Abstract

By integrating multiple remote sensing data sources this study accurately assesses the spatiotemporal characteristics of changes in ecosystem service values (ESVs) in the Yellow River Basin from 2000 to 2015 through Theil-Sen median trend analysis and the Mann-Kendall test. The stability and continuity of the ESVs were comprehensively characterized using coefficients of variation and the Hurst exponent. The degree of coherence between ESVs and economic growth (represented by gross domestic product GDP) on the same temporal and spatial scales was analyzed using ecological-economic coordination (EEC) models. The results show that (1) from 2001 to 2015 the total ESV and the ESV per unit area in the Yellow River Basin generally showed a U-shaped pattern (decreasing slightly then increasing rapidly). (2) The areas with increasing ESVs made up approximately 55.6% of the total area of the river basin. The areas with a decreasing pattern were mainly in the west and north of the Yellow River Basin. (3) The stability and continuity of the ESVs showed a clustered, compact distribution. (4) The most common level of EEC was slightly uncoordinated followed by slightly coordinated and highly coordinated. The proportion of coordinated areas was relatively higher in cultivated land and the lowest in built-up land.

摘要

本研究通过 Theil-Sen 中位数趋势分析和 Mann-Kendall 检验,整合了多源遥感数据,准确评估了 2000-2015 年黄河流域生态系统服务价值(ESV)的时空变化特征。通过变异系数和赫斯特指数综合描述了 ESV 的稳定性和连续性。利用生态经济协调(EEC)模型,分析了 ESV 与同一时空尺度下经济增长(以国内生产总值 GDP 表示)之间的一致性程度。结果表明:(1)2001-2015 年,黄河流域的总 ESV 和单位面积 ESV 总体呈 U 型模式(先略有下降,然后迅速上升)。(2)ESV 增加的区域约占流域总面积的 55.6%。呈下降趋势的区域主要集中在黄河流域的西部和北部。(3)ESV 的稳定性和连续性呈集聚、紧凑的分布。(4)最常见的 EEC 水平是轻度不协调,其次是轻度协调和高度协调。协调区的比例在耕地中相对较高,在建设用地中最低。
