Temporal and spatial evolution of habitat quality in Fujian and Taiwan coastal zones based on land use change and its influencing factors
Under the background of rapid urbanization and industrialization,it is of great significance to assess the quality of coastal zone habitat and reveal the key driving factors affecting habitat change for sustainable development of coastal zone ecology.This study took the east coast of Fujian and the West coast of Taiwan(hereinafter referred to as the Fujian and Taiwan coastal zones)as the research objects.With the help of the land use and socio-economic data in 1990,2000,2010 and 2020,the InVEST model and geographic detector were used to analyze the spatio-temporal evolution characteristics and influencing factors of habitat quality under land use change.It provides a reliable theoretical basis for urban ecological space optimization.The results show that:(1)The main characteristics of land use change between 1990 and 2020 are the increase of construction land and the decrease of cultivated land.The area of construction land increased the most from 2000 to 2010,with an average annual growth of 5.66%.Arable land,as the largest source of construction land,decreased by 1 781 km²,an average annual decrease of 2.55%.The east coast of Fujian is larger than the west coast of Taiwan.(2)From 1990 to 2020,the average habitat quality of the coastal zone in Fujian and Taiwan was 0.82,and the overall ecological quality was good,but showed a downward trend.From 2000 to 2010,the area of low-grade habitat on both sides of the strait increased the fastest,and the growth rate slowed down after 2010.The transfer of ecological land to non-ecological land contributed more than 70%to habitat degradation.(3)Night light index,population density,GDP,elevation and slope were the main factors affecting habitat quality,and the dominant factors changed from topographic factors to socio-economic factors in the past 30 years.The research provides scientific basis for land and sea land resource management in coastal areas of Fujian and Taiwan,and is of great significance for regional collaborative development.
