Remote Sensing Analysis of Fractional Vegetation Cover Change Triggered by Island Construction
Translated Abstract
The original ecological environment of island is fragile and lack of stability. Large-scale development and construction activities of island expose the vulnerable vegetation to a greater danger, which makes the detec-tion and assessment of vegetation cover change especially necessary. Based on the remote sensing images of Landsat 5 and Landsat 8 in 2001, 2010 and 2014, the fractional vegetation cover (FVC) of Pingtan Island in Fuji-an Province was computed using the FVC calculation model proposed by Gutmand and Ignatov. Combining the FVC data with land cover change information, this study analyzed the variation in FVC of integrated experimen-tal zone on Pingtan Island and explored its reason. The results showed that in 2001, 2010 and 2014, the middle and upper level of FVC in Pingtan Island accounted for 86.00%, 58.92%, 71.16%, respectively, which indicate that the overall vegetation in the study area is in good condition. The analysis of dynamic change showed that there is a declining trend in FVC from 2001 to 2014. The FVC decreased greatly by 53.95%from 2001 to 2010. On the contrast, the FVC rose by 47.77%from 2010 to 2014, which improved overall FVC condition substantial-ly and offset the previously significant decrease of FVC. The comprehensive experimentation area was estab-lished in Pingtan Island. Greening projects and reasonable planning gradually improved the vegetation construc-tion and protection of the island green land system. These reasons led to the increase of vegetation.
