天全县香果树种群资源调查报告
|
摘要
香果树为国家Ⅱ级重点保护植物,种群数量极小。为了科学合理制定香果树保护对策,根据芦山地震灾后重建总体部署和《芦山地震灾后恢复重建生态环境修复专项规划》安排,对天全县香果树资源状况进行了全面调查。本文采用咨询、访问、样线、样方调查相结合的方法对天全县的香果树种群资源及其生境进行了调查分析。结果表明:天全县现有香果树62株,种群数量少,开花结实偶见,天然更新能力差,幼苗幼树缺乏,成年植株长势较差,病虫害较为严重,种群呈衰退趋势。现有香果树资源集中分布于紫石、仁义、小河等乡镇,径级集中在8 cm~22cm之间。香果树生境群落植被丰富,乔木、灌木、草本、蕨类植物分别有19种、15种、30种、11种,其种间竞争处于劣势。天全县香果树分布集中于海拔1 000 m~1 400 m的山坡下部、山谷和沟底,空气湿度大,土壤相对瘠薄。
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.
