摘要
Taking the four-phase MSS/TM remote sensing images since 1979 as the main source of information, this paper extracts geomorphologic information in different times along the southern Laizhou bay through visual interpretation. The analysis of the effects of human activities on the coastal geomorphologic process and sea water intrusion was conducted with the methods of RS, GIS and landscape ecology on the basis of field geomorphologic investigation. The results show that the diversity index and evenness index of the overall coastal geomorphology were in a pattern of rising first and dropping later, indicating the increase and decrease in the heterogeneity of the coastal geomorphology.
