Abstract:

Based on the calculation of the ecosystem service supply, demand and coordination degree in the Yellow River Basin, we comprehensively analyzed the co-variation trend of land spatial pattern and coordination degree of supply-demand in this basin. Then, correlation analysis and quantile regression were used to analyze the influence of various land spaces on the coordination degree of supply-demand, and its regional heterogeneity. The results showed that: (1) Land spatial pattern, and supply and demand of ecosystem services showed significant spatio-temporal differentiation. The upper and middle reaches of the river and the lower reach are areas with densely distributed and significantly increased productive land and living land from 2000 to 2015. The increase in supply of ecosystem service was consistent with the distribution of cultivated land and forest land, and that in demand of ecosystem service was consistent with the distribution of population density and construction land. (2) The spatio-temporal change of the coordination degree was affected by the evolution of land spatial pattern. The influence of the land spaces on the coordination degree of supply and demand was different under different coordination levels, and there was significant regional heterogeneity in different regions. (3) According to different land spaces that had an impact on the coordination degree, different areas should rationally lay out land space and formulate development policies to promote effective ecosystem management.

Key words: land spatial pattern, ecosystem services of supply and demand, coordination degree, spatio-temporal variation, Yellow River Basin
