  • Based on China's monthly precipitation data of 629 stations during 1950-2000, the AA. calculate Z indices and separate them into 7 Dryness and Wetness grades. Further, a drought area index is proposed to study changes in drought severity in northern
  • China. The results reveal that the different seveity of droughts all showed expanding trends in northern China's main agricultural area. Moreover, the area coverage of droughts in different seasons and different regions display different trends.
  • Dust storm erosion and its impact on soil carbon and nitrogen losses in northern China
  • Agricultural practice ; Arid area ; Carbon ; China ; Dust storm ; Nitrogen ; Northern China ; Nutrient ; Soil conservation ; Soil erosion ; Wind erosion
  • This paper reviews the recent literature concerning dust storm-related soil erosion and its impact on soil C and N losses in northern China. The purpose of this study is to provide an overview of the area of erosion-affected soils and to estimate
  • the magnitude of soil C and N losses from farmland affected by dust storm erosion. The results indicate that soil conservation measures along with improved soil fertility management measures should be promoted in dry-land farming areas of northern China.
  • Preliminary study of Quaternary tectono-climatic cycles in China in Quaternary glaciations in the Northern Hemisphere.
  • Stratigraphy and paléoenvironmental changes in the loess of central China in Quaternary glaciations in the Northern Hemisphere.

  • The AA. examined the spatial distribution of the continent coastline in northern China using remote sensing and GIS techniques, and calculated the fractal dimension of the coastline by box-counting method, with a time span from 2000 to 2012
  • . Moreover, they analyzed the characteristics of spatial-temporal changes in the coastline's length and fractal dimension, the relationship between the length change and fractal dimension change, and the driving forces of coastline changes in northern China
  • will, in most cases, lead to the increase (or decrease) of the whole coastline fractal dimension. Civil-coastal engineering construction was the most important factor driving the coastline change in northern China. Compared to human activities, the influence
