| 摘 要： | 以遥感、地理信息系统和全球定位系统为主，应用空间对地观测的技术资源和数据资源，结合地面考察资料和已有的研究成果，对环青海湖地区的湿地类型和面积变化进行研究，结果发现：研究区内的湿地分为天然湿地和人工湿地两大类，其中天然湿地分为沼泽、河流、湖泊。天然湿地的面积在13 a内出现了不同程度的变化，其中沼泽面积有所扩大，而河流、湖泊面积缩小。造成这种变化的主要原因是气候暖干化和人类活动的共同影响。 |

| Abstract: | Supported by remote sensing,geographical information system and global positioning system,and by the technology of observing to the ground on space and using the data,and combining with the ground inspection material and the former research results,this article studied the change of the wetland type and the area in Qinghai Lake region.The results indicated that the wetland in the research area could be divided into two kinds: the natural wetland and the artificial wetland,and the former could be divided into the marsh,the river,the lake.The area of the natural wetland appeared various degree changes in 13 years: the area of the marsh expanded,but that of the river and the lake reduced.The main reason that resulted in the above was the influence of climate warming and drying,and the humanity activities. |
