| 摘 要： | 植被覆盖度（FVC）和叶面积指数（LAI）作为关键生态环境参数，其时空动态变化的遥感监测对揭示陆地生态环境演变规律与科学监管生态环境具有重要意义。本文基于2000-2016年GLASS产品的植被覆盖度和叶面积指数数据，对广西防城金花茶国家级自然保护区FVC和LAI的时空动态变化进行监测。研究结果表明：①2000-2016年保护区的FVC和LAI较高，FVC和LAI的变化呈增长的趋势，空间分布整体情况是东部区域好于西部区域；②2000-2016年保护区年均FVC和年均LAI分别增长了7.48%、28.47%；③保护区年均FVC的最低值和峰值分别是在2004年和2016年，其值分别为0.711、0.833，保护区年均LAI的最低值和峰值分别是在2000年和2016年，其值分别为3.425、4.400。

| 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. |
