LARIX PRINCIPIS-RUPPRECHTII 'S RADIAL GROWTH-CLIMATE RELATIONSHIP AT DIFFERENT ELEVATIONS IN LUYA MOUNTAINS
摘要
Abstract
Tree cores of Larix principis-rupprechtii were taken from 3 sites at different elevations to stand for the trees' growth in Luya mountains, correlation analysis, single year analysis and multiple regression method were carried on to correlate growth-climate relationship. Data showed that temperature and precipitation factors combined impact radial growth at each elevation; influence of precipitation factors on growth was found to be stronger than temperature factors. In growing season, tree radial growth was limited by soil drought at low elevation, but by low temperature at high elevation. In growing season, the positive correlationship was reversed to negative between tree radial growth and precipitation factors with increasing elevation. With elevation climbing from 1 972 to 2 237 m, precipitation in growing season increased sharply, eventually surpassing limitation precipitation threshold.关键词
