Based on analyzing uncertainties when determining indicators system of ecosystem health assessment, an indicators system and a model for the evaluation of urban river ecosystem health was proposed. The model could offer the feasible and reliable base of decision-making for the river environment management.(4) An integrated method for land suitability evaluation based on geographic information systems under uncertainty was proposed.

The riv- er′s health status can be determined through a holistic appraisal of rivers and their surrounds.Five components of the rivers health include: water quality, aquatic life, physical form, hydrology and streamside zone.Many methods and criteria are available to assess the status of river ecosystem, and this review focuses on RIVPACS,AUSRIVAS,IBI,RCE,ISC,RHS and RHP, which are classified into the pred...

长输管道穿越河流后，针对河流岸堤的恢复，传统施工工艺多采用浆砌块石或混凝土等硬质材料，与原河道堤岸不和谐，破坏了自然河流的生物链，而生态型护岸既可防止水土流失，又可满足生态环境要求，是管道施工大开挖穿越河流后堤岸恢复的好方法。

Since the Late Pleistocene the coastal plain subsidence came into a quick phase, because the global eustasy superposed, as a result, the hydrothermal situation and relat...

在晚全新世河流造陆过程中，河流的沉积速率超过了海平面的上升速率，陆地才得以形成。在现代海岸带依然持续构造沉降、河流输沙减少、相对海平面上升的背景下，认识不同时间尺度环境变迁机制是极其必要的。

The choreography reflects this cycle. The riverwoman dances alone, her soft-shoe dance evoking the flow of the river. As she crosses the land, the earth, represented by the male dancer, awakens and bursts forth onto the stage. As the strength of the river builds, so dancers gather, signifying new life and energy, until the full Riverdance line swells to fill the stage as the river meets the sea. Then earth and river dance in harmony, as the water of life renews the land.

舞蹈依此循环为根基，女舞者独舞，她的软鞋舞著唤起河流流动，当她横跨土地，男舞者代表的地球苏醒，在舞台前方爆发出力量，河流的力量集结，舞者也集合，象徵新生命与力量，直到『大河之舞』所有舞者站成一线满溢舞台，正如河流汇入海洋，接著地球与河流合谐共舞，是生命泉源再生大地。

Deriving its name perhaps from the Sumerian word eden, meaning "plain"(or perhaps from a word denoting "pleasure"), Eden was supposedly located in the Near East, close to Israel, its precise locale narrowed by the position of four rivers that formed out of the river that flowed out of Eden and nourished the garden: the Pishon, the Gihon, the Trigris, and the Euphrates, rivers that would seem to place the garden in the fertile crescent.

它的名称源自闪族人词乐园，意思是&平原&（或也许来自话表示&快乐&），据推测乐园位于近东，在以色列附近，它的精确位置被河流的四条河流的位置所成形，此河流流经乐园和滋养花园：the Pishon， the Gihon， the Trigris，和幼发拉底河河流好象就是肥沃的新月形花园。

Based on the data analysis and numerical simulation, the Arctic sea ice climate variability was researched, the result were as following:(1) The analysis on the seasonal cycle of the Arctic Ocean and atmosphere showed that: The seasonal surface wind is somewhat trade wind like in some regions in the Arctic. The surface air temperature is robustly determined from the underlying environments such as sea ice and Greenland glaciers. In the sea ice region the precipitation rate is larger than that of evaporation. Furthermore, the Arctic Ocean hydrology is profoundly influenced by the surrounding rivers discharge. These are the decisive factors on the ocean salinity pattern. Sea ice flux through the Fram Strait is larger in winter than in summer. From the 40s in the 20th century on, the ice volume flux has an increasing trend. The Arctic rivers flood season is about the melt period, the winter rivers discharge has a significant increasing. Correlation analysis shows that 7 to 10 years is a characteristic time scale that rivers discharge leads Fram Strait ice volume export.(2) Considering 9 major arctic rivers, the Arctic Ocean circulation was simulated through BOM. The result shows that: The BOM can reproduce the main Arctic Ocean circulation pattern. The"Islandization"which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.

在资料分析和数值模拟的基础上，对北极海冰的气候变率进行了深入的研究，结果如下：(1)对北极地区大气和海洋季节循环特征的分析表明，气候平均风场在部分地区具有&信风&的性质；而气温场与海冰分布及格陵兰半岛冰原的下垫面特征有密切关系；在北极海冰区的降水量大于蒸发量，并且在全球大洋中北冰洋受到河流径流的影响最大，对北冰洋的盐度分布有决定作用；通过弗瑞姆海峡的海冰通量在冬半年大于夏半年，并且从20世纪40年代起，海冰的体积输送有增加趋势；北极河流的汛期主要在融化季节，冬季的河流流量有显著增加的趋势；相关分析表明7到10年是北极河流流量影响弗瑞姆海峡海冰体积输送的一个特征时间尺度；(2)采用BOM海洋模式对北冰洋海洋环流进行了模拟研究，在模式中考虑了北极9条主要河流的作用，结果表明该海洋模式可以较好模拟出北冰洋海洋环流的基本特征；多数大洋环流模式采用&北极岛化&的方法处理北极点，模拟结果表明&北极岛化&不仅影响到极点附近的海流，还会对相对较远的北大西洋海流造成影响，并可能通过大西洋的热盐环流对全球气候产生影响；(3)采用CSIM4海冰模式对北极海冰的气候态进行了模拟。
