Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement. The water requirement for transport is 80 × 108-120 × 108 m3 per year if the bankfull discharge carries the largest sediment and contaminant load over a long period of time. The base ecological flows in non-flood season at Huayuankou and Lijin stations are 80 × 108-100×108 m3 and 50 × 108-60 × 108 m3, respectively.

通过分析黄河下游1958～2000年实测生态可用水，探讨生态需水量内涵，根据黄河特殊性及黄河生态需水量的研究现状，将维持和保护河流功能的黄河下游生态需水量分为汛期输运水量和非汛期生态基流量，在平滩流量输运能力最强的前提下，估算黄河下游汛期输运水量为80～120亿m3，根据实测资料估算作为黄河下游水量控制断面花园口水文站和作为河口地区水量控制断面利津水文站的非汛期生态基分别为80～100亿m3和50～60亿m3。

The paper introduces the general situation, the cycle situation of ecology network, the establishment of ecology index, the service situation of management information and so on about 4 national exemplificative Eco-Industrial Park containing GUIGANG EIP. All of these introductions are based on bulks of collected and arranged associated informations, combined with domestic practical situation.

本论文在大量收集、整理生态工业园的相关信息基础上，结合国内实际情况，详细介绍了贵港生态工业园区等4个国家示范生态工业园区的概况、生态网络循环状况、生态指标建立和管理信息服务状况等内容，经过详尽的分析得出目前生态工业园区建设中存在的问题。

Niche which many ecologists have become interested in is an important concept in ecology. The main definitions of niche are the habitat niche of Grinnell (1917), the functional niche of Elton (1933) and the hypervolume niche of Hutchinson (1957) whose concept has by far the largest influence on niche.

生态位是生态学的一个重要概念，许多生态学家都对生态位下了定义，主要有Grinnell(1917)的生境生态位，Elton(1933)的功能生态位，Hutchinson(1957)的超体积生态位，尤以Hutchinson的&超体积生态位&影响为大。

The results showed that the height niche breadth of Litsea subcoriacea and Cinnamomum chekiangense in gaps and in non-gaps were the biggest. The height niche overlaps were greater between those species that had similar biological and ecological characteristics, and vice versa.

结果表明：桂北木姜子和浙江桂在林隙内外都占有较高的生态位宽度；生物学特性和生态学特性接近的树种高度生态位重叠较大，反之则较小；在林隙内，山矾和薄叶山矾的高度生态位重叠最大，而桂北木姜子和黄瑞木、尖叶水丝梨，浙江桂和尖叶水丝梨的高度生态位重叠较小；在非林隙内，山矾和黄瑞木的高度生态位重叠最大，桂北木姜子和尖叶水丝梨、黄瑞木的高度生态位重叠较小。

Instead, they were able to find a certain region which was most suitable for living in the natural ecological system in the process of cultural building, and then to build and protect the national habitat which belonged to their own nationality according to their understanding of their nationality's culture.the protection of ecologic was mainly realized by cultural restraint and balance, it had the features of unconsciousness, remoteness ,passivism and regionalism.exploring the features and functions of this kind of protection is good for deepening the awareness of national habitat and offering predecessor's experience and lessons to nowaday ecological protection

古代民族由于所处时空域的限制，不可能全面认识自然生态系统并自觉直接维护生态环境，而是在文化建构的过程中从所处的自然生态系统内人为地分割出一个最适合于本民族生息的区域，按照本民族文化的理解去建构并直接维护本民族特有的民族生境。对生态环境的维护，主要是通过文化制衡来实现的，它具有无意识性、间接性、被动性和区域性。探讨这种生态维护的特点及功效，有助于深化对民族生境的认识并为今天的生态维护提供前人的经验教训。

With the parameters from published literature and experiments, we conducted forward analysis to compare soil organic carbon, carbon sequestration rate and soil total nitrogen dynamics of four different ecosystem types bare ground, Scirpus mariqueter, Phragmites australis, S.

通过构建九段沙生态系统碳氮模型并结合实测数据比较了互花米草入侵后生态系统土壤有机碳储量、碳封存速率和土壤总氮与其在土著占优势的3类生态系统（裸地、海三棱藨草、芦苇）中的差异，结果表明互花米草入侵的生态系统，其土壤有机碳储量高于裸地和海三棱藨草生态系统，却低于芦苇生态系统。
