摘　　要：Spatio-temporal database manages the large amount of spatial objects that change over time. It is necessary to query the spatio-temporal objects of the past and the current and to anticipate the future of spatio-temporal objects. It Is important to design an efficient index mechanism for accessing the spatio-temporal data efficiently. The paper analyzes the features of the spatio-temporal objects, studies the methods of spatio-temporal index mechanisms, classifies the index mechanisms, and discusses the key technologies of spatio-temporal indexes. And it also presents the index methods of STADBS that we are studying.Spatio-temporal database manages the large amount of spatial objects that change over time.
