英文摘要	Biophysical parameters such as albedo, normalized difference vegetation index (NDVI), land surface temperature (LST) and rainfall etc. are indicators of eco-environments. In this paper, monthly and yearly average albedos, NDVI and LST are retrieved using NOAA/AVHRR images over 1981-2000. Then, eco-environmental monitoring indices are established based on those parameters with the combination of rainfall data which are obtained from China Meteorological Administration (CMA). Considering regional features of Chinese coastal zone, which is chosen as the study area, we selected typical 20 points (each point covers 8x8km area) from north to south latitude. Yearly average value of abovementioned bio-physical parameters are calculated and gathered over each point. At last, dynamics and degradation problems during last two decades in the Chinese coastal zone eco-environments are explored.; Geosciences, Multidisciplinary; Remote Sensing; CPCI-S(ISTP); 0
