Evaluation of the impacts of human activities on propagation from meteorological drought to hydrological drought in the Weihe River Basin, China.

Understanding the relationship among different types of drought is crucial for drought mitigation and early warnings. Much attention has been recently focused on the propagation from meteorological drought (MD) to hydrological drought (HD); however, the influences of human activities on drought propagation have rarely been explored. The novelty of the study was to propose an effective framework to quantify the impacts of human activities on MD-HD propagation.

Spatio-temporal pattern of ecological droughts and their impacts on health of vegetation in Northwestern China.

The ecological implications of drought have been widely discussed in recent years. Ecological drought was thus proposed as a new drought type to describe the impact of drought on ecosystems. The current study used an innovative drought index, called the standardized ecological water deficit index (SEWDI), to monitor terrestrial ecological drought in Northwestern China, which is an ecologically fragile region.

Comprehensive Evaluation on Soil Properties and Growth under Combined Application of Fly Ash and Polyacrylamide in North China.

A field experiment was conducted to investigate the combined application effects of fly ash (FA) (0, 5%, 10%, and 15% (/) soil) and polyacrylamide (PAM) (0, 0.006% and 0.012% (/) soil) on the edge of Hobq Desert in Inner Mongolia, China from May 2016 to October 2018.

Application of Entropy Spectral Method for Streamflow Forecasting in Northwest China.

Streamflow forecasting is vital for reservoir operation, flood control, power generation, river ecological restoration, irrigation and navigation. Although monthly streamflow time series are statistic, they also exhibit seasonal and periodic patterns. Using maximum Burg entropy, maximum configurational entropy and minimum relative entropy, the forecasting models for monthly streamflow series were constructed for five hydrological stations in northwest China.
