| 中文摘要 | The wetlands in the middle and lower reaches of the Tarim River are a rich area of biodiversity and natural resources in the inland arid region of China. However, this wetland area has decreased in size during the past several decades. Water quality and biodiversity has declined due to expanded agricultural activities since 1960s. Using remote sensing (RS), geographic information system (GIS) and global positioning system (GPS) techniques, we investigated the dynamics, spatial patterns and fragmentation of the wetlands in the middle and lower reaches of the Tarim River from 1980 to 2000. We found that the total area of the wetlands was reduced by 45.8% and the density of the patches increased four times from 1980 to 1990. From 1990 to 2000, though the total area of the wetlands slightly increased the number of the patches increased three times and the density of the patches doubled. Based on the analyses of transition matrixes, diversity and fragmentation indexes, and spatial distribution alternation of the wetlands, we found the landscape diversity and fragmentation indices increased while wetland dominance index decreased dramatically. Among the wetland types, the areas of the river-channel, reservoir and pond wetlands increased while the areas of the lake and marsh wetlands decreased continuously. |
