Abstract

Analysis of information from about 287 sample plots on Northeast China Transect (NECT) indicated that between 1986 and 1994 at latitude 43.48° N to 43.55° N and longitude 124.93° E to 131.28° E, the relative abundance of different tree species changed differently. The change of relative abundance for the moisture-sensitive tree species, such as Quercus mongolica and Larix olgensis, was helpful to detect climate change. Use of GIS software and the α and βw indices of tree diversity on NECT showed that the areas of high and medium tree diversity decreased, respectively, while the area of low tree diversity increased. The heterogeneity of habitats along the NECT increased with climate change and local human activities.
