Abstract


With the intensification of the impact of human activities in northern China river runoff was more obvious attenuation , while the southern humid areas relatively rich river runoff , although in recent years the scale of human activities increased , but the overall situation of the river runoff changes less significantly , so there is little to carry out human activities affect the analysis of the situation of the southern region of river runoff , especially in the area of Guangdong Province, with abundant precipitation , research in this area is almost close to the blank . Exacerbated by human activities , water resources situation of the Regions in Guangdong Province has also undergone some changes , have become increasingly prominent contradiction between supply and demand of water , the water quality of the environment contamination , especially in the river downstream of the region grim situation of water shortage in the dry season , so the evolution of water resources The situation has aroused widespread concern . Collect the basic information and references existing relevant research results on the basis of a comprehensive and objective evaluation of the water resources of Guangdong Province , and for the first time to study the evolution of the situation of water resources in Guangdong Province . Based on precipitation and runoff of major rivers in Guangdong Province, a long series of data , analysis of precipitation, evaporation change and human activities on the evolution of the law of Guangdong Province, surface runoff situation . Focus on analysis of the past 20 years , due to the impact of human activities lead to temporal and spatial variations in the quantity and quality of water resources situation, using qualitative and quantitative method of combining the water resources situation caused by natural conditions ( precipitation ) and human activities change characteristics and laws of research and analysis, further detailed understanding of the evolution of the situation of water resources in Guangdong Province , rational understanding of water resources , to analyze its problems , in order to take appropriate and timely measures and measures . In this paper, mathematical statistics , such as the moving average method , power spectrum , wavelet analysis and maximum entropy method to analyze the changes in precipitation and runoff trends and Wet and Dry periodic variation , a comprehensive reflection of Guangdong Province, the inter-annual variation of precipitation and runoff .
