摘要: |
于1989~1990年、1992年、1995年、1997~2000年以及2004年1月,分别按季节先后考察南流江河口湿地的鸟类种类和数量。结果在南流江河口湿地共记录到158种鸟类,分别属于15目47科,其中水鸟有75种,陆生鸟类有83种。该地区的鸟类以冬候鸟为主,共80种,占种数的50.6%;留鸟、旅鸟、夏候鸟分别为32种、31种、15种,属于国家重点保护及国际协定保护的鸟类有123种,各占该地区鸟类种数的20.3%、19.7%、9.5%和77.9%。 |

Abstract: |
To study the correlationship between DIP and chlorophyll-a(chl-a) in different model's water of shrimp culture,we tested the pH value and COD in 8 industrialized culture ponds and 4 normal ponds during 15th~19th,Oct.,2001,and drawed the water samples for DIP and chl-a analyse in laboratory.The industrialized shrimp culture model with high density,high forage-fed and the normal model with low density,low forage-fed, were undertaken at the culture base of Guangxi Institute of Oceanography.The DIP and chlorophyll-a contents of industrialized model were 0.82~1.59mg/L and 1.71μg/dm3 respectively,showing high DIP and low plant biomass in the environment of water.But in the normal model, the environment of water was characterized as low DIP and high plant biomass,while they presented as 0.041mg/L of DIP and 3.94~6.86μg/dm3 of chlorophyll-a.The results of correlation analysis showed that,in the two model's water,DIP and chl-a had a strong negative correlation(r=|-0.791|~|-0.927|> r0.01=0.708),at the same time,DIP and COD,had a strong positive correlation(r=0.818~0.904> r0.01=0.708),DIP and pH value,had 3d negative correlation(r=|-0.685|~|0.750|> r0.05=0.576).The important effective factors to DIP and chl-a are the illumination and the nutrient salt. |
