摘要
用四种不同生态类型的水生维管束植物分别研究其对水中有机物的吸收、有机氯农药的积累、亲巯元素(铜、铅、镉)的富集。试验结果表明水生维管束植物有较强的净化水体能力。特别是飘浮性植物凤眼莲、芜萍对以上几种污染物的吸收率高、耐污性强,且该植物生存的适应性广,并容易从水体中分离,是理想的净化品种。把这些植物应用到生态系统工程中,是一项投资少、设备要求简单,见效快的处理污水措施。
This experiment conducted in the four different ecosystems was to study theabsorption of organic matters in the water, accumulation of chlorine pesticidesby various aquatic vascular plants. Experimental tesults have shown that thefloating plants including water hyacinth and water lettuce have the highestabsorption rate of those wasted substances, moreover, such plants have thestrongest adaptability and easily available. Therefore, they are taken as thesuitable species used for water purification in the ecosystem engineering, whichneeds less investment facilities, but with quicker and better effects.
