[Landscape pattern in Northeast China based on moving window method].
Based on GIS technology and by using moving window method, the characteristics of landscape pattern in Northeast China in 2006 and the relationships between these characteristics and environmental factors such as precipitation, air temperature, altitude and human activities were studied. In the study area in 2006, forest land had the largest proportion, followed by the cultivated land, occupying 61.69% and 25.11% of the total respectively, and the landscape diversity had the characteristics of circle-zoning structure, which provided a buffer region for fragmented and sensitive regions, making the adverse ecological consequences be reduced to or restricted in a definite scale. The correlation coefficients of landscape indices with precipitation and air temperature were less than 0.4, and those with altitude were less than 0.07, illustrating that the heterogeneity of landscape pattern in study area was not dependent on single natural factors.
