Abstract:

The Yellow River Basin plays an important role in social economic development and ecological security. Based on the remote sensing interpretation data of 2000,2005,2010,2015 and 2020 and the economic and social statistical data, we calculated the aquatic ecosystem service value of 71 cities (states and leagues) in 9 provinces of the Yellow River Basin, analyzed the time-space coordination between aquatic ecosystem services and economic development by constructing the consistency index. The consistent index of ecosystem services and economy was developed to explore their spatio-temporal coordination characteristics. The results show that: (1) From 2000 to 2020, the area of the Yellow River Basin increased year by year, in which the area of the upper reaches increases the most and increased by a big margin, and the area of the lower reaches increased larger and increased by a maximum margin, while the area of the middle reaches decreased slightly and decreased by a Minor margin. The area of reservoirs, canals, lakes, permanent glaciers and snow land increased, and the area of beach land and tidal flat decreased. (2) During the study period, the increase of the aquatic ecosystem service value in the Yellow River basin gradually slowed down, and the increase of ecosystem service value in the lower reaches was the largest, followed by the upper reaches and the lowest in the middle reaches. In 2015-2020, there was even a decline in Shaanxi, Shanxi and the whole middle reaches. (3) The discordance between ecosystem services and economic development in the Yellow River basin is obvious, and the economic agglomeration is higher than the ecosystem services agglomeration, and this situation keeps for a long time. In the upper reaches of space, the concentration of ecosystem services is higher than that of economy, and in the middle and lower reaches and provincial capitals, the concentration of economy is higher than that of ecosystem services.
