Abstract: After entering the anthropocene, the human agency has been recognized as a kind of geological force. The abiotic and biotic factors of ecosystem have been changed irreversibly because of environmental changes, introduction of invasive species and land abandonment, caused by deliberate or inadvertent human activities. These changes have generated novel ecosystems. The concept of novel ecosystems has been followed with great interest by experts in the field of ecological conservation and ecosystem restoration. This paper introduced the background of novel ecosystems, which includes the concept, formation mechanism, and other related knowledge. Then we introduced the concept of novel urban ecosystems proposed by Jack Ahren, that is recognizing ecosystem services/disservices as metrics to evaluate the contributions of projects to sustainable development and leading to adaptive design. This can provide guidance for the development of landscape architecture in the field of ecosystem restoration. Here are the two main guidance: 1) We need to rethink the traditional methods of ecosystem restoration aiming at restoring to the state in the history. 2) We can achieve the common goal of sustainable development by taking ecosystem services/disservices as metrics to evaluate ecosystem and promoting interdisciplinary collaboration. Absolutely the premise is to recognize the existence of novel ecosystems and promise to adjust the direction of management to ecosystem restoration.
