| 摘 要： | 在我国典型的草型湖泊——内蒙古乌梁素海设立试验示范基地,进行较大规模沉水植物收割工程试验,探索以机械化方式收割沉水植物转移氮、磷营养盐对草型湖泊进行生态治理的实用技术。试验表明:有计划、合理地收割沉水植物不仅能够有效地削减草型湖泊内源性营养物负荷的积累与释放,使输入与输出的营养盐趋于平衡,使湖泊生态系统逐渐进入良性循环状态;而且不影响沉水植物的繁殖与再生,不会造成藻类蔓延。从而解决了草型湖泊富营养化适度控制的生物治理技术可以长期正常运行的一个关键问题,提供了在湖泊生态治理的同时可以持续开发利用沉水植物资源的可能性。

| Abstract: | The experiment demonstration base was established in Wuliangsuhai Lake that is a typical
macrophyte--dominated lake in China. In this base, the harvesting project experiments of sub-
merged plant have been carrying out on a large--scale. The aim of those experiments is to search for
a utility technology that can improve the environment of plant type eutrophic lake by harvesting
submerged plant to transfer nitrogen and phosphor nutrients. The result of those experiments in-
dicated that the planned and reasonable harvesting submerged plant can effectively cut back the
accumulation and release of inner nutritious loads. At the same time, it also can make the lake
environment achieve the balance between input and output nutrients and make the lake enter into
good circulation gradually. Except of the above, it can' t affect the reproduce of submerged plant
and result in the blooming of algae. Therefore, the key problem that the ecological management
technology may chronically and normally work can be resolved. The technology can be used to
moderately control macrophyte--dominated eutrophic lake. Applying the technology make it possible
to manage lake environment and continually utilize submerged plant resource simultaneously. |
