Landscape Pa ttern and Function Ana lysis for theWa ter ResourcesConserva tion Forests of the Gongbiela RiverWa tershed by GIS

This study focused on increasing the water resource conservation ability of the Gongbiela riverwatershed.By GIS techonology and available advanced high spatial resolution remote sensing image SPOT5, the landscape image database was set up. According to the analyse of the spational distribution and the composing of the forest typesand forest species, The p roblem existing in the water resources conservation forests were pointed out. And all thiswas p rovided to quantificationally analyse the ability of water resource conservation and to meet the demands of theregional forestry engineering construction, constructing the forest system with coverage rate feasible, structure rational and the ecologieal benefits.
