Abstract

Abstract:

So far as we know, global warming has notably changed the patterns of the biomes on earth. As the increasing activity of plant growth in high latitudes has been confirmed, the plant growth trend in tropics is still a controversial question concerned. Xishuangbanna Tropical Botanical Garden is located in southwestern China, and the climate here has changed significantly during the past a few decades. As the temperature rose averagely 018℃ per ten years since 1970s, how would the plants here respond? Here we used the longterm height plant growth data (1974-2003) of 48 tropical conserved species from 28 families in the botanical garden to present their interannual variation of growth responding to the regional climate change. Correlation analysis between the interannual climatic factors and the plant heights were performed to reveal the key climatic factors. Result shows as followed. For the conserved species in Xishuangbanna, interannual mean plant height varies strongly along years since 1974; however, no significant trend is shown. Height growth of the introduced species is mainly impacted by the sunshine duration (negative) and mean minimum temperature (positive) in dryhot season (March and April), which is the period when these plants begin to flush leaves. Yet, rainfall is not included in these key factors. In the perspective of the trends of the 2 key factors, growth of the plants in the botanical garden is expected to be benefited. And this will also benefit the conservation work for tropical plants in the botanical garden.

Key words: Climatic factors, Inter-annual variation trend, Plant height deviation, Xishuangbanna
