【Abstract】 Conversion of natural habitats from forest to agricultural and industrial landscape and then to degraded land is a major factor resulting in reduced biodiversity. Species with different functional traits strongly affect on structure and function of ecosystem. Low biodiversity characterizes the degraded ecosystems which bring great concern in the world. The emerging of restoration ecology provides tool and opportunity to reverse the trend of losing species. Therefore, whether a degraded ecosystem could be recovered or not depends on the recovery of its biodiversity.更多还原
