The Three Gorges;ecology
SUMMARY About 250 trees, representing 10 species, were collected from the Chi- nese Three Gorges Reservoir region as part of a study to use tree rings as indicators of environmental change in this area. Five species do not show distinct ring boundaries or cannot be cross-dated with each other. The dendrochronological potential of the remaining fve species, two conifers and three hardwoods, are assessed in this paper. These fve species, Cathaya argyrophylla, Cinnamomum camphora, Gordonia acu- minata, Pinus massoniana, and Scheffera delavayi, have distinct an- nual growth rings and little occurrence of double or missing rings. Tree- ring width and maximum latewood density chronologies from the fve species range in length from 38 to 138 years. These relatively short chronologies are just long enough to conduct a preliminary dendro- climatic evaluation. Preliminary climate modeling demonstrates some signifcant relationships between tree-ring data and temperature, pre- cipitation, and river fow. Key words: Tree-ring width, maximum latewood density, dendro- chronological evaluation, Chinese Three Gorges Reservoir, Cathya argyrophylla, Cinnamomum camphora, Gordonia acuminata, Pinus massoniana, Scheffera delavayi.
