The integrated methodology for the assessment of estuarine trophic status (ASSETS), which was extended and refined from the United States National Estuarine Eutrophication Assessment (NEEA), is a multi-parameter assessment system and has been widely used in eutrophication assessment in estuarine and coastal waters. The ASSETS was applied to evaluate the trophic status of the Changjiang (Yangtze) River estuary, one of the largest estuaries in the world. The following main results were obtained: (i) The estuarine export potential is "moderate susceptibility" due to the "moderate" dilution potential and "moderate" flushing potential; (ii) The overall human influence (OHI) index classified the impact of nutrients in the system as "high" due to the high level of nutrient discharge by the river which channels anthropogenic impacts in the catchments to the estuarine system; (iii) The overall eutrophic condition (OEC) in the estuary was classified into the "high" category due to frequent occurrence of nuisance and toxic algal blooms in the mixing and seawater zones; (iv) Since the nutrient loadings (e.g., DIN) in the river is expected to continue to increase in the near future following the population increase and rapid economic growth throughout the drainage basin, the nutrient-related symptoms in the estuary are likely to substantially worsen, which leads to the "worsen high" category for the definition of future outlook (DFO). The combinations of the three components (i.e., OHI, OEC, and DFO) lead to an overall grade as "bad" for the trophic status in the Changjiang River estuary. 相似文献

以湿地植物香蒲为材料,在水平潜流人工湿地处理单元中,采用便携式LI-6400光合作用测定仪测定其成熟叶片净光合速率(Pn)日变化,研究其光合生理生态特性。结果表明:香蒲叶片净光合速率(Pn)日变化呈双峰曲线,主峰(22.0μmol.m-2.s-1)出现在9:00左右,次峰(16.9μmol.m-2.s-1)出现在15:00,光合"午休"现象明显,且非气孔限制是产生光合"午休"的主要原因。用逐步多元回归方法得到净光合速率日变化与主要生理生态因子的回归方程为:yPn=0.7692+29.7059 xGs-0.7689xTr+0.014 2 xPAR(复相关系数0.9563,显著水平P=0.0001;叶片净光合速率Pn,μmol.m-2.s-1;气孔导度Gs,mol.m-2.s-1;蒸腾速率Tr,mmol.m-2.s-1;光合有效辐射PAR,μmol.m-2.s-1)。偏相关分析和通径分析的结果表明Gs、Tr和PAR与Pn的日变化显著相关,是影响香蒲Pn的主要因子,影响大小的顺序为:Gs>PAR>Tr。香蒲叶片Pn-PAR的响应曲线方程为yPn=-5×10-6 xPAR 2+0.0207 xPAR-1.3728(相关系数0.9935,显著水平p=0.000 1),光补偿点、光饱和点和表观量子效率分别为32.9μmol.m-2.s-1、147 6μmol.m-2.s-1、0.023 3 mol.mol-1;Pn-CO2的响应曲线方程为yPn=-2×10-5 w(CO2)2+0.054 9 w(CO2)-1.44 4(相关系数0.9694,显著水平p=0.000 1;w(CO2)单位为μmol.mol-1),CO2补偿点、CO2饱和点和羧化效率分别为23.7μmol.mol-1、621.4μmol.mol-1和0.0768 mol.m-2.s-1。 相似文献

In this paper,
the feed value of the larva of pinc tada fucata in the production of the fry of tiger
shrimp, Penaeus monodon, were studied. The mollusk larva were gained by inducing spawning
or artificial f ertilization of the eggs from living pearl oysters or discarded oyster
cadaver. Comparisons of the nutrition values of oyster larva and brine shrimp (Artemia
nauplii) for the larvae of Penaeus monodon were carried out. The results a re clear that
the zoaea survival rate in 5 days of tiger shrimp fed with oyster larva was higher than
with larva of brine shrimp the former was 69.8%～71.5% an d later was 64.0%～67.4%, the final survival rate of shrimp fry fed with
larva o f brine shrimp was 49.8%, the highest in the three testing groups. 相似文献

空气质量关系到人民的身心健康,各大城市的PM2.5值(即空气中所含直径小于或等于2.5微米的颗粒物数量)已经成为当地居民最为关注的重要话题之一.2013年6月19日,环境保护部有关负责人向媒体发布了2013年5月份京津冀等74个城市空气质量状况:其中,石家庄、唐山、济南、郑州、北京和天津等地的空气质量较差;海口、惠州、福州、深圳、东莞和厦门等空气质量相对较好.结合历年来环保部等部门的公布数据,我们发现:城市空气质量的好坏,似乎与该城市的产生时间具有某种"神秘的联系"——城市出现的时间越早(我们不妨称为"古代城市"),其空气质量越差;形成时间较晚的城市(暂且称为"近现代城市"),其空气质量就要好一些. 相似文献

Restriction site amplified polymorphism (RSAP) was used, for the first time, to analyze the genetic structure and diversity of four, mainly cultivated, varieties of the brown alga, Saccharina japonica. Eighty-eight samples from varieties "Rongfu", "Fujian", "Ailunwan" and "Shengchanzhong" were used for the genetic analyses. One hundred and ninety-eight bands were obtained using eight combinations of primers. One hundred and ninety-one (96.46%) were polymorphic bands. Nei’s genetic diversity was 0.360, and the coefficient of genetic differentiation was 0.357. No inbreeding-type recession was found in the four brown alga varieties and the results of the "Ailunwan" variety using samples from 2 years showed that the variety was becoming less diverse during the selection inherent in the breeding program. Genetic diversity and cluster analyses results were consistent with these genetic relationships. The results show the RSAP method is suitable for genetic analysis. Continuous inbreeding and selection could reduce the genetic diversity effectively; therefore periodical supervision is required. 相似文献

松辽盆地北部发育典型非常规致密砂岩油,基于"甜点"储层地震预测实际需求,采用面向储层预测的测井数据评价、岩石物理扰动模拟和地震数据刻度技术,分析该地区致密砂岩储层地震岩石物理规律.结果表明:研究区致密孔隙介质的弹性特征变化主要受岩性和物性控制,岩性控制作用更大,孔隙流体影响小;利用纵波阻抗和纵横波速度比(或泊松比)双元弹性参数交会可识别"甜点"储层;基于岩石物理刻度的叠前AVO反演是实现"甜点"储层地震预测的有效途径.研究区水平井钻探实例证明,地震岩石物理分析在基础资料认识、优化,以及"甜点"储层地震预测中具有重要作用. 相似文献
