Variation in Ecosystem Service Value in Response to Landscape Pattern Changes of Zhujiajian Island, China

G. Shen, X. Wang, D. Wang, and X. Xia
Abstract—Sea islands are fundamental components of marine and coastal ecosystems among the most productive in terms of services that are linked to human well-being. The landscape patterns of sea islands are undergoing considerable changes from natural successions and anthropogenic activities, which affect their ecosystem service value (ESV), ultimately resulting in ecosystem degradation. Landscape patterns for Zhujiajian Island were derived for seven periods from 1986 to 2014 using Landsat 5 TM and Landsat 8 OLI data by an unsupervised K-Means method. Based on the quantitative relationship between individual landscape type and corresponding ESV, the paper introduced two indexes: total ecosystem service value (TESV) and mean ecosystem service value (MESV). These indexes were used to interpret the ecological implications of landscape pattern changes affecting sea-island ecosystems. Although the area increased by 5%, the TESV of Zhujiajian Island continuously declined by 21% from 1986 to 2014, which suggested ineffective environmental protection and management paralleling social and economic development. The MESV declined dramatically by 25% in the study period, indicating a marked degradation of the ecosystem quality of Zhujiajian Island. The results suggest that human activities should be sustainably managed to prevent the ecosystem degradation of Zhujiajian Island.

Index Terms—Ecosystem service value, landscape pattern, Zhujiajian Island, variation.
