Abstract
Binzhou Shell Islands and Wetland National Nature Reserve is one of the three ancient shell ridges in the world,which is the most completely conserved and the only old and new coexis-tence.Based on the RS and GIS technology,and many times of field survey in 2015,using the sat-ellite remote sensing data of 1979,1990,2000,2008 and 2015,the change characteristics data of Binzhou Shell Islands and Wetland National Nature Reserve in nearly 40 years were obtained.Theresults showed that:(1)The total area of Binzhou shell ridges is 28.86 hm2 in 2015,which is 0.07% of the total area of the study area,mainly distributs in the core area along the northern coast of the study area.(2)In 1979—2015,the area of Binzhou shell ridges overall trend has been reduced,particularly in 2008—2015 shell ridges area has been drastically reduced.The main reason of the reduction of shell ridges'area is the development and utilization of human activity,among which,agricultural land,salt fields and farms are the most important factors.(3)Human activity remote sensing inspection system was established to improve relevant laws and regulations,and to repair the habitat of shell ridges,which is an effective countermeasure against the shell ridges'en-croachment and destruction.关键词
