摘要：利用2014年至2020年期间携带背负式卫星跟踪器的21只白鹤(Grus leucogranus)的定位数据,识别出了被跟踪白鹤所有的重要中途停歇地;采用监督分类的方法,利用2014年、2015年和2020年的Landsat 8 OLI影像数据,获取了土地利用信息,通过量化指标和转移矩阵,对识别出的白鹤重要中途停歇地的各土地利用类型的动态进行了分析。研究结果表明,在白鹤迁徙路线上,共识别出187处中途停歇地,其中,108处中途停歇地在中国境内,79处中途停歇地在俄罗斯萨哈共和国;根据13只白鹤的完整迁徙路线,共识别出25处白鹤重要中途停歇地,其中,11处在俄罗斯萨哈共和国,14处在中国境内;首次发现的国内白鹤重要中途停歇地有6处,分别是黑龙江省杜尔伯特蒙古族自治县的连环湖、内蒙古自治区科尔沁右翼中旗的珠日很淖尔湖和敖汉旗的乌兰乌苏水库、安徽省和江苏省交界处的石臼湖、安徽省六安市的淠河中游、湖北省蕲春县的蕲水;与2015年相比,2020年,中国的白鹤重要中途停歇地的土地利用格局发生了明显变化,以耕地在扩张、草地(包括草本沼泽)和湖泊在萎缩为特征,白鹤的栖息空间在缩小,生境质量在变差。
This paper uses the positioning data of 21 satellite-tracked Siberian Cranes(Grus leucogeranus) from^(2)014 to 2020 to identify all the important stopover sites for Siberian Cranes. Using Landsat 8 OLI remote sensing images in 2014, 2015 and 2020, the land use information of the important stopover sites for Siberian Cranesof was extracted by the method of supervised classification, and the dynamic of the land use patterns was analysized using quantitative indicators and transition matrix for the purpose to analyze the land use pattern changes of the important stopover sites of those tracked Siberian Cranes in China. The results showed that 187 stopover sites were identified in the migratory routes of the tracked Siberian Cranes,including 11 important stopover sites in the other country and 14 important stopover sites in China. The 6 important stopover sites in China were discovered for the first time, they were Lianhuan Lake of Durbert Mongolian Autonomous county, Heilongjiang province, Zhurihennaur Lake of Horqin Right Wing Middle Banner and Wulanwusu Reservoir in Mutouyingzi Township, Aohan Banner in Inner Mongolia Autonomous Region, Shijiu Lake at the junction of Anhui and Jiangsu provinces, middle reaches of Pihe River of Luan city,Anhui province, and Qishui of Qichun county, Hubei province. Compared with those in 2015, the land use patterns of the important stopover sites for Siberian Cranes changed significantly in China in 2020, the areas of cultivated lands expanded significantly, and the areas of grasslands and lakes decreased, the areas of reservoirs and ponds increased, and the areas of the habitat suitabled for Siberian Crane has decreased obviously.
