Land use change impacts on heavy metal sedimentation in mangrove wetlands - A case study in Dongzhai Harbor of Hainan, China

Abstract

When human activities change land use patterns, many environment elements are being changed accordingly. Well understanding the links between various changes could help to achieve ecological protection through adjusting land use pattern. Mangrove is one of the most valuable ecosystems that have been changed dramatically during the recent decades. Based on Remote Sensing and Geography Information System, along with soil sample determination, we present a quantitative study about the correlations between land use changes and the variations in heavy metal contents in mangrove soil sediments of DongZhai Harbor in China. The results showed that the indices depicting the landscape pattern characte..
