A Comparative Study On The Habitats Of The White Spoonbill(Platalea Leucorodia)in Different Periods

From June 2016 to April 2017,radio tracking technology was used to locate,track,and field survey of the White Spoonbill which bred in Heilongjiang Taihu National Wetland Park in order to collect data of different kinds of habitats of the White Spoonbill in different periods(breeding period,migration period,wintering period).We selected Heilongjiang Taihu National Wetland Park(propagation period),Jilin moon bubble,Shandong Yantai,Shandong Rushan(migrating period)and Jiangsu Gaoyou Lake(wintering period)to investigation and SPSS(23)software is used to compare and analyze these seven main factors:vegetation density,advantageous planting height,vegetation coverage,food abundance,water depth,water transparency,and distance of human interference in different periods.The type of wetland where the White Spoonbill migrated to stopover was mainly reed marshes,as well as shallow water areas of reservoirs,lakes,and rivers.The stopover sites of the White Spoonbill are rich in food,and the vegetation is mostly reed and lush.The dominant species of vegetation is 49.4?204.3 cm in height and the vegetation coverage is more than 50%.The water area accounts for 50%to 100%of the area of the stopover area,the quality of water is good,the depth is 10?30cm,and the transparency is about 10?30cm.The artificial disturbance distance of the white spoonbill habitat is 90?300m,but the level of human interference is low.The principal component analysis of habitat habitat in SPSS(23)software showed that the requirements of the environment for the White Spoonbill during the breeding period,the migration period and the wintering period are slightly different.The most important factors in the breeding period were vegetation height and food abundance and the principal component contribution rate was 49.892%.The main influencing factors of stopover sites were vegetation type,food abundance,and water transparency,the principal component contribution rate was 35.617%.The main influencing factors of wintering ground were human disturbance,food abundance and vegetation coverage,and the main component contribution rate was 40.051%.Ihe requirements for habitat factors are approximately the same in different stopover sites,and the main influence factor is food abundance.Based on a comprehensive analysis of the live stopover sites,the breeding site had the highest comprehensive score of 31.882%,which was the most suitable habitat for the White Spoonbill,followed by the wintering ground,which was 27.541%,and the rest of the three stopover sites had poorer habitat conditions,which is 16.646.%,indicating that the most critical condition for the selection of habitat for the White Spoonbill is the growth and development site of the young bird,followed by the selection of the wintering ground,and the habitat conditions of the stopover site can be appropriately relaxed.The resting time of the White Spoonbill in stopover sites are highest in terms of vegetation coverage,food abundance,and dominant species height,and have low correlation with distance to the human disturbance.
