| Abstract: | This study focused on increasing the water resource conservation ability of the Gongbiela fiver watershed. By GIS techonology and available advanced high spatial resolution remote sensing image SPOTS, the landscape image database was set up. According to the analyse of the spational distribution and the composing of the forest types and forest species, The problem existing in the water resources conservation forests were pointed out. And all this was provided to quantificationally analyse the ability of water resource conservation and to meet the demands of the regional forestry engineering construction, constructing the forest system with coverage rate feasible, structure rational and the ecological benefits. |
