查询词典 wetland

In the study, research aims at setting up a suitable framework to assess the farmland wetland by introducing proper wetland evaluation technology. Here, a two-stage qualitative 'multiple value evaluation matrix' is proposed and practiced for the 'Eco-park' planning at Fubao wetland in Changhua. Those functions such as sustenance, socio-education and production are approaching to the positive evaluation. On the contrary, the impacts induced by improper restoration planning on normal function of wetland are considered as negative evaluation. There are 70 indicial elements altogether, including some critical-value elements with importance meaning to the sustainable development in wetland. They are enhanced their weigh to strengthen the unique characteristic of wetland.

Planted wetland had a removal rate of organic matter 2.2% lower than unplanted wetland in winter with plant harvested. In other seasons, the removal rate of CODCr in planted wetland was 3.2%～4.2% higher than that in unplanted wetland, while BOD\-5 was 1.8%～4.8% lower than that in unplanted wetland.

结果表明，在植物收割后的冬季，有植物湿地对有机物的去除率低于无植物湿地2.2%；在其他季节，芦苇湿地对污水CODCr的去除率比无植物的高出3.2%～4.2%，但对BOD5的去除率却比无植物的低了1.8%～3.4%。

Planted wetland had a removal rate of organic matter 2.2% lower than unplanted wetland in winter with plant harvested. In other seasons, the removal rate of COD, in planted wetland was 3.2%~4.2% higher than that in unplanted wetland, while BOD5 was 1.8%~4.8% lower than that in unplanted wetland.

The wetland has significant function for mankind of storing floodwater,fight drought, complement groundwater ,adjust climate, prevent soil corrade ,reduce environmental pollution .because it has abundant natural resources,special ecological environmental and structure.The countries all over the world strength on protecting wetland,taking on any masures to prevent the wetland degeneration and disappearance. Studies on the restoration and reconstruction of disturbed wetland become the hotspot of world environmental study.

湿地由于其独特的生态功能和结构，具有蓄洪抗旱、补充地下水、调节气候、防止土壤侵蚀、保护生物多样性、降解环境污染、促淤造陆等对人类具有重要意义的功能，所以世界各国都在加强湿地的保护，采取各种措施防止湿地的退化和消失，湿地的生态恢复和重建已经成为世界环境科学研究的热点。
