蒲石河蓄能电站河岸带近岸砂积地形草本植被分布特征

用样方器采集植物样品的方式在蒲石河蓄能电站河岸带覆砂地带进行植被调查。河岸带植物密度和高度优势种株树与高程相关,相关系数分别为0.687和0.701。蒲石河抽水蓄能电站河岸带按照高程、植被分布规律和距水距离,可以划分为喜水植物茂盛带(距水距离为0~4 m)、混生低草带(距水距离为5~15 m)和非喜水植物茂盛带(距水距离大于15 m)。样方植物株数、植株平均高度、数量优势种株数、单位面积生物量(鲜重)等指标规律分布,是蒲石河蓄能电站植被研究特征指标。土壤覆砂状况对植株高度与种类数量等有影响。

Herbal Vegetation Distribution Characteristics in Riparian Sand Deposition Zone of Pushi River Pumped -storage Power Station

Plant samples of riparian vegetation at Pushi River Pumped - storage Power Station were collected with quadrat device. It was found that the stock numbers of plant density and height - dominant species along the riparian zone are correlated with elevation, of whose correlated coefficients were 0.687 and 0.701, respectively. According to the surface height, the regularity of vegetation distri- bution and distance from water, the riparian zones of Pushi River Pumped - storage Power Station can be divided into flourishing zone of hydrophilous plants （0 -4 m from water）, low grass zone of mixed floras （5 -15 m from water） and flourishing zone of nonhydrophi- Ious plants （greater than 15 m from water）. Stock numbers of plants of the quadrats, average height of plants, stock numbers of quan- tity- dominant species and biomass per unit area （fresh weight） are characteristic indexes of vegetation research of Pushi River Pumped -Storage Power Station which are regularly distributed. Sand on soil surface has influence on the variety, quantity of species and the height of plants.
