Analysis of Ecological Landscape Pattern Change in the Poyang Lake Eco-Economic Zone of China

Abstract:

In this paper, based on RS and GIS technology and landscape pattern analysis, the changes of ecological landscape in the Poyang Lake Eco-economic Zone were analyzed from 1990 to 2005. Main results are as follows. There was a decreasing trend of wetland and forest from 1990 to 2005. The result of landscape pattern analysis showed that there was an increase in the degree of fragmentation of ecological landscape in the study area. The increased Perimeter-area fractal dimension indicated the shape of ecological landscape became more and more rules. Aggregation Index (AI) of lake increased from 86.0066 in 1990 to 86.123 in 2005, which showed that the overall aggregation degree of ecological landscape in the Poyang Lake Eco-economic Zone is in rise.
