Study on Eco-Safety Early-Warning and Assessment Index System of Hainan Province

To have a comprehensive evaluation on the safety of regional ecology, research is required within the fields of eco-safety and early warning on all relevant elements that affect the ecological environment of a given region. This should be complemented by research on influential elements based on regional characteristics and then followed by the construction of an eco-safety early-warning assessment index system. This article analyzes research findings of related ecological assessments and eco-safety problems of Hainan province in particular. With a focus on economic construction and sustainabe development, this analysis reflects on economic, social, environmental, technological, and institutional factors and proposes an eco-safety early-warning assessment index system which suits Hainan's ecological situation. This index system synthesizes Hainan's natural resources, ecological situation, degree of pollution, and economic development and consists of five first-class indicators (low-carbon society, land resource safety, water resource safety, air resource safety, and biological species safety), ten second-class indicators (economy, society, environmental resources, technology, low carbon, system, arable land safety, forest safety, land pollution, etc.) and 90 third-class indicators.
