Taking Daling forest farm as an example,this paper analyzed the spatial-temporal change of forest resources using TM in 1999 and ETM+ in 2006 as main data source,and survey data as assisted.The results showed that the farmland and open forest land decreased,and broad-leaved forest land,coniferous forest land,mixed forest land and shrub land increased during the period 1999-2006,indicating natural forest protection project benefiting the regeneration of natural forest resource and the sustainable development of forest farm.The biggest changes occur in open forest land,and followed by shrub land,broad-leaved forest land,mingled forest land,farm land and coniferous forest land.关键词
