The objects of this projects are to know the water purification capacity, to get a design guidelines for water pufification using a macrophyto, water Hyacinth (Eichhornia crasipes (Mart) Solms) and to investigate the utilization of water hyacinth to animal foods. In order to achive the objects mentioned above, the following subjects are included:(1) Effects of nutrients concentration in water on the growth of water hyacinth(2) Cralification of the relationship between the growth rate and the cultivation dencity of water hyacinth(3) Effects of harvesting management of water hyacinth on water purification capacity(4) The relationahip between the accumulation of heavy metals to water hyacinth and the inhibition of the growthWater hyacinths were cultivated using the natural water-way for irrigation water and the artificial channel setted in a green house for conducting the above subjects.(5) Utilization of water hyacinth to animal foodswater hyacinth cultivated in the natural water-way were used for this study.

本研究的目的是了解水的净化能力，获得利用水生植物水葫芦（Eichhornia crasipes（Mart）索尔姆斯）净化水的设计准则，并研究水葫芦作为动物饲料的利用。为了达到上述目的，本研究主要包括以下几个方面的内容：（1）水体营养盐浓度对水葫芦生长的影响;（2）水葫芦生长速率与栽培密度关系的阐明;（3）水葫芦收获管理对水体净化能力的影响;（4）重金属对水葫芦的富集与水葫芦生长抑制的关系。(5)水葫芦在动物饲料中的应用本研究以自然水体中栽培的水葫芦为试验材料。
