摘要

[目的] 为研究植被对不同时间尺度干旱的响应机理

明确西南地区极端干旱事件频发对植被生长产生严重的负面影响。[方法] 基于西南地区2001—2019年的NPP数据和1~24个月连续尺度的SPEI数据

采用相关分析法、最大值合成法及显著性检验等方法探究西南地区不同地貌类型植被NPP对多尺度SPEI的响应特征

并分析不同植被类型NPP对多尺度SPEI响应的差异性。[结果] (1)在年际、季节及生长季尺度

植被NPP与1~24个月尺度SPEI的响应均以1－3月尺度占主导

表明植被NPP对短期干旱变化具有较好的响应

不同地貌分区响应时间表现出差异性。(2)空间上

植被NPP与1~24个月尺度SPEI的最大相关系数呈明显的异质性和季节性差异。年际相关性表现出从东南—西北呈显著正相关—显著负相关的变化趋势

季节相关性表现为夏季均以显著负相关占主导

春季、秋季和冬季均以显著正相关占主导

表明西南地区的夏季温度高且湿润

使植被生长受限

生长季正、负相关关系的区域面积比例相差不大

且呈显著正相关面积最大的地区为广西丘陵

呈显著负相关面积最大的地区为若尔盖高原。(3)不同植被类型NPP对1~24个月尺度SPEI的响应具有一定差异

尽管草地、灌丛、林地对SPEI的响应特征基本相似

但所有植被类型NPP在夏季随SPEI尺度的缩短呈负相关趋势越强烈。表明在夏季高温干旱条件下

各种植被类型都更易受到干旱的影响。[结论] 研究结果为西南地区生态系统的保护和修复提供有效的科学支撑

同时

为防灾减灾及应对气候变化提供重要的理论依据

有助于制定更具针对性的政策和措施

推动西南地区的可持续发展。

Abstract

[Objective] This study was aimed to explore the response mechanism of vegetation to drought at different times scales and clarify the frequent occurrence of extreme drought events in southwest China on vegetation growth. [Methods] Based on vegetation net primary productivity (NPP) data from 2001 to 2019 and standardized precipitation evapotranspiration index (SPEI) data on a continuous scale from 1-24 months in southwest China

correlation analysis

maximum synthesis method

significance test were used to analyze the responses of NPP of different geomorphic types and vegetation types to multi-scale SPEI in southwest China. [Results] (1) On the annual scale

seasonal scale and growing season

the responses of vegetation NPP and SPEI at 1-24 months were dominated by the January-March scale

vegetation NPP had a good response to short-term drought changes

but a relatively poor response to medium and long-term drought changes. (2) The response of NPP to SPEI at 1-24 month scale showed significant spatial heterogeneity and seasonal differences. The interannual correlation showed a trend of significant positive correlation to significant negative correlation from southeast to northwest. The seasonal correlation showed that significant negative correlation was dominant in summer

significant positive correlation was dominant in spring

autumn

and winter. This indicated that in the southwest China

the summer temperature was high and humid

which limited vegetation growth the area with the largest positive correlation was Guangxi Hills

while the area with the largest negative correlation was Zoige Plateau. (3) The responses of NPP to SPEI from 1-24 months were different among different vegetation types. Although the response characteristics of grassland

scrub and forest land to SPEI were basically similar

the trend of negative correlation between NPP and SPEI became stronger with the scales of SPEI decreased in summer for all types of vegetation. This suggested that all types of vegetation are more susceptible to drought under high temperature and drought conditions in summer. [Conclusion] The research results provide effective scientific support for the protection and restoration of the ecosystem in the southwest China

provide an important theoretical basis for disaster prevention and reduction and coping with climate change

help formulate more targeted policies and measures to promote the sustainable development of southwest China.
