Temporal and Spatial Changes of Ecosystem Health in Guangdong Province in Recent 11 Years

摘要

As a coastal province in southern China, the economy of Guangdong has been rapidly developed after the implementation of the reform and opening up. In the past decades, the authority of Guangdong has emphasized ecological health construction while paying attention to economic development. Meanwhile, the construction of "the Belt and Road Initiatives" has posed great challenges to the health of the local ecosystem. Based on the Vigour -Organization-Resilience Model (VOR), the ecological health assessment system was established to evaluate and analyze the ecosystem health from 2009 to 2019 of Guangdong. Results showed that the ecosystem health of Guangdong showed a slight improvement for the study period, The areas with greater than level 2 had decreased by 8.42%. The overall ecological system health varied from general to good. The ecosystem health of the study area exhibited obvious spatial heterogeneity. The level of the ecosystem health in the northern part was better than the southern part. The ecosystem health of the study area decreased slightly at the beginning and then increased significantly, and the ecosystem health showed a stable and positive trend.
