Abstract: The resource pressure brought by rapid urbanization challenges the urban ecosystems, and maintaining urban ecosystem security is very important for both urban eco-environmental health and urban high-quality sustainable development. This study reviews the progress in the ecosystem security evaluation methods and the related directions. We classify the urban ecosystem security evaluation models into 12 types, and delineate their advantages, disadvantages and applicability. The urban ecosystem security evaluation indicators are classified into 7 types including biology, water, atmosphere, land, society, economy and population. Among these, a total of 33 commonly used evaluation indicators are selected for suggestions for future studies. We also analyze the substantial effect of each indicator on urban ecosystem security. Finally, we propose several potential directions for future research on urban ecosystem security.

Key words: urban ecosystem security, analysis of current situation, evaluation model, evaluation indicator, future directions
