Ecological Classification of Forest Landscape in Beijing Miyun Reservoir Water Catchment

The forest landscape in Beijing Miyun reservoir water catchment is ecologically classified based on remote sensing images and digital topographical maps and by using ARC View and Fragstats.Some data from forest field survey and GPS locations are also used in this work.The forest landscape in this research area can be divided into two forest landscape kinds or three landscape series or six landscape groups or five landscape types or nine landscape sub-types.The ecological type forest landscape is the dominant one in this area.Most of the forest landscape is covered with young forest and open forest.The proportion of mixed forest is relatively low.The area of each landscape patch is mostly fragmental with regular shape,which means a heavy human disturbance occurred in the forest landscape.Therefore,the forest management should aim at water resource reserving and soil and water conservation.And some work as to forest tending and diverified practices of planting mixed forest should be strengthened.
