Abstract

Abstract: Fractional vegetation coverage (FVC) and leaf area index (LAI) are the key parameters of ecological environment, and their remote sensing monitoring of dynamic changes are of great significance to reveal the evolution law of land ecological environment and scientific supervision of ecological environment.Based on the fractional vegetation coverage and leaf area index data of GLASS products from 2000 to 2016, this paper monitored the spatiotemporal dynamic changes of FVC and LAI in Fangcheng Golden Camellia National Nature Reserve in Guangxi.The results show that:the FVC and LAI of the reserve were relatively high from 2000 to 2016, and the changes of FVC and LAI showed an increasing trend the overall spatial distribution of the reserve was that the eastern region was better than the western region. From 2000 to 2016, the annual average FVC and annual average LAI of the protected areas increased by 7.48% and 28.47%, respectively. The lowest value and peak value of the annual average FVC of the reserve were in 2004 and 2016, respectively, and their values were 0.711 and 0.833. The lowest value and peak value of the annual average LAI of the reserve were in 2000 and 2016, respectively, and their values were 3.425 and 4.400.

Key words: fractional vegetation coverage, leaf area index, golden camellia reserve, spatiotemporal dynamic changes, remote sensing monitoring
