- Abstract:
- In the support of the software of ArcGIS 9.2 and Fragstats 3.3, based on the GIS technology, the method of overlay analysis and landscape indices analysis was used to research into the dynamic change of landscape pattern and discuss the relationship between the change of landscape pattern and ecological processes in upstream mountain area of Huaihe basin among the year of 1990,1995 and 2000.The main results reveal that: (1)The landscape structure of the study area has almost no change from the year of 1990 to 2000. (2)The trend that campagna paddy field become into campagna dry land, woodland and country residential area was remarkable in study area among 10 years. (3)In study area, the heterogeneity of landscape were increased while the spatial aggregation and connectedness of the study area was worsen among the 10 years. (4)Compared to the foregoing 5 years, several landscape components’ fractal dimension was decreased and the spatial aggregation and connectedness was improved in the after 5 years. (5)The structure and function of ecosystem are in the state of getting worse and worse with the exception of some small areas being improved in study area.
