     The runoff volumns of the other six rivers are between 0.19 and 0.23 and the extreme value is between 1.85 and 2.42 except the Toudao ditch,whose runoff volumn is 0.44 and whose extreme value is 4.42.Most of the Xinjiang rivers has bigger runoff volumn than that of the 1990s.
     从径流量的Cv值看,除头道沟为0 44,极值比4 42较大外,其它河流的Cv值均在0 19—0 23间、极值比在1 85—2 42间。 同时,新疆大多数河流径流量90年代后有明显增多的趋势。

According to the relationship between the linking of an interfluve of two Rivers and a network of stream system, this paper analyzes the significance of the canal crossing the watershed between the Qiantangjiang River of Zhejiang and the Xinjiang River of Jiangxi. Then, the physiographic conditions in the selected area are discussed as fallows.1. Topographically, according to the principle that the relief must be low and the selected line must be short, there are there lines to be selected in thewater-shed area between the Qiantangjiang River and the Xinjiang River i.e. the North Line, the Centre Line and the south Line, in which the canal of the North Line will be 45km long and 1025m high, the Centre Line 46km long and 96. 86 mhigh, and the South Line 35km long and 105.8m high.2. According to the engineering geological conditions it seems that the Centre Line is best , the North Line is second, and the South Line is bad3. As for the form of the canal, it should be taken as areservior shape of river channel.For its water sources, apart from using small reservoir built along the canal, it is necessary in addition to develop such as drainage area of the Ji-nshaxi and Shangshangang,or Jiangshangang, and to build or extend some keser-rvoirs, i.e. "Giy1" and " Jixi" , or "Baishuikeng" Reservoirs, and so on.Las, taccording to united scheme of the stair channel of the two rivers, three distinct schemes (including the linking-up opposite each other of both the beginning point and the end poin,tthe contour penetration, and many stairs of the Centre Line).are proposed.It is considered that in them the scheme of linking-up opposite each other of both the beginning point and the end point in the Centre Line is more reasonable through synthetic comparisoni, i.e. investment, moving hereafter, and engineering construction compavisons

Xinjiang river is one of the five main rivers in Jiangxi Province. The length of the main stream is 312 kilometres. Total of 49 species, belonging to 33 genera and 25 families, have been collected. Among them, Vallisneria spiralis distributed most widely;Hydrilla verticillata followed next.

本文列出了信江现有水生植物25科33属49种的名录;阐述了植被类型及分布,并对其8个主要群落的有关生态问题进行了分析.文中用断面计算法估算出信江水生植被的单位面积生物量和全河总生物量,最后就其植被特点进行了分析和讨论.

Based upon the monthly-obtained data on water quality from 1981 to 1990 in Poyang Lake district, the status quo and trend of water quality in Poyang Lake are comprehensively analysed. The results are: (1) BOD5 surpluses by 2. 1 % - 22. 2 % in 1990 in some inlets and near some stations of the lake area; TP surpluses by 9. 1 % - 29. 3 % at all stations except the esturies of the Gangjiang Rever (West Branch) and Fuhe River; (2) As, volatile phenol and TP are the main pollutants; (3) the natural conditions...

根据鄱阳湖1990年监测资料,对水质污染现状进行分析,同时利用1981—1990年资料,分析了水质变化趋势。分析表明:湖体、河口水质均属较清洁水或尚清洁水。但是,随着入湖污染负荷量的增加,湖区水体污染呈上升趋势,宜引起有关部门高度重视。
