A Study of Landscape Pattern of Land Consolidation Based on GIS and Landscape Ecology
摘要
Abstract
Using GIS technology as well as theory and methods of landscape ecology,the authors studied landscape pattern of land consolidation. Exemplified by the land consolidation key project for Huainan city, the authors selected three targets and probed into the land use situation and landscape pattern before and after land consolidation. The changes of land use structure and landscape patterns based on land consolidation were analyzed using Geographical Information System combined with the method of landscape ecology, and some results were obtained. First, paddy fields are predominant in the landscape pattern, and the patch fractal dimension and the shape parameters tend to decrease gradually, indicating that the pattern of patches has become regular and simple.Second, the number of landscape patches and patch densities are relatively low, the average patch area and the maximum patch area increase, and the maximum patch index rises steadily. All this shows that landscape diversity has been reduced simultaneously with the increase of the landscape distribution uniformity.关键词
