A Theme-Based and Network Coupled Framework for Quantatitive Indicators Selection in Ecological Construction: A Case Study in Fujian, China

It is important to build a scientific and effective indicator system for the assessment and management of regional ecological construction. A theme-based and network coupled framework provides a useful approach to solve some problems in establishing indicator systems, such as lack of systematic study on indicators connotation and non-transparent processes of indicators selection. Based on the ecological construction practice in Fujian province, China, this paper (1) analyzed the main challenges of the ecological construction,implementation and development processes, summarized the currently main themes for ecological construction, and built a theme-based indicators framework; (2) established indicators selection criteria matrix and alternative indicators matrix by using network analysis method; (3) built a multi-objective selection model considering the economic cost, social effect and ecological integrity by genetic algorithm to quantitatively select operational indicators of ecological construction. Our study will contribute to deeply understanding the connotation and improving the science and validity of the ecological indicators system for ecological construction assessment and management applications.
