摘　　要：以沅江市为研究对象,利用GIS技术对沅江市景观格局进行动态研究,结果表明:1)1996―2014年沅江市在景观水平上,优势度减小,受人为干扰程度增大,趋于分离化发展,斑块类型均匀度增大,生物多样性增加;2)1996―2014年沅江市耕地、林地景观优势度减小,林地、库塘受人为干扰程度增大,建设用地、水域景观优势度增大,水域、库塘景观趋于聚集化发展,泥滩地、耕地景观趋于分离化发展。This paper took the Yuanjiang city as a study subject. Using GIS technology to carry on the dynamic research, and in order to provide the reference for the ecological environment protection and construction of Yuanjiang city in the future.

The results showed that： 1） In terms of landscape level of Yuanjiang city in 1996--2014, the degree of disturbance of the landscape was reduced and the degree of disturbance was increased, and the uniformity of the patch type was increased and the biodiversity was increased. 2） In 1996--2014, the landscape of Yuanjiang city dominance of cultivated land and forest decreased, forest and ponds were easily interfered by human activi- ty, the landscape dominance of construction and waters increased ; waters and ponds landscape tended to gather development, muddy land and cultivated land landscape tended to separate development.
