江西水生维管束植物和群落的生态地理分布及其保护

ECOLOGICAL GEOGRAPHICAL DISTRIBUTION AND PROTECTION OF AQUATIC VASCULAR PLANTS AND AQUIHERBOSA IN JIANGXI

笔者调查了６８个水域的水生草本植物群落。记载了各植物群落的组成成分；测定了水环境的理、化状况。发现纬度地带性因素，垂直地带性因素，水化学性质，水体底质状况，水的流速及水体透明度等，对植物群落的分布及其种类成分具有综合的影响；

The Writers have investigated phytocoenosiums of aquatic vascular plants of 68 waters.The article has recorded every aquiherbosa constitutive composition,conditions of physics and chemistry of the aquatic environment have analysed.We have discovered the iatitudinal zonal factor,the vertical zonal factor,the quality of aquatic chemistry,the conditions of waters benthic matter,the aquatic velocity of flow and the waters transparency,etc.,of these,be possessed of comprehensive effect on phytocoenosium's distribution and species composition.This article also details with the relevant questions on protection.
