摘要:

在核算黄河流域生态系统服务供给、需求及供需均衡度的基础上,分析国土空间格局演变与供需均衡度时空变化的共变趋势,采用相关分析和分位数回归方法测度各类国土空间对均衡度的影响及区域异质性。结果表明:(1)黄河流域国土空间格局及生态系统服务供需时空差异明显。下游和中上游沿河县域生活生产用地密集分布且2000—2015年增幅明显,生态系统服务供给增加与耕地和林地的分布一致,需求增加与人口密度和建设用地分布一致。(2)均衡度的时空变异受到国土空间格局演变的影响。不同均衡度水平下国土空间对均衡度的影响程度不同,且区域差异显著。(3)根据对均衡度产生影响的国土空间不同,不同区域应合理布局用地和发展政策以促进生态系统有效管理。

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.
