| Abstract: | Based on the precipitation data observed from meteorological stations in Suibin,Fuyuan and Tongjiang of eastern Sanjiang plain from 1967 to 2008,the precipitation characteristics in the past 50 years were analyzed by linear regression analyses,M-K test and wavelet analysis.And the drought-flood,laws were analyzed by compared between the standard precipitation index and the precipitation anomaly in the last 50 years.The results showed that： 1.Precipitation in the region declined for many years,the largest decline to 20mm/10a.2.Spring drought and summer flood are the main meteorological disasters that influence local agricultural production.In recent years,the frequency of drought was increasing,impact spring quality,crop growth,yield and quality of agricultural products. |
| Keywords: | drought-flood laws precipitation Sanjiang plain comparative analysis |
