Abstract:

Aims: The purpose of establishing national parks in China is to protect the integrity and authenticity of natural ecosystems and to promote biodiversity conservation. Evaluation of the integrity and authenticity of national parks is a prerequisite for studies such as layout planning, boundary range determination, and functional zoning of national parks. To assess the integrity and authenticity status of natural ecosystems in national parks, this study provided a method in which data are easily accessible, assessment methods are simpler, and assessment results are clearly understood by decision-makers, managers, and the public.
Methods: Based on the structure and function of terrestrial natural ecosystems, this study constructed an evaluation index system of terrestrial natural ecosystem integrity and authenticity and its quantitative evaluation method through index screening, expert consultation, index quantification, and the establishment of a comprehensive evaluation model. The evaluation method contained five indicators of natural ecosystem integrity, five indicators of natural ecosystem authenticity, and two comprehensive evaluation indicators. Taking Qianjiangyuan National Park system pilot in Zhejiang Province as an example, this study initially assessed its ecosystem integrity and authenticity status, and graded the assessment results.
Results: According to the assessment method of this study, the evaluation result of natural ecosystem integrity of Qianjiangyuan National Park system pilot was 52.83%, with a less good evaluation grade; while the evaluation result of natural ecosystem authenticity was 87.06%, with a good evaluation grade. The indicators that deserve attention and improvement in Qianjiangyuan National Park system pilot include the integrity index of the conservation area (27.00%) and the integrity index of the flagship species suitable habitat (53.04%).
Conclusion: This study constructed an evaluation method for the integrity and authenticity of terrestrial natural ecosystems in national parks with comprehensive evaluation index coverage, easy data acquisition, and easy evaluation results to be understood by decision makers and managers.
