摘要：Wetlands are resources of paramount importance with many values and functions. However, with the economy development and the population growth, wetlands have undergone great changes. This study investigated the land-cover and landscape pattern dynamics of Guide wetlands in the periods 1977-2006. Four Landsat images were used to locate and quantify the changes. The study revealed the area of wetlands previewed a downward trend during the past 30 years, whereas the area of cultivated land increased all the time. From 1997 to 2000, the wetland landscape pattern became more fragile and less connective. The landscape types converted to each other dramatically. During 2000 to 2006, both dominant and contagion indices on the whole area were enhanced. Its driving forces were analyzed according to socioeconomic development and climatic information. Remote sensing (RS) and Geographic information system (GIS) technologies have proved to be useful tools for assisting decision-makers to locate and quantify changes in land resources, and hence to identify appropriate solutions for sustainable management of wetlands
