| [population expansion of spartina alterniflora and phragmites australis at jiuduansha, shanghai based on cellular automata model]. | based on the field survey and the interpretation and analysis of satellite images about the population expansion patterns of spartina alterniflora and phragmites australis at jiuduansha shoals in 1997-2004, and combined with 3s techniques, a cellular automata (ca) model was built to simulate the population dynamics of plants adaptable to salt marsh. the results showed that the model could well simulate the population expansion pattern and trend of s. alterniflora and p. australis at jiuduansha, ... | 2007 | 18333459 |
| [difference and its formation cause in soil organic carbon accumulation capability of two typical tidal wetlands at dongtan of chongming island in shanghai]. | through the analyses of soil organic carbon content and vegetation input, this paper studied the difference in soil organic carbon accumulation capability of two typical tidal wetlands, one (a) was on the erosion bank with phragmites communis and sandy loam soil at southeast dongtan in shanghai, and the other (b) was on the alluvial bank with p. communis, spartina alterniflora, and clay soil at northeast dongtan of chongming island. the main formation causes of the difference were analyzed based ... | 2009 | 19795638 |
