Soil and water conservation of reservoir watershed and its water yield:A case study of Chaobaihe River Basin on the upper reaches of Miyun Reservoir;

Chaobaihe river basin is one of the main water sources in Beijing.

Impacts of Precipitation Changes and Human Activities on Annual Runoff of Chao River Basin During Past 45 years;

A Research on Distributed Time Variant Gain Model: a Case Study on Chaohe River Basin;

Study on Mesh Scale of TOPMODEL for Chaohe River Basin;

The Chaohe River basin,which accounts for 31% of the area of upper Miyun Reservoir catchment,was selected as the study area.

Based on the landscape pattern of Baihe watershed in 2000 and atmosphere and runoff from 1990 to 2007 and the sediment and water quality from year 2001 to 2006, sensitive parameter have been analysised and calibrated and verified.

Application of VIC Land Surface Hydrological Model in Flow Simulation of Bailian River Basin;

Both models are applied to the Bailian River basin in Hubei Province to discuss their adaptability in flow simulation of the medium or small basin and their effects are compared.

The model was applied in Bailian River basin in Hubei Province to discuss its adaptability in flow simulation of the medium or small basin.

Taking the Baisha river which was the first level tributaries of the Tianquan river as the study object, the impact to landscape elements, landscape structure and landscape function of the small hydropower rundle development in Baisha river drainage area were analyzed by the numbers in this study.
