Gravitational wave standard sirens can be used to arbitrate the $H_0$ tensionwithin the following several years. In the future, the observation ofgravitational wave standard sirens would be developed into a powerful newcosmological probe because they can play an important role in breakingparameter degeneracies formed by other observations. Therefore, gravitationalwave standard sirens are of great importance for the future accuratemeasurement of cosmological parameters.
