The diversity of trophic structure and process is one of the most important aspects of ecosystem diversity.In the present paper, the macroscopic trophic structures of ecosystems are analyzed by the methodology of macroscopic trophic dynamics,and two indexes revealing the diversity of ecosystem trophic structure are defined.The diversity indexes of ecosystem trophic structure are the distribution diversity of standing stocks and flows along the macroscopic trophic chain(DⅠ),and the distribution diversity of standing stocks and flows in all compartments(DⅡ).The indexes of diversity are two fundemantal measures to reflect the diversity of trophic structure in an ecosystem.
