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.

To assess the spatial and temporal changes in land use/cover and landscape in Liushahe watershed,relief maps published in 1965 were digitized,and three Landsat MSS/TM/ETM images from 1976,1988 and 2003 were classified by Erdas Imagine then converted to shape format based on Arc View,and rest of the analyses were performed in GIS environments based polices and traditional nation customs.

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.
