ABSTRACT
Hainan Tropical Rainforest National Park (HTNP) and its surrounding areas face the dual
challenges of ecological fragmentation and environmental degradation, yet few studies have
quantitatively integrated Ecological Environment Quality (EEQ) and Landscape Ecological Risk
(LER) to guide spatial governance. This study aims to construct a multi-level Ecological Security
Pattern (ESP) that integrates EEQ and LER, providing a scientific basis for balancing conservation
and development. Using multi-source remote sensing data from 2002 to 2022, GIS spatial analysis, and
the Least Cumulative Resistance (LCR) model, we identified ecological source areas, corridors, and
buffer zones, and validated connectivity through Ecological Risk Index (ERI) and patch aggregation
indices. Results indicate a pronounced distance-decay gradient and corridors in the ERI. The 2022 ERI
increased from 0.149 at 2,500 m to 0.163 at 10,000 m, whereas the 12 ecological corridor networks
significantly enhanced landscape connectivity in the park’s peripheral areas. The core area maintained
high ecological integrity and stability, while coastal zones still exhibited high-risk fragmentation
clusters associated with human expansion. Accordingly, integrating EEQ and LER coupling into ESP
construction can effectively enhance ecological resilience and provide decision-making support for
adaptive spatial governance of HTNP.
