- 摘要:
- 为了解孟加拉国博多河流域植被生长特征及其与气候因子的关联程度,研究以Landsat影像为数据源提取1980年、2000年、2017年博多河流域归一化植被指数(NDVI),利用GIS的空间分析方法结合数学统计方法,分析了流域NDVI的变化特征和变化趋势,并用Pearson相关系数对NDVI与气候因子之间的相关关系进行了探讨。结果表明:(1)1980年、2000年流域NDVI以裸露区为主,2017年以低覆盖区为主,近40年NDVI空间分布状况呈东部、南部高,西部、北部低的分布模式;(2)流域NDVI在1980—2000年呈下降趋势,在2000—2017年呈上升趋势,近40年流域植被状况显著好转;(3)1980—2017年博多河流域年总降雨量逐年递增,年平均温度先减少后增加且整体呈增加趋势;(4)流域NDVI对降雨量的变化更为敏感,其中降雨量对流域的干旱地区NDVI的影响显著,而温度对流域降雨量较高地区的NDVI影响显著。研究结果不仅可为博多河流域植被的增加和生态环境的修复提供参考,而且可为中国“一带一路”区域发展在生态方面的建设提供理论依据。
- Abstract:
- In order to understand the characteristics of vegetation growth in the Padma River Basin of Bangladesh and its relationship with climate change, the Landsat data was used as data sources to extract normalized difference vegetation index(NDVI)of Padma River Basin of Bangladesh in 1980, 2000 and 2017. And we analyzed the characteristics and the trends of NDVI of Padma River Basin by using the spatial analysis method of GIS and mathematical statistical method. Finally, Pearson correlation coefficient was used to analyze the correlation between NDVI and climatic factors. The results showed that:(1)NDVI was dominated by the bare areas in 1980 and 2000, and it was dominated by the low coverage areas in 2017; the distribution of NDVI in the past 40 years was high in the east and south, and it was low in the west and north;(2)the change of NDVI showed a downward trend from 1980 to 2000, and it was on the rise from 2000 to 2017; the vegetation situation in Padma River Basin had improved significantly in the past 40 years;(3)from 1980 to 2017, the annual total rainfall of Padma River Basin increased year by year; the annual average temperature decreased first and then increased, and the general trend was rising;(4)the effect of rainfall on NDVI was higher than temperature overall, the impact of rainfall on NDVI was more pronounced in arid areas of the basin, and the effect of temperature on NDVI was more pronounced in areas with higher rainfall. These results not only provide references for the increase of vegetation in Padma River Basin and the restoration of ecological environment, but also provide a theoretical basis for the ecological development of Chinese regional development of the Belt and Road.
