Based on the observation data of lake water level from 1961 to 2012, using time series linear trend analysis and wavelet analysis, comparative study Bosten Lake and Issyk-Kul nearly 50 years water level change characteristics and predictive analysis the lake water level future trends. The results show that: ①from 1961 to 2012, Bosten Lake and Issyk-Kul annual water level shows a significant decline trend. Before the mid-1980s, the two lakes water level almost the same change trend, all steady decline. After the 1990s, Bosten Lake water level change fluctuation more frequent than the Issyk-Kul, has experienced rapid rise and fall stages, but the Issyk-Kul water level is relatively stable. ②wavelet analysis results show that, Bosten Lake and Issyk-Kul annual water level presence 18-a and 22-a primary period. According to the water level future change trend forecast results, In future for a period of time Bosten Lake water level continued to decline, Issyk-Kul lake water level continued to rise.
Key words: Bosten Lake; Issyk-Kul Lake; water level; wavelet analysis; comparative analysis
