The research indicate that the aquatic ecosystem of Wuhan city lakes now is: elementary production and consumption keep high amount, and accumulate in the water bodies, then the benthon ,so much as fish's community to decline seriously, cause the main nutrients cycle and energy circulation in the system is obstructed, that means the "elementary production-elementary consumption-advanced consumption" replaced by the "elementary production-elementary consumption-analyze by itself – reproduction", this circulation of the the nutrients is unfavorable to the system.

生态系统结构研究表明武汉市湖泊水生生态系统目前所处状态：初级生产和初级消费维持较高生产量和现存量，在水体中积累，而较高层次的底栖生物乃致鱼类群落严重衰退，导致系统中主要物质和能量循环：初级生产—初级消费—高级消费受阻，代之而起的是初级生产、初级消费—自行分解—再生产的循环，不利于系统中物质转移。

At high elevation above 1800 m, Betula ermanii was the only species that could form a mono-dominant community.

随着海拔的上升，进入主林层的树种越来越少，海拔高于1800m时，岳桦是唯一可以成为建群种的树种，形成了单优势种群落。

At the same time, the effect of sulfate on the anaerobic treatment, and how to avoid sulfate bacteria restraining methane bacteria were specially discussed. Through the studies of microbe bionomic of anaerobic, the sludge training, characters and model of granule sludge were deeply comprehended.

Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.

通过将化学分析、毒性鉴定和底栖群落结构变化三基元集成为一体的三轴图和相应的响应信息判断矩阵，基于现场生物响应的沉积物质量基准能较为清晰地指示乐安江流域表层沉积物中重金属污染的相对程度和分布模式，体现底栖生物对沉积物重金属污染的剂量-响应关系，为进一步制订该区域沉积质量管理标准、开展后续的污染治理与恢复工程提供技术保证和科学依据

In this paper, we studied community stability, forage quality and yield character about the mixed-sowing of Medicago sativa and Bromus intermis from 2003 to 2004 and using Factor Analysis, Principal Components Analysis methods and getting the yield forecast model with linear regress multianalysis method. The study provided theoretical foundation for establishing high yield and good quality artifical pasture.

本试验以紫花苜蓿与无芒雀麦为供试材料，于 2003~2004 年对 6 个不同混播处理的群落稳定性、牧草产量及质量性状进行了系统的研究，并运用因子分析法、主成分分析法和多元线性回归的方法，建立了产量预测预报模型，结合经济效益评价和提高土壤肥力的因素，确立最佳混播处理。

The results indicated that the combination of Bromus inermis plus Medicago sativa (T6) and that of M.sativa plus Poa pratensis (T5) performed the best among all six trials, in respect to their forage yield, community stability and capability in competition with weeds.

结果表明，混播组合T6和T5(紫花苜蓿-草地早熟禾型)在群落稳定性及抗杂草的竞争力等方面表现均佳。

The results showed that the niche breath of 9 species are wide, and that the species are pioneer in mine spoil Nanjing Mufu Mountains, the niche breath of Broussonetia papyrifera is wide, but the niche overlap with other species is little.

结果表明：研究的9个树种的生态位总体比较接近，都有比较宽的生态位，从群落形成的时间分析，这些树种是在矿区废弃地上的先锋树种，对废弃地有较强的适应能力。
