Based on the literature published at home and abroad before, this paper analyzed the ecological service value of the forest management on different time and spatial scale. As the development of the forest planning system, the systems will develop more and more complicated for forest function trade-off analysis. The forest planning studio developed more and more popular for the forest management study institution. The forest planning system including the multi-function models, forest grow and harvest models, and the stand spatial structure modified models. As the climate changing, the scale of landscape became more and more popular and useful on forest assessment by multi-scale and database.
