Spatial-temporal evolution and prediction of coastal landscape pattern and habitat quality based on MCE-CA-Markov and In VEST model
Under the background of rapid urbanization,this paper analyzed the temporal and spatial dis-tribution changes of landscape pattern and habitat quality in Nanhui Dongtan coastal zone of Shanghai,so as to provide a theoretical basis for ecological environment protection and policy planning in the coastal zone.Based on the land use data of Nanhui Dongtan coastal zone interpreted by remote sensing in the years of 2013,2015,2017 and 2019,the landscape pattern of Nanhui Dongtan coastal zone in 2021 and 2023 was predicted by MCE-CA-Markov model combined with the actual environment,and the spatio-temporal evolution characteristics of habitat quality in the study area from 2013 to 2023 were analyzed by InVEST model.From 2013 to 2019,the main landscape types in the study area were con-struction land and tidal flat.The area of sea water,forest land and cultivated land decreased year by year.The part of cultivated land decreased was mainly transformed into construction land,and the area of sea water decreased was mainly transformed into tidal flat.The index of habitat quality in the study area decreased year by year,and the overall habitat quality decreased,and a large number of high habi-tat areas in the east changed to medium habitat.From 2019 to 2023,the landscape pattern and habitat quality of Nanhui Dongtan coastal zone continued to maintain the change trend from 2013 to 2019,mainly reflected in the increase of construction land area and the decline of habitat quality.The main reason for the decline of habitat quality and the change of landscape pattern in the study area was the e-conomic activities of human society,in which the development of urbanization was an important factor in the landscape ecological change of Nanhui Dongtan coastal zone.
