The contents of organic matters, tn and tp in sediment layer from 0 - 20cm also decreased after 2 months of harvested, but nh / - n and no3 - - n increased due to the amelioration of transperancy and aeration, which accelerated ammonification and nitrification
2個月以後,收割區底泥0 - 20cm深度范圍內有摘要機質、 tn 、 tp含量明顯下降,收割改善了
濕地的通風、透氣條件,促進了氨化和硝化作用的發生,使底泥中nh擴一n和n島一n含量上升。

Wetlands have unique biogeochemical cycles with many chemical transformations and chemical transport processes that are not shared by many other ecosystems
摘要
濕地有其獨特的生物
地球化學循環,其間許多化學遷移和轉化過程不為其它生態系統所共享。
In order to understand the effects of drainage ditches on the biogeochemical cycling in wetland, this paper takes the sanjiang plain as an example, and makes a detail introduction to the impacts of drainage ditches on the characteristics of movement, transformation, inputs and outputs of chemical elements and on the chemical mass balance

The number of black - faced spoonbills found in minjiang estuary wetland, changle city has been increased to 12. after finding 2 endangered black - faced spoonbills on 1 march 2003 in tantou town, changle city, 10 more were found at the same place on 17 april, and 3 of them already had breeding plumage. it is estimated that the additional flock of black - faced spoonbills arrived here during migration and stopped by here to rest and feed

For some wetland plants such as reed and cattail, a small quantity of petroleum pollutants did not form deadly menace, their growing tallness was positive correlated with water deepness. therefore, wetland buffer can be constructed to reduce the impact of petroleum pollution and plant adaptive wetland vegetation so as to improve the environment of oil field
結果顯示:
濕地環境對土壤中的石油污染有明顯的降解作用,蘆葦等挺水植物的生長量與積水深度呈正相關,土壤中少量含油並不構成對
