  • Seasonal characters of regional vegetation activity in response to climate change in West China in recent 20 years
  • AVHRR ; Biogeography ; China ; Climatic change ; Climatic warming ; NOAA ; Remote sensing ; Seasonal variability ; Vegetation ; Vegetation index
  • The emphasis of the research is to analyze the spatial-temporal character of vegetation change and the correlation with climate change, according to vegetation evolvement of West China from 1982 to 2000. Using NDVI data of NOAA-AVHRR
  • and the temperature and precipitation data of West China, the vegetation activity is discussed by adopting the EOF and REOF decomposed functions.

  • Impact of climate variation on fog in China
  • China ; Climate ; Climatic data ; Climatic trend ; Climatic variability ; Fog ; Global change ; Moisture ; Temperature
  • Using foggy days and mean temperature and relative humidity data of 602 stations from January to December in the period 1961-2003 in China, the relationship between variations of foggy days and temperature and its possible reason for the 43 years
  • were analyzed by regression, correlation and contrastive analysis methods. The results induce a decrease in relative humidity when the climate becomes warmer, and eventually brings about a decrease in foggy days in China.

  • Soil losses due to potato and sugar beet harvesting in NE China
  • Agricultural technique ; Agropedology ; China ; Crop ; North-Eastern China ; Potato ; Sediment budget ; Soil erosion ; Soil properties ; Sugar beet
  • This study investigated soil loss due to crop harvesting (SLCH) for potato and sugar beet plots on farmer's fields spread over 4 regions in northeast China where harvesting is carried out by hand. The aims are to evaluate the impacts of possible
  • determining factors, such as soil texture and soil moisture content at harvesting time, on SLCH variability; to estimate the relative importance of SLCH for the total sediment budget in northeast China; to compare 2 harvesting techniques, by hand

  • Spatial and temporal variations and controlling factors of potential evapotranspiration in China : 1956-2000
  • Annual variation ; China ; Evapotranspiration ; Potential evapotranspiration ; Seasonal variation ; Solar radiation ; Spatial variation ; Water cycle ; Wind speed
  • Based on the climatic data of 580 stations in China during 1956 and 2000, potential evapotranspiration are calculated using the Penman-Monteith Method. The spatial and temporal distributions of the potential evapotranspiration over China
  • and the temporal trends of the regional means for 10 major river basins and whole China are analyzed. Through a partial correlation analysis, the major climate factors which affect the temporal change of the potential evapotranspiration are analyzed. Decline

  • 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.
