摘  要:
This paper summarized the eco-geographical law of the elm woodlands, and discussed preliminarily significance and ecological role in maintaining the biodiversity of temperate grassland eco-regions. The opininon was put forwards which the way to substitute the elm woodlands with artificial forests was worth deliberating. It was proposed that the values of the woodlands in protecting the biodiversity of temperate grassland eco-regions should be thought highly of and studied, and some high-ranking nature reserves should be set up.
