摘要
为探究1990—2020年黄河流域森林覆盖时空变化及其驱动因素,本文基于土地覆盖、自然因素及人类活动数据,使用转移矩阵、Theil-Sen Median和Manna-Kendall趋势分析、地理探测器进行了研究。结果表明:①黄河流域森林覆盖范围扩大,覆盖面积增加近2万km 2;②1990—2020年,黄河流域168个县的森林覆盖率呈增长趋势,仅两个县的森林覆盖率减少;③基于地理探测器的结果表明,短波辐射对森林覆盖分布解释力最大,交互探测表明,降雨和高程的交互作用对森林覆盖分布解释力最强。本文可为黄河流域生态环境高质量发展提供科学参考。
To investigate the spatio-temporal changes and driving factors of forest coverage from 1990 to 2020 in the Yellow River Basin,this study employs land use and land cover data,natural factors,and human activity data,and uses transfer matrix,Theil-Sen Median and Manna-Kendall trend analysis,and geographic detectors for research.The results show that:①The forest coverage area has expanded in the Yellow River basin,with an increase of nearly 20000 km 2.②From 1990 to 2020,the forest coverage rate of 168 counties increased in the Yellow River basin,with only two counties showing a decrease in forest coverage.③Based on geographic detectors,shortwave radiation has the greatest explanatory power for the distribution of forest coverage,while the interaction of rainfall and elevation has the strongest explanatory power in the analysis of factor interaction.This study can provide a scientific reference for the high-quality development of the ecological environment in the Yellow River basin.
