In this paper the concept and content of the pressure-sate-response (PSR) model were discussed. The PSR model combined with analytical hierarchy process (AHP) is employed to establish a assessment system for mangrove ecosystem health. Based on a comprehensive health index (CHI) value, the health of mangrove ecosystems can be divided into three states: excellent, healthy and sub-healthy. The assessing system achieves visualization by Microsoft Visual Basic (VB). Combined with the actual findings of the mangrove, the visual assessing system is verified. The CHI of the mangrove of Gaoqiao Town in Zhanjiang City of Guangdong Province is 80.54. The CHI of the mangrove of Qiao Island of Zhuhai City in Guangdong Province is 60.35. The CHI of the mangrove of Techeng Island of Zhanjiang City in Guangdong Province is 53.87. The results are consistent with the investigation. The visualization system will be used scientifically, rapidly and practically with the health assessing for the mangrove ecosystem.
