Abstract According to the problems of landscape ecological method application in planning environmental impact assessment (PEIA), such as assessment methods are insufficient, index system is imperfect or lack of combination with planning optimization, an evaluation index system comprised of landscape structure, landscape function and landscape intimidation was constructed with comprehensive consideration of socioeconomic factors. And accordingly the landscape ecological impact of the planning was evaluated. Meanwhile, computer model was introduced to simulate the dynamic landscape pattern of the alternatives. By analyzing the changes of landscape metrics, comparison and selection for alternatives was achieved. Based on above results, the application framework for landscape ecological method in PEIA was established and then applied in PEIA of Dalian forest park. Results showed that the plan improved the landscape patter and function, but it also increased landscape disturbance. Trend of landscape fragmentation was significant under alternative 1, and landscape developed an intensive integration trend under alternative 2.
