| 英文摘要 | Landscape connectivity is an efficient index measuring the continuity of the spatial landscape units, and reflects the functional characteristics of the landscape. The coastal wetland ecosystem in the Yellow River Delta which have high ecosystem service functions have changed greatly due to local development. Therefore, it is necessary to analyze the dynamic changes of the natural wetland landscape in the Yellow River Delta and to explore the causes. In this study, Landsat TM images from 1991 to 2013 were used to evaluate the changes of landscape connectivity using connectivity index based on the graph theory. The dynamic characteristics of wetland landscape connectivity were analyzed at both regional and local scales and the driving factors of natural wetland landscape connectivity in the Yellow River Delta were also discussed. The results showed that the landscape connectivity of natural wetlands in the whole delta from1991 to 2013 was generally low and declining gradually, with the maximum possible connectivity index of less than 0.1, and the area of natural wetlands decreased by 548.75 km~2. The area of natural wetlands in the Kenli agro-ecological zone, Estuary agro-ecological zone and Shengli oilfield zone severely decreased, and the degree of landscape connectivity dropped significantly. By 2013, the landscape connectivity index in these zones dropped below 0.01. However, the landscape connectivity and wetland area of Yiqianer management station and the Yellow River mouth management station had increased. In the meantime, the connectivity indices of both stations were all above 0.5, and the possible connectivity of the Yellow River mouth management station increased from 0.203 to 0.360. It indicated lower landscape connective patterns in inland wetland than those in the Yellow River delta nature reserve. Farm land, artificial wetlands and construction land werethe main driving factors that affected the changes of wetland landscape connectivity. Therefore, we strongly recommended to expand the area of nature reserves in the future, and increase the number of footsteps to increase habitat connection to improve landscape connectivity in the Yellow River Delta. |
