Other Abstract



Quantitative evaluation on the vegetation recovery after the earthquake is of great scientific significance for local ecological system rebuilding and regional social-economic sustainable development. By taking the Longxi River Basin in Dujiangyan of Sichuan Province as an example,and employing the MODIS-NDVI time-series data,this paper illustrated the dynamic changes of the vegetation cover rates in Longxi River basin before and after the“5.12”Wenchuan Earthquake by using Landsat data,and then time-space characters of the recovery rates of the damaged vegetation was quantified structurally by referring the factors of river-system and terrain. The results showed that the recovery of impaired vegetation coverage worked well from a holistic point of view,but the response of vegetation coverage to earthquake disaster showed a lagging-phenomenon. The recovery rate of damaged vegetation was significantly correlated to its distance to surrounding river systems, elevation,slope degree,and slope aspect. This finding could provide technical supports for decision-makers to intervene the recovering process after earthquake.
