Simulating responses of riparian ecosystem network complexity to flow regime shifts in arid regions by Mengmeng Zhang, Chengyi Zhao, Jianting Zhu, Wangya Han, Wenqi Jiang

“…This study applied a modified community-wide population model, integrated with network theory, to simulate the responses of the riparian ecosystem to potential future flow regimes in a desert oasis in northwestern China. Results indicate that the riparian ecosystem network in the desert oasis is inherently unstable under the Heihe River’s current hydrological conditions, characterized by considerable intra-annual and inter-annual runoff variability, as even minor changes in flow regimes could alter the network. …”

Ground-Based Polarimetric Remote Sensing of Dust Aerosol Properties in Chinese Deserts near Hexi Corridor by Hua Xu, Zhengqiang Li, Donghui Li, Li Li, Xingfeng Chen, Yisong Xie, Kaitao Li, Cheng Chen, Yuhuan Zhang

“…One-year observation of dust aerosol properties near Hexi Corridor was obtained from polarimetric measurements by ground-based sunphotometer in the county of Minqin in northwestern China from March 2012 to February 2013. We observed an annual mean AOD of 0.22±0.22 at 0.50 μm and Ångström exponents of 0.1–1.0 fitting a bimode normal distribution centered at 0.18 and 0.50, respectively. …”
