| 摘 要： | 为探究生态系统服务间的权衡/协同关系,以对区域可持续发展提供决策参考。在分析和模拟土地利用变化的基础上,对武汉城市圈39个区县的食物供给服务、碳储量服务和生境质量服务进行了评估,探究其时空演变特征和权衡/协同关系。结果表明:(1)武汉城市圈2005—2018年建设用地和水域面积不断增加,而耕地、林地、草地和未利用地持续减少。2035年综合发展情景下耕地减少趋势得到缓解,林地面积有所增加,建设用地实现有序扩张。(2)武汉城市圈食物供给服务持续提高,碳储量服务不断下降,生境质量总体上也呈下降趋势。多重服务重要区识别表明,各年份中度重要区域面积最大,而极其重要区域面积最小。(3)相关系数法和双变量空间自相关法均表明多尺度下不同情景的生态系统服务间权衡/协同关系是一致的,但程度有所区别。由此可得,区域3种生态系统服务间以权衡关系为主,且不同情景下权衡/协同关系的程度不同。

| Abstract: | To explore the trade-off/synergy between ecosystem services to provide decision-making reference for regional sustainable development, based on the analysis and simulation of land use change, the food supply service, carbon storage service and habitat quality service of 39 districts and counties in Wuhan city circle were evaluated to explore their temporal and spatial evolution characteristics and trade-off/synergy. The results show that:(1)from 2005 to 2018, the construction land and water area of Wuhan City circle continued to increase, while the cultivated land, forestland, grassland and unused land continued to decrease; under the comprehensive development scenario in 2035, the decreasing trend of cultivated land will be alleviated, the area of forestland will increase, and the construction land will expand orderly;(2)the food supply service in Wuhan City circle continues to improve, the carbon storage service continues to decline, and the habitat quality also shows a downward trend on the whole; the identification of multiple service important areas shows that the area of moderately important areas is the largest and the area of extremely important areas is the smallest in each year;(3)both correlation coefficient method and bivariate spatial autocorrelation method show that the trade-off/synergy relationship between ecosystem services in different scenarios is consistent at multiple scales, but the degree is different. It can be seen that the trade-off relationship is dominant among the three ecosystem services in the region, and the degree of trade-off/synergy relationships are different in different scenarios. |
