drainage and mulched drip irrigation on saline alkaline land from year 2012 2014in Xinjiang Region China. Three sampled points were both set up in ditch areas. Soil samples obtained at varied depths. Through observing underground water table each point measuring electrical conductivity (EC) soil extracts, following results obtained: (1) after draining, ranged 1.6 m 2.2 area, 1.5 area. Thus,...

Winter irrigation affected the movement of soil moisture, temperature, and salt, which was an effective improvement measure widely used in seasonal freeze–thaw areas. In this paper, we investigated effects different salinized cotton fields (mild salinization (S1), 5.15 g·kg−1; moderate (S2), 8.17 severe (S3), 11.15 g·kg−1) winter rates (W0, 0 m3·hm-2; W1, 3000 W2, 3600 W3, 4200 m3·hm-2) on salinity, growth The results showed that temporal spatial dynamics rate degree were significantly...

The physical and chemical characteristics of soil water sources affect desert plants’ growth, which is essential for the ecological protection in arid areas. typical patch patterns Haloxylon ammodendron oasis-desert ecotone southern margin Manas River Basin consists bare patches (BP) vegetation (VP). H. were studied using stable isotope technology, properties monitored analyzed. results showed that moisture presented a reversed “S” type curve, total salt content an curve. A “wet island”...

Saline soils pose complex environmental challenges that limit fruit tree root function. Understanding the mechanisms by which factors drive traits in zone soil is crucial for improving productivity through irrigation-based regulation of structure. This study aimed to identify primary drivers and driving environment on traits, as influenced water content saline trees. A 2-year field experiment was conducted Korla, Xinjiang, investigate effects physicochemical properties, enzyme activities,...

The economic belt on the north slope of Tianshan Mountains is a highly productive area in Xinjiang, but with rapid development economy and industry acceleration urbanization recent years, fragile ecological environment region has further deteriorated. Exploring shifts land utilization across different eras regions, along transformation terrain configurations, provides key perspectives that can propel sustainable societal environmental growth within this particular area. research analyzed...

Abstract Drip irrigation with brackish water is crucial for the efficient use of scarce resources and ecological restoration. A 2‐year study was conducted to examine effects drip on soil physicochemical properties desert plant Haloxylon ammodendro n which essential in maintaining balance areas.
