The paper presents the results of investigations on the macrophytes of Lake Tung-Hu,Wuchang,carried out in the year 1962—1964.83 species,which constituted theaquatic vegetation,are listed.Data on biomass,based on sampling along 21 transects(involving 3 zones,17 plant-associations,and 224 sampling positions),are presented,and a comparison is made for the macrophytic biomass of 6 shallow lakes of theMiddle and the Lower Yangtze Basin.The monthly changes in biomass of 2 tran-sects (Ⅻ & ⅫⅠ) have been followed up through the year.The biomass conditionsfor zones of different depth-ranges are analyzed.Lake Tung-Hu,28.5 km~2 in area,had a peak average biomass of 1068.1 g (wetweight) or 94.8 g (air-day weight) or 82 g (oven-dry weight) or 322 kcal per squaremeter in August.Annual production of aquatic vegetation in the whole lake amo-unted to 30,440 metric tons in wet weight,or 2,337 t in oven-dry weight,or 9×10~9kcal in terms of calorific value.Potamogeton maáckianus ranked first in the pro-duction,being 38.2% of the total wet weight or 52.5% of the total air-dry weight,andit was followed by Najas major,Myriophyllum spicatum,Hydrilla verticillata andCeratophyllum demersum in turn.In the lake,the annual primary production from aquatic macrophytes and phy-toplankton put together amounted to 25×10~9 kcal,of which the aquatic macrophytescontributed 36%.In passing,the authors discuss the problem of the rational utilization of this re-source in special regard to pisciculture,and a formula is proposed for calculating thestocking density of the phytophagous fish,for instance,Ctenopharyngodon:X=(B·P/K·W·S),in whichX——the number of fingerlings of the phytophagous fish to be stocked per mou (1mou=1/15 hectare)B——maximum average biomass (attained during August—October) of the macro-phytes suitable for fish consumption (in catties per mou) (1 catty=500 g)P——percentage of the macrophytic biomass intended to be consumed by the fishK——gross feed-coefficient of the phytophagous fish during the entire growing sea-son (in catties)W——expected average increase in weight per fish (in catties)S——percentage of the number of survivors (to the end of the growing season) tothe number of fingerlings stocked

本文是根据1962—1964年部分调查研究资料整理而成的。文中列出了83种水生维管束植物(以下简称水生植物)的名录,比较了全湖21个采集断面、3个植物带和17个植物群丛以及长江中下游6个浅水湖泊水生植物的生物量,分析了东湖两个断面(Ⅻ和ⅪⅡ)的生物量的周年变化和湖中不同水深区的生物量变化情况。全湖面积为28.5平方公里。8月是生物量的高峰期,平均每平方米的生物量为1,068.1克(湿重)或94.8克(风干重)或82克(烘干重)或322千卡(能量)。其中,以黄丝草所占的比例为最大,其次为大茨藻、聚草、黑藻和金鱼藻。全湖水生植物的年生产量为30,440吨(湿重)或2,337吨(烘干重)或9×10~9千卡(能量),连同浮游植物(16×10~9千卡)一起,则东湖全年的原初生产量为25×10~9千卡,其中水生植物约占总原初生产量的36%。本文最后讨论了水生植物在湖泊渔业上的合理利用问题,提出了草食性鱼种放养量的计算公式和合理利用水生植物资源的建议。

In this paper, after giving a general diseussion of the development of railway motive power in China and an analysis of the rational utilization of power resources, it is pointed out that electrification is the natural tendency of development in various countries of the world. Practical railway operation in China has also proved that electrification is superior to other means of motive power and should also be the direction of her development.

本文概述了我国牵引动力的发展,并从能源合理使用角度,指出铁路电气化是世界各国发展的必然趋势。我国铁路运输的实践证明,电力牵引比其他牵引方式优越,铁路电气化应是我国铁路发展的方向。本文还从理论计算表明:电力牵引比蒸汽牵引、內燃牵引有较好的技术经济效果、较大的线路区间通过能力和货物输送能力。作者还进一步研究了各种牵引动力在不同线路及不同运量条件下的适应范围,并指出我国铁路牵引动力现代化,应贯彻电、內并举,以电力为主的方针,首先应在运输繁忙的干线上采用电力牵引,以加速我国铁路牵引动力改造,适应国民经济高速发展对铁路运输的需要。
