Abstract

Emmenopterys henryi is one of the second-class protection plants of China,whose population amount is very scanty. In order to draw up a scientific and rational protection measures of Emmenopterys henryi,according to Lushan post-earthquake overall deployment and 《Lushan post-earthquake ecological environment recovery and rehabitation professional plan》,investigations were made on the Emmenopterys henryi resource in Tianquan County. The methed was to combine a resources survey with counseling,visiting,and quadrat investigation,and analysis was made of the ecological environment. The result showed that there were 62 Emmenopterys henryi trees in Tianquan County. The population was less and exhibited a declining trend,and diseases and insect pests were serious,lacking of seedlings and saplings and natural regeneration. Emmenopterys henryi trees were distributed in Zishi,Renyi and Xiaohe township,while their diameter was mainly concentrated between 8 cm and 22 cm. The vegetation of Emmenopterys henryi habitat was rich,and trees,shrubs,herbs,ferns respectively were 19 species,15 species,30 species and 11 species,and their inter specific competition was at a disadvantage. Their geographical distribution was concentrated at lower slopes,valleys and ditches between the altitude of 1 000 m and 1 400 m, where ambient air humidity was big and soil was relatively infertile.
