The effects of <i>Bellamya sp.</i> on the growth of two submerged macrophytes in Lake Taihu

Journal of Lake Sciences (2007)

Xiuling Bai Xiaohong Gu Yu Zhang

环棱螺(Bellamya sp.)是太湖常见的一类软体动物.本研究通过室内实验.探讨环棱螺对轮叶黑藻(Hydrilla verticillata Royle)和伊乐藻(Elodea nuttalli ST John)生长的影响及水体营养盐含量的变化.结果表明, 三种处理情况下, 单位质量伊乐藻增加的数量分别为:H组0.475 g, L组0.106 g, C组0.021 g, 单位质量轮叶黑藻增加的数量分别为:H组0.704g, L组0.663 g, C组0.478 g.从实验前后两种沉水植物的长度和分蘖数变化来看, H组最高, L组与C组分别次之, 所以不论生物量、长度还是分蘖数的变化量, 与环棱螺共存的伊乐藻和轮叶黑藻的变化都高于对照组中两种沉水植物的变化.环棱螺新陈代谢促进水体中溶解态氮磷含量增加, 三种情况下水生植物的初级生产力都相当, 由此可推测环棱螺通过新陈代谢, 一定程度上促进了两种沉水植物的生长.;Bellamya sp.snails are very common in Lake Taihu.The effects of snail(Bellamya sp.) on the growth of Hydrila verticillata Royle and Elodea nuttalli ST John and dissolved nutrition elements were examined in a laboratory.After a week of exposure of snail and aquatic plant in a experiment, increments of the per unit of Hydrilla verticillata Royle in three groups were :H :0.475 g, L :0.106 g, C :0.021 g and increments of the per unit of Elodea nuttalli ST John were H :0.704 g, L:0.663 g, C :0.478 g respectively.In addition, the change of length and node of Hydrilla verticillata Royle and Elodea nuttalli ST John with snail were higher than those without snail.It could be concluded that the increase of nutrition by snail in water could stimulate the growth of Hydrilla verticillata Royle and Elodea nuttalli ST John, because the metabolism of Bellamya sp.increased the nutrition of water and the primary productivity of aquatic plant were similar in three situations with the same experiment environment.

Xiuling Bai MA Jian-hua Yanli Sun Dexin Liu

Characterization of phosphorus (P) and its risk of loss in urban soils in Kaifeng City, Henan Province were studied through field sampling and laboratory experiments. The spatial distribution of P and the map of risk of loss were obtained using geostatistical and spatial analysis techniques. The P content in urban soils ranged from 400 to 1427 mg·kg-1, the proportions of inorganic P in total P ranged from 65% to 99%, and Olsen-P and CaCl2-P in soils were 3.41-115.03 mg·kg-1 and 0.01-9.40 mg·kg-1, respectively. The composition of P was consistent in different urban areas and P concentrations were higher in residential areas. Spatial variations in P concentrations in soils were significant; the concentrations of P in eastern Kaifeng City were higher than those in western Kaifeng and the highest concentrations were detected in central Kaifeng. Olsen-P can be used as an indicator of the leaching risk of soil P. The critical value of leaching P from the soil was 22.18 mg·kg-1 and the concentration of Olsen-P in 33.64% of urban soil samples exceeded the critical value. The highest risk of P loss existed in central Kaifeng City.

Dynamic changes of landscape pattern in Poyang Lake region over the recent 17 years

Soil and Environmental Sciences (2011)

Xiuling Bai

Based on the remote sensing images of 1989,1999 and 2006,dynamic changes of landscape pattern in Poyang Lake region were studied with ARCGIS and FRAGSTATS in recent 17 years.The result shows that the landscape pattern of Poyang Lake region had changed significantly due to both natural factors and human activities intervention.Analyzed from landscape level indexes,the landscape fragmentation was increasing,the different landscape patches tended to be uniform and scattered distributed,and the shapes of patches were becoming more complex and irregular.Patch types analysis indicates that the fragmentation degree in water bodies was increasing;the patches were becoming smaller,the shape of patches was more complex,and the hydraulic linkage between water patches was weakening.No evident changes were detected in grassland and forest which presented stable structure.Cropland was the dominant landscape;however,it became more irregular and fragmentized.Bottomland was influenced by hydrological condition and silt deposition more significantly.Its fragmentation degree was increasing during 1989—1999,and decreased in 1999—2006.Variation of construction land was most obvious with increasing fragmentation and patches linkage.Unused land was relative small,the fragmentation was decreasing,and the shape of patches was becoming simpler.

Environmental effect of sediment dredging in lake: Ⅲ. Influence of dredging on denitrification in sediments

Journal of Lake Sciences (2009)

Jicheng Zhong Guofeng Liu FAN Chengxin Xiuling Bai Bao Li

通过为期一年的疏浚模拟试验,在试验室培养疏浚与对照柱样,研究了底泥疏浚对沉积物反硝化过程的影响.沉积物反硝化速率的测定采用经典的乙炔抑制法,研究结果表明,在一年的试验周期内,疏浚和对照柱沉积物的反硝化速率分别为6.9-26.9nmol/(g·h)和21.6-102.7nmol/(g·h),除2006年的2月外的其他月份,疏浚沉积物的反硝化速率显著(P<0.05)低于未疏浚对照沉积物,同时还研究了环境因子对沉积物反硝化速率的影响,结果表明,疏浚和对照沉积物的反硝化速率都受温度的控制,硝态氮浓度是疏浚和对照沉积物反硝化速率的主要限制因子,有机碳对疏浚沉积物的反硝化速率有影响,但对未疏浚对照沉积物的反硝化速率没有影响.疏浚后短期内沉积物反硝化速率低于未疏浚对照沉积物,可看作是底泥疏浚在富营养华水体脱氮方面的一个负效应.;A laboratory experiment for studying the effects of sediment dredging on denitrification process was carried out through a one-year incubation of undredged sediments (control) and dredged sediment cores. Denitrification rates in the sediments were estimated by means of the acetylene blockage technique. During the experiments, the denitrification rates in the undredged and dredged sediments ranged from 21.6 to 102.7nmol/(g·h) and from 6.9 to 26.9nmol/(g·h), respectively. The denitrification rates in the undredged sediments were significantly higher (P < 0.05) than those in the dredged sediments throughout the incubation period, with an exception of February 2006. The relative importance of various environmental factors on denitrification was assessed, and the results indicated that denitrification rates in both undredged and dredged sediments were regulated by temperature controls. Nitrate was likely to be the key factor limiting denitrification rates in both undredged and dredged sediments. Organic carbon played some role in determining the denitrification rates in the dredged sediments, but not in the undredged sediments. Potential denitrification in the early dredged sediments couldn't reach a high rate as that in undredged sediments, which should be considered as a potential negative effect for nitrogen removal.
