生物多样性

Poyang lake, 4600 square kilometers in the normal flooding level, is the biggest freshwater wetland in china, and famous with its extremely abundant biological variety, especially with a large number of the rare and endangerous species,such as Grits lemcogeranus, G. monacha and Ciconia byciana .

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。

Culturable heavy metal-tolerant bacteria in 5～10 cm and 25～30 cm layers of three lead-zinc tailings,deposited for about 10,20 and 80 years respectively,were investigated.

重金属毒性往往对土壤微生物的生物量、代谢活力产生不利影响[1] ，导致微生物区系组成的改变和生物多样性的减少[2 ] 。

However, as a result of human activity especially moorland is reclaimed, the aggravate that uses favourable geographical position waiting for earth of chemical fertilizer to use an activity in great quantities, and large-scale disafforest and habitat are broken the change that spends favourable geographical position waiting for earth to use structure, played havoc with natural landscape, the change moves floral to live environment, make ecosystem function degrades, brought about the forfeiture of biology diversity finally.

然而，由于人类活动尤其是荒地开垦、化肥的大量使用等土地利用活动的加剧，以及大规模砍伐森林和栖息地破碎化等土地利用格局的改变，严重破坏了自然景观，改变动植物的生存环境，使生态系统功能退化，并最终导致了生物多样性的丧失。
