Abstract: The purpose is to apply GIS technology to construct a forest park landscape ecology assessment system, and guide the planning and development of forest parks. Through the analysis of the landscape influence factors of Zhaogaoguan Forest Park, the native landscape, visual sensitivity, landscape suitability degree, and health degree were selected as evaluation indicators to construct a forest ecological assessment index system. By using factor superposition method and AHP, combined with GIS technology, we analyzed the weight of each evaluation index, established a forest park landscape ecology evaluation system, and conducted an ecological evaluation of Zhaogaoguan Forest Park. The results showed that the index weight was 0.3971 for the suitability degree, 0.2726 for the visual sensitivity, 0.1232 for the original degree, and 0.2071 for the health degree. The highest value of landscape ecological assessment data of Zhaogaoguan Forest Park was 3.0655, the lowest value was 1.2071, and the overall landscape ecological condition was good. Based on the results of the landscape ecological assessment of Zhaogaoguan Forest Park, the corresponding protected areas are divided according to the actual condition of the park, and the human activities in each area are controlled to varying degrees, and countermeasures are proposed for the development of the park. Based on the evaluation and zoning, we put forward an optimized strategy for park planning, aiming at the transformation of the planning from a traditional extensive model to a scientific and ecological model.
