All the human activities of overuse of runoff, overdevelopment of hydropower, inappropriate regulation and control of floods and sediment, overmuch discharge of polluted water to the river and the changes of habitat environment of key species would harm the health of a river.

人类过多抽取河川径流和开发水电、不当地调控洪水和泥沙、过多向河流排污和改变关键物种栖息地环境的活动，均会对河流健康造成伤害。

The pap suggests tha t not all of refluent tributary play important role in river evolution.

尤其是逆插支流的演变，对主干河流是否掉向，意义重大，但不是所有逆插支流都对指示主干河流掉向有意义。

Combined with granularity analysis, characteristics of fluvial sand body morphology and sinuosity of the river, the sedimentation of Guan(1+2) sand sets was defined on the basis of the stratigraphic subdivision and correlation.

在地层划分和对比的基础上，结合粒度分析、河流砂体形态、河流曲度等特征，对孤岛油田馆（1+2）砂层组沉积模式进行了研究。

The hydrological, geomorphological and sedimentological characteristics of some anastomosing river s have been revealed.

网状河流是受到人们关注的新型冲积河流，其水文特征、地貌特征和沉积特征已经不同程度地被揭示。

Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

Base of it, the relationship between ecosystem and factors mentioned above is discussed and the frame for downstream riverine ecosystem model is presented.

这是河流动力学与河流生态学相融合的初步尝试。

The water swelled most of the area's lakes, small rivers, creeks and streams.

水膨胀该地区的湖泊，小河流，小溪和河流最。

A fearful man, all in coarse grey, with a great iron on his leg. A man with no hat, and with broken shoes, and with an old rag tied round his head.
