最近30年来人类活动对莱州湾南岸地貌过程及海水入侵的影响
INFLUENCES OF HUMAN ACTIVITIES ON THE COASTAL LANDFORM AND SEA WATER INVASION ALONG THE SOUTHERN LAIZHOU BAY DURING THE PAST 30 YEARS
摘要
Abstract
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. Meanwhile, owing to the conversion from natural types to artificial types of geomorphology, or the increasing human activities in this region, the coastal landform has turned from siltation to erosion. Therefore, the distribution areas of surface sea water or brine are increased, resulting in the constant movement of brackish water to land. Reasonable human interference is the fundamental approach to improve the coastal ecology environment of the Laizhou bay.关键词
