Microclimate Characteristics of Different Microhabitats of a Rare and Endangered Bamboo of Drepanostachyum luodianense Communities

The microclimate characteristics in different microhabitats of different D.luodianense communities were studied by field investigation.The results showed that stone surface light intensity was the highest of all,its high air temperature lasted for a long time,its relative air humidity was low,and there was little soil on it,so that D.luodianense didn't distribute in stone surface;the air temperature and soil temperature of stone cavern were lower than others,light intensity was largly different among different slope position,D.luodianense was sparse in stone cavern and growing weakest;the light intensity,air temperature,relative air humidity and soil temperature of soil surface were most suitable and stable,it was the best for D.luodianense.
