[Effect of landscape pattern on mouse pest in Dongting Lake area]

The relationship between landscape pattern and ecological process is one of the key issues in landscape ecology. Both the species protection and the bio-disaster prevention are closed linked with the landscape pattern of organism's habitat. Taking Dongting Lake area as a case, this paper studied the characteristics of landscape pattern in typical sampling plots, and analyzed the correlation of mouse capture rate in farmland and in house with the indices reflecting the characteristics of landscape pattern. The results showed that the mouse capture rate in farmland correlated significantly with the landscape aggregation, connection, and mosaic shape, while that in house had a significant correlation with the mosaic shape of construction land. Some suggestions on reducing mouse pest were put forward from the viewpoint of landscape pattern.
