摘要

长江流域作为关键的生态安全屏障,深入理解其生长季NDVI对气候变化的响应,对于长江流域生态环境保护策略的有效实施至关重要.本文利用2000~2020年MODIS NDVI数据以及同期气象数据,运用趋势分析法、偏相关分析等方法并结合GIS空间统计分析等方法,探讨了长江流域生长季NDVI对昼夜温度及降水的响应特征.结果表明:2000~2020年长江流域生长季NDVI整体呈波动增加趋势,增速为0.021/10a;除太湖流域外,其他子流域NDVI均呈极显著增加趋势.NDVI呈增加趋势的面积占比为84.19%,太湖流域超过60%的区域呈减少趋势,其余子流域以增加趋势为主.生长季Tmax、Tmin和降水量均呈不显著上升趋势,Tmin的增加速率约为Tmax的1.55倍,昼夜增温速率表现出不对称性,除金沙江流域外,其他子流域与研究区变化趋势相似.空间上,生长季Tmax、Tmin和降水量呈增加趋势的区域占比为68%~79%,以太湖和乌江流域增加趋势最为明显.生长季NDVI对Tmax、Tmin和降水量的响应表现出一定空间异质性,植被生长受Tmin和降水量显著影响的范围较Tmax更广泛.生长季NDVI对Tmin、降水量和Tmax的平均滞后响应时间分别为1.3个月、1.4个月和1.6个月;不同子流域及不同植被类型NDVI对Tmax、Tmin和降水量的响应有一定差异.

Abstract

The Yangtze River Basin is an important ecological barrier in China. Understanding the response of the NDVI to climate change during the growing season is important for the effective implementation of ecological and environmental protection strategies. In this study, on the basis of MODIS NDVI data and meteorological data from 2000 to 2020, the response of the NDVI to diurnal temperature and precipitation changes during the growing season was studied through trend analysis, partial correlation analysis and GIS spatial statistical analysis methods. The results revealed the following: from 2000~2020, the growing season NDVI exhibited a fluctuating increasing trend in the Yangtze River Basin, with a growth rate of 0.021/10a. The NDVI exhibited an increasing trend in all subbasins except for Taihu Lake. The overall NDVI exhibited an increasing trend, accounting for 84.19% of the study area, and all subbasins exhibited increasing trends, with the exception of the Taihu Basin, which showed a decreasing trend (60%). (2) During the growing season, Tmax, Tmin and precipitation showed insignificant upward trends, and the increase rate of Tmin was approximately 1.55 times that of Tmax, indicating asymmetric diurnal warming. At the subbasin scale, the change trend was similar to that in the study area except for the Jinsha River Basin. Spatially, Tmax, Tmin and precipitation showed increasing trends, with proportions ranging from 68% to 79%, especially in the Taihu and Wujiang River Basins. The responses of the NDVI to Tmax, Tmin and precipitation during the growing season exhibited spatial heterogeneity, and the range of vegetation growth significantly affected by Tmin and precipitation was greater than that affected by Tmax. The average lag times of the responses of the NDVI to Tmax, Tmin and precipitation during the growing season were 1.6, 1.3 and 1.4 months, respectively. The response characteristics differed across subbasins and vegetation types.
