摘要
南四湖菹草爆发对水质安全和生物多样性保护造成了较大压力。通过分析南四湖菹草分布现状和爆发成因,研究总结了菹草治理的模式和方法。提出从外源治理、内源治理两方面综合施策,科学治理南四湖菹草爆发式增长。外源治理应以治污为主,严格控制外源输入污染。内源治理采用“养、割、清、种”四字方针,合理控制菹草发生规模。同时,多方面加大菹草资源化利用研究,达到“以用代治”的效果。
The outbreak of Potamogeton crispus in Nansi Lake has caused a great pressure on water quality safety and biodiversity protection.Based on the analysis of the distribution status and causes for outbreak of P.crispus in Nansi Lake,the control model and method of P.crispus were summarized.It is suggested that the explosive growth of P.crispus in Nansi Lake should be controlled scientifically by comprehensive measures from both external and internal sources.External source control should focus on pollution control and limit external source input pollution strictly.Internal sources control should adopt the four character policy of "breeding,cutting,clearing and planting" to control the occurrence scale of P.crispus appropriately.At the same time,the studies on resource utilization of P.crispus should be strengthened in many aspects to achieve the effect of "utilization instead of control".
