Abstract
Through soil samples collecting and analysis in Hebei plain, we studied acidity characteristics and acidification sensitivity in Hebei plain. Results showed that the main reasons for decline in soil pH value is the atmospheric acid deposition, the excessive application of nitrogen and phosphorus fertilizer, crop base ion absorption. The dissolve of calcium carbonate is the main process plain cushion soil acidification in Hebei plain, its content is the decisive factor of soil acidification sensitivity.
