چکیده انگلیسی
This study investigated changes in the population distribution pattern of Spartina spp. along China's coast over a period of more than 30Â years. Remote sensing, in conjunction with geographical information systems (GIS), global positioning systems (GPS), and on-site investigations were used to map salt marsh vegetation along the entire coast. Species recognitions were checked subsequently using in situ field surveys of selected areas. Results showed that the distribution of Spartina anglica has been greatly degraded from 33,333Â ha in 1981 to only 16Â ha in 2007. By contrast, Spartina alterniflora had spread widely from being absent in 1981 to an area of 34,451Â ha by 2007 from Liaoning Province to Guangxi Province. Nearly 94% area of the area covered by S. alterniflora is distributed in Jiangsu, Shanghai, Zhejiang, and Fujian Provinces, representing the most highly concentrated areas in China. Knowing the current expanse of this species, including its quantity and spatial patterns, is useful for predicting the future proliferation of S. alterniflora. Coastal ecosystem health of the China coast can thus be better assessed.
