Review on researches of water conservation forests.

Water conservation forest is a special kind of protection forests. It does not only have normal ecological, economic and social benefits, but also can protect water resources, accommodate runoff, cut down floods, control soil erosion and purify water quality. Thus, specialists began to pay more attention to water conservation forests with research method of forest hydrology since 1980s.
