The reference and recent working results about ecology of ash (Fraxinus mandshurica) were reviewed, which including: distribution range, suitable site, phonology, growth, photosynthesis, productivity, natural regeneration effect and mixture effect. Synthesizing above, it was suggest that the ecological characters of ash such as distribution range, limited factors, growth site etc., as well as its biology characters, features in forest, should be considered as an important basis to develop this species by different regeneration ways such as natural regeneration, artificial regeneration and natural regeneration by man-help. And experiment in artificial regeneration showed that the mixture of ash with larch has benefit to being free from or alleviating frost injury and enhancing growth
