Abstract: An experiment was conducted to analyze and evaluate the spatial-temporal dynamic changes of forest ecological benefits in water conservation,soil conservation,carbon fixation and air purification in Yanqing county of Beijing based on forest management inventory data of 1999 and 2004.The results showed that this area achieved remarkable ecological benefits with a large increase during the 5 years.The increase of runoff,soil erosion decrement,biomass,SO2 absorption and dust suppression reached 24.11%,19.37%,10.06%,30.77% and 33.79% respectively.Meanwhile the spatial distribution also became more balanced with the scope being extended.

Key words: forest resources, forest management inventory data, ecological benefit, spatial-temporal dynamic
