摘　　要：淮河流域是我国重要的粮食生产基地,研究其生态环境变化具有重要意义。针对目前对淮河流域生态环境缺乏充分研究的问题,通过构建改进的遥感生态指数(MRSEI),对淮河流域2000—2022年生态环境质量时空变化进行了评价和分析。结果表明:①2000—2022年,淮河流域MRSEI先降后升,其中2000—2010年缓慢下降,2012—2022年逐渐升高。②MRSEI变化趋势的显著水平较低,显著降低的区域集中在淮河流域西北部,显著升高的区域集中在淮河流域北部和南部。③重标极差(R/S)分析结果表明,淮河流域未来生态环境变化以反持久性为主,58.1%的像元未来会表现为恶化,31.1%的像元未来会表现为改善,平均持续时长为4.2年。④未来趋势变化的莫兰指数为0.828,说明未来趋势变化的空间分布呈聚集态。⑤地表温度是淮河流域生态环境变化的主导因素,植被覆盖、干度、湿度影响力次之,高程、风速、降雨量、蒸发量和相对湿度的影响力较小。研究结果可为淮河流域生态环境治理提供依据。Huaihe River Basin is an important grain production base in China,and studying its ecological environment changes is of great significance.In view of the lack of ecological environment research in the Huaihe River Basin,the spatial and temporal changes of ecological environment quality in the Huaihe River Basin from 2000 to 2022 were evaluated and analyzed by constructing an modified remote sensing ecological index(MRSEI).The results showed that:①The MRSEI index of the Huaihe River Basin first decreased and then increased.It slowly declined from 2000 to 2010 and gradually rose from 2012 to 2022.②The significant level of MRSEI change trend was low.Areas with a significantly decrease were concentrated in the northwest of the Huaihe River Basin,while areas with a significant increase were concentrated in the northern and southern parts.③According to the results of the R/S analysis,the future ecological environment change is mainly anti-persistent,58.1%of the pixels will deteriorate and 31.1%of the pixels will improve in the future,with an average duration of 4.2 years.④The Moran index of future trend change was 0.828,indicating that the spatial distribution of future trend change is clustered.⑤Temperature is the leading factor affecting environmental changes,followed by vegetation cover,aridity,and humidity.The influence of elevation,wind speed,precipitation,evaporation,and relative humidity is minimal.This study provides a basis for the environmental management of the Huaihe River Basin.
