Landscape Pattern Change and Its Driving Forces in Liaoning Coastal Areas
摘要
Abstract
Landscape pattern change is not only the basic core research extent in landscape ecology,but also a hotspot in the field of the global environmental change.In this paper,the landscape types of the coastal areas in Liaoning Province were classified using Landsat5 TM data in 1998 and Landsat8 OLI/TIRS data in 2013 with the support of Remote Sensing (RS) and Geographic Information System (GIS) and the changes inlandscape patterns and the driving force factors were analyzed based on 10 landscape metrics.The results showed that:during last 15 years,the total area of coastal areas in Liaoning had a slight trend of expansion;meantime a large spatial transformation occured between various land use types,in other words,the spatial pat-tern of landscape changed significantly.The landscape dominance decreased and the diversity increased.It was caused by the main driving forces of natural geography condition,population increase,economic development and government policy that induced the regional discrepancy and changes of landscape patterns in Liaoning coastal areas.The coastal area is located between terrestrial ecosystem and marine ecosystem,and its ecological environment is vulnerable.Goverment policies and economic development promote Liaoning' s opening to the outside world,which affects the landscape pattern in this area.Thus,people should improve their ecological pro-tection consciousness and focus on strengthening ecological protection and management of coastal areas in Lia-oning Province.关键词
