文摘内容 Studying the response to warming of hydrological systems in China’s temperate glacier region is essential in order to provide information required for sustainable development.The results indicated the warming climate has had an impact on the hydrological cycle.As the glacier area subject to melting has increased and the ablation season has become longer,the contribution of meltwater to annual river discharge has increased.The earlier onset of ablation at higher elevation glaciers has resulted in the period of minimum discharge occurring earlier in the year.Seasonal runoff variations are dominated by snow and glacier melt,and an increase of meltwater has resulted in changes of the annual water cycle in the Lijiang Basin and Hailuogou Basin.The increase amplitude of runoff in the downstream region of the glacial area is much stronger than that of precipitation,resulting from the prominent increase of meltwater from glacier region in two basins.Continued observations in the glacierized basins should be undertaken in order to monitor changes,to reveal the relationships between climate,glaciers,hydrology and water supplies,and to assist in maintaining sustainable regional development.
