[Objective] This paper studid the optimization of protecting the ecological land in a rational way in order to provide a scientific solution to the conflict between urban expansion and natural environment.[Methods] Fuzhou City was selected as the study area, this paper extracted the core ecological land through ecological importance comprehensive evaluation, then ecological land conservation zone was identified by utilizing the methodology of ecological security patterns. The conservation zone scheme was collated with the ecological protection red line which is currently administrated by the department of environment.[Results] The land cover type of the core ecological land in Fuzhou City was predominantly consist of forest and water area, and its spatial distribution emerged as a coast-inland pattern. In comparision with the ecological protection red line, the ecological land conservation zone had the advantage in the degree of landscape fragmentation and aggregation, and also with a better overall landscape connectivity.[Conclusion] Ecosystem services and ecological process would be more abundant and effective under the scenario of ecological land conservation zone. The method and conclusion from this example could not only supplement the technological process of the ecological protection red line but also improve its practicality, which is an efficient way of optimizing the ecological land protection and achieving government's goal.
