The Optimization Strategy of Resources Utilization System of National Parks: Taking the Bawangling Zone of the Hainan Tropical Rainforest National Park as an Example

National parks with Chinese characteristics are the highest-level nature reserve, and their establishment marks the strictest means of ecological protection. The establishment of resources utilization system of National Parks under the new era and new protection policies is of great value in breaking the "ecological protection only" misunderstanding and exploring how to carry out sustainable utilization of resources in the reform of national park system. Based on the analytic hierarchy process and the Delphi method, combined with the establishment requirements of the new nature reserve system and the total value of resource ecosystem services (harvest value, existence value and future value), this study determines the framework, reference standards, weights and indicators for forest resources utilization assessment. Based on the case study of the Bawangling zone of the Hainan Tropical Rainforest National Park, the future optimal resources utilization system under the national park system is proposed, and two system optimization strategies are pointed out, i.e., ecological adjustment of resources utilization system and establishment of appropriate resources utilization system.
