Irrigation Water Redistribution and Competition Mechanisms Between Cropland and Shelterbelts in Arid Regions: Insights from Stable Water Isotopes data

Xinyue Wang, Dongdong Qiu, Guofeng Zhu, Yuanfeng Liu et autres

Abstract. Protective forests play an important role in maintaining the stability of arid oasis agroecosystems; however, water exchange and competition between shelterbelts and cropland under limited water availability remain poorly quantified. This study used stable hydrogen and oxygen isotopes to investigate irrigation-water …

Electrostatic Coordination Salt‐Locking and Anisotropic Thermal Highways for Leakage‐Free Atmospheric Water Harvesting

Xiangbing Wang, Hui Peng, Luhua Wang, Xi Yu et autres

ABSTRACT Sorption‐based atmospheric water harvesting (AWH) offers a decentralized strategy to alleviate global water scarcity. However, the trade‐off between high salt loading and structural stability in AWH sorbent materials remains a critical bottleneck. Here, we report a hierarchical composite gel (D‐HKPB@LiCl) that …

Abstract. Vapor pressure deficit (VPD) is increasingly recognized as the primary driver of uncertainty in future global evapotranspiration (E) trends. Accurately characterizing the spatiotemporal dynamics of VPD and clarifying its mechanisms of influence on terrestrial E are crucial for improving water-use efficiency, …

Inverse design of incoherent multiple image differentiation with spatial multiplexing optical convolution

Feng Hua Huang, Guofeng Zhu, Hewen Wang, Byongyong Yi et autres

Optical edge detection has shown attractive research interests in target recognition and machine vision, due to the low computational power, parallel operation, and high speed. However, the incoherent optical imaging systems are linear with respect to light intensity; thus, it is nearly …

Terraced fields increased soil organic carbon content in croplands of the loess plateau

Qinqin Wang, Yuanxiao Xu, Guofeng Zhu, Yinying Jiao et autres

Terracing is widely distributed in mountainous and hilly areas worldwide to increase grain production, control soil erosion, increase soil moisture, and improve soil quality, potentially impacting soil carbon pools. This study investigates how agricultural activities and ecological restoration measures affect soil carbon …
