- Abstract:

Ha-Chang urban agglomeration ranks first in the national second-tier city group. Studying the changes of ecosystem services and weighing the synergy between the Ha-Chang urban agglomeration areas is of far-reaching significance to promote the sustainable development of the region. Based on multi-source remote sensing data combined with InVEST model and trade-off synergy model(ESTD), we analyzed the land cover changes in 2000, 2010 and 2015 of Ha-Chang urban agglomeration, the spatial-temporal distribution of three ecosystem services, soil conservation, carbon storage and water production, and their tradeoff synergy relationship. The results show that:(1)from 2000 to 2015, the total construction land in the Ha-Chang urban agglomeration increased by 1 462 km2; among them, the growth rate from 2000 to 2010(958 km2)was higher than that from 2010 to 2015(504 km2); in the past 15 years, the forest land increased by 1 527 km2, and the grassland, cultivated land and bare land decreased by 661 km2,1 611 km2 and 780 km2, respectively;(2)in the past 15 years, the amount of soil conservation continued to decrease, the carbon storage decreased first and then increased, and the water yield increased first and then decreased;(3)among the six types of land cover, the forest land provided the highest soil conservation capacity per unit area, and the wetland provided the highest carbon storage and water yield;(4)synergism was dominant among the three ecosystem services of Ha-Chang urban agglomeration; the soil conservation-carbon storage and soil conservation-water production in the south were mostly synergistic, on the contrary in the North, from the whole area, the correlation between carbon storage-water production was relatively weak. The results can provide the reference for the development of more comprehensive and specific ecological protection strategies in the Ha-Chang urban agglomeration area.
