Abstract: In this paper,the genesis,evolutionary tendency and spatial temporal distribution of flood and water logging in Dongting Lake area were discussed.Based on analysis of historical data,the occurrence of flood and water logging disasters was divided into four different phases.In view of the causes of disaster formation,the author brought up the comprehensive countermeasures for flood and water logging control in Dongting Lake area.

Key words: soil organic carbon, wavelet transform, multi-scale correlation, partial correlation coefficient,  mountainous area of Guangdong Province.
