Biodiversity simulation of Poyang Lake wetlands by using InVEST model under different scenarios

Assessment of ecosystem services are more and more applied in natural resource management. In this paper, we applied the FoPIA approch to build different land use/land cover scenarios in Poyang Lake wetlands by 2020. Then, we used the scenario parameters and land use/land cover indexes as input into the Integrated Valuation of Ecosystem Services and Tradeoffs model (InVEST). InVEST has been used to assess a typical village’s habitat quality of migratory birds which is the biodiversity index of species in Poyang Lake wetlands. Results showed that: under the conversation scenario, the scale of habitat quality of migratory birds will be increased and the threat of human activities will be decreased obviously, influenced by ecological engineering, all these will making the average of habitat quality of the migratory birds in the typical village of Poyang Lake wetlands reach 0.89, showing an increase of 27.0%. Under the economic developing scenarios, human activities will be expanded and some of the superior quality habitat will be occupied by agriculture lands, therefore, the average habitat quality will decrease to 0.57, showing a decline of 14.0%. Under the nature developing scenarios, human activities will not change so much, and the average habitat quality is 0.66, showing an increase of 1.5%.
