大面积水草草害的综合防治研究

介绍了大面积水草草害综合防治的研究背景,并对水葫芦为主体的大面积水草泛滥成灾的原因作了分析,认为主要是由于不恰当生产、生活活动,导致水体污染加剧和转化、产出链的裂断所致.同时认为,只有运用循环经济和生态经济学原理,采取行政和科技“双管齐下”,才能切断内外源营养物质对水葫芦的有效供给;同时也要充分发挥其原有净化水质的独特功能,强化转化、产出链,即通过加工饲料、肥料和食用转化等,就能“变害为利”,并使江南平原水网的生态系统得以在新的层次上进行重组和整合,以达到逐步恢复平原河网原有水质和良性循环的目的.

Research on comprehensive prevention and harnessing of extensive aquatic plants harm

The cause of extensive aquatic plants,which is mainly water hyacinth,is introduced in the paper.It shows that water pollution and links rupture are the key causes owing to irrrelevancy life and works.The principle of cycle economy and ecological economics is only exerted to cut off alimentation supply.The administration and technolongy means are also used to control the total aquatic plants.At the same time,it is needed to clarify the water quality and to proccess them into feedstuff and fertilizer.With these measures,a new conformity will come into being in ecological system on a new level,achieving the purpose of better water quality.
