Response of Runoff in High Altitude Area over the Typical Chinese Monsoonal Temperate Glacial Region to Climate Warming

Based on the the hydrological and meteorological data in Lijiang basin, the precipitation, groundwater and runoff in this typical monsoonal temperate glacier area increase significantly, which suggests that water cycle over the region more rapidly under the climate warming. The increase amplitude of runoff in the downstream region of the glaciated area is much stronger than that of precipitation, resulting from the prominent increase of melt water from Mt. Yulong. It indicates that the contribution made by melt water to runoff increase is great under the climate warming, especially in autumn, winter and spring. It is also obvious in Hailuogou basin according to the preliminary analysis of the observational hydrological and meteorological data. The results in this paper are significant to study the glacier variation, water balance and glacier disaster in Chinese monsoonal temperate glacier regions.
