The extreme weather of high temperature and drought occurred in 2013 from June to August in south of Yangtze River area. The damage of high temperature and drought ought stress on Moso bamboo(Phyllostachys edulis) stands in Fuyang of Zhejiang Province was investigated. The relationship between environmental factors and damage degree of bamboo stands was analyzed. The result showed that the bamboo leaf was hurt severely with burning appearance and in color of withered and yellow, even lost all leaf. The damage on stems depended on bamboo age. One-year-old bamboo appeared stem dehydration, and black spot occurred in the base part of stem, four-year-old bamboo showed slight black spot but no stem dehydration, six-year-old ones appeared no black spot. The death ratio of two-year-old bamboo was higher than that of the older bamboo under the stress of high temperature and drought. The CCA analysis suggested that the damage ratio of bamboo stands significantly depended on the soil depth, slope direction and slope po
