群落环

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

First this paper analyzes and clarifies the statistical investigating data of winter migrant birds in Poyang lake in many years, and selects 44 samples on behalf of the main lake, this paper analyzes the birds community characteristic of abundant, variety, even, dominant and the meeting rate among the plant; this paper selects 10 environmental elements according to the reality of Poyang lake and selects the characteristic bird among rare plant, normal plant, wading bird, swimming bird etc, and.

本文首先通过对环鄱阳湖地区越冬候鸟多年调查统计数据的梳理和分析，筛选44个具有代表性主要湖泊作为样本，分析了各湖候鸟群落的丰富度、多样性、均匀性、优势度和种间相遇机率等特征；根据鄱阳湖实际选取10个环境因子，从稀有种、常见种、涉禽、游禽等方面结合选择具有代表性候鸟，进行了候鸟与湿地环境因子的相关关系分析。

The predominant genera in most sampling sites were Fragilaria, Navicula, Cymbella and Gomphonema, but the dominant Cyclotella only in the Long Lake.

脆杆藻属、舟形藻属、桥弯藻属和异极藻属常为优势属，只在长海是以小环藻属为单一优势属的群落。

The main species of the community were Isaria cateinannulata, I. farinosa and Beauveria bassiana.

该林区虫生真菌群落的主要成分是环链棒束孢、球孢白僵菌和粉棒束孢，虫生菌种类较少，较为单一。

It is involved in many aspects of organic matter decomposition, partial regulation of microbial activities, nutrient cycles and crumbly structure. Depending on their diet (saprophagous, phytophagous or predation), soil fauna is closely linked both to each other and to microorganisms, plants and soil.

本论文试图以土壤动物作为生物指标来评价土壤重金属污染，通过对重金属污染区(以浙江省富阳环山乡受污染的农田为例)土壤动物群落结构的调查和在室内设置一定的污染浓度梯度处理的盆栽试验两种方式研究了重金属污染对土壤动物群落的影响，主要结论如下： 1。

Take Fuzhou , this historical cultural city , as an example: According to the space heterogeneity of different dividing areas in the city and the green corridor structure of city (among them the green corridor passes through the other ring to take green, the Tenneco green land and garden green land of center district), the problems of how to draw the cleanness, wet and cold air around the surround into the center of city through the high green forest community which alleviate the tropical island effect and improve air quality and how to build the ecological view system of the city are discussed to make the city ecological view environment play its social role, the city will not develop at the cost of ecological view components , such as nature , history , and at the basis of expurgating, properly, the distillate of design in the history of the city humanity which would be a design language to stretch the nature, history and humanity view environments.

以福州这座历史文化名城为例：根据城市不同分区的空间异质性，贯通城市内的绿廊结构(其中绿廊穿越外环绿带、楔形绿地和中心区园林绿地)等探讨在城市化不断发展的过程中如何将城市周边清洁冷湿的空气经过高绿量的森林群落引入城市内部，缓解热岛效应，改善空气质量；以及如何通过城市的生态景观系统的营造使得城市的生态景观环境能够作为一个系统而充分发挥它的社会职能。通过对一个城市历史的系统解读使得城市化的发展过程不再是以自然、历史、人文等生态景观组成部分的破坏为代价，而是合理地提炼城市人文历史中积淀下来的部分，设计成为这个城市未来生态景观规划中的一个设计语汇，从更宽泛的角度延展这个城市的自然、历史和人文的景观环境。
