1.1.2 赣江 Ganjiang river

赣江南北流贯江西，是江西省最大的河流，古称扬汉(杨汉)、湖汉等，流域面积8.16万平方公里，占江西省面积的51%。以万安、新干为界，分为上游、中游、下游三段。

东源出自石城的武夷山黄竹岭，称绵水，流经瑞金，在会昌与湘水(江西)汇合，称贡水，流经于都、赣县、章贡区，为赣江正源。西源章水发源于崇义县聂都山张柴洞，流经大余、上犹、南康、赣县、章早期赣江贡区。

章、贡两水在赣州章贡区八境台汇合后始称赣江。曲折北流，经万安、泰和、吉安县、吉州区、青原区、吉水、峡江、新干、樟树市、丰城到南昌市新建县、南昌县，分四支注入鄱阳湖。赣州以上为上游，山地纵横，支流众多，主要有湘水、濂江、梅江、平江、桃江、上犹江等，分别汇入章水和贡水。赣州至新干为中游。赣州至万安段，由于河流切割遂犹山地，多峡谷和险滩急流，万安水电站建成后，险滩多已消失;万安以下，河流进入吉泰盆地，河面渐宽，水势和缓，东西两岸有孤江、遂川江、蜀水、禾水、泷水等较大支流汇入，水量大增;吉水到新干段，切穿武功山余脉，形成一较长的峡谷带。新干以下为下游，山势渐退，江面逐渐开阔，水流平缓。有袁水和锦江汇入。

在古代，河流是交通运输的主要载体，赣江航运网络的构建，促进了南昌地区信息流、物资流、文化流的形成。赣江从万安的良口入境到新干的三湖出境，全长260多里，河床较宽，水势平缓，利于航行。许多条支流通往赣江，为人们提供了舟楫之便，灌溉之利。自秦至清2000多年来，赣江是沟通祖国南北交通的大动脉，一直称作黄金水道。南来北往舟楫穿行，帆樯竞发，官宦商贾云集两岸，南昌的物产顺赣江流入长江发至各方，溯流运往粤桂;八方的信息和物品也经赣江散至南昌大地。赣江及其主要支流旁建成一串城镇，拱卫南昌城。许许多多的儒士雅客，也在这条河上航行，写下脍炙人口的诗文。

效果图（三）

Gan river north and south flow penetration of jiangxi province, is one of the largest rivers in jiangxi province, the ancient call of han han (Yang Han), lake, etc., the basin area of 8.16 square kilometers, accounting for 51% of the area in jiangxi province. To vie, new dry is bounded, divided into upstream, midstream and downstream of the three sections.

Dongyuan wuyishan whangee from shicheng ridge, according to cotton, water flows through the ruijin, in making-friends merges with hunan water (jiangxi), said gong, water flows through, yudu county, it is the source for the gan. West chapter source water from worship in yixian nie are mountain wood hole, flows through DaYu, chapter Jude, bamboo-shack, county, early on the gan gong area.

Chapter two water in ganzhou, gong it eight said after Taiwan joined the gan. Twists and turns north flow, the vie, taihe, JiAnXian, obviously, QingYuan area, auspicious water, XiaJiang, new dry, ZhangShuShi, fengcheng city to nanchang, xinjian county, NaChangXian points four injection of poyang lake. Ganzhou above for upstream, mountain and numerous tributaries, xiang water main, song jiang, meijiang, at pingkiang, taojiang, of jiang, such as chapter respectively into the water and water gong. Ganzhou to new dry to middle. Ganzhou to vie for, because the river cutting hence hill country of judah, canyon and rapids rapids, after the completion of wanan hydropower station, dangerous shoals has disappeared; Wanan, rivers into jitai basin, the river grows wider, the waters gentle, solitary river on both sides of things, so familiar, shu water, grain and water Long tributary import, water. Water to the new dry period, cut wear wugong mountain -odd arteries, forming a long valley belt. A fading under new dry for downstream, to the mountain, river gradually open, the water gently. There are water and jinjiang into yuan.

Is the main carrier of the transportation in ancient times, rivers, the gan shipping network construction, promote the nanchang area information flow, the formation of cash-flow, cultural flows. Gan of wanan good entry into the new dry lakes exit, total length of more than 260, the river is wide, the water gently, sailing. To many of the tributary of the gan, provides people with the boat that irrigation. From qin dynasty to qing dynasty for more than 2000 years, the gan is the motherland the north-south traffic artery communication, has been called the golden waterway. Always on the boat, boat race, senators were merchants gathered on both sides of the nanchang product along the gan river flows into the Yangtze river to the parties, go to YueGui; Eight side information and items via the gan scattered to nanchang also. Beside the river and its main tributaries built a string of towns, vault of nanchang city. Many Confucian scholar yake, sailing on the river, also wrote popular poems.

1.1.3鄱阳湖 Poyang lake

鄱阳湖是中国第一大淡水湖，位于江西省北部，距南昌市东北部50公里。鄱阳湖上承赣、抚、信、饶、修五河之水，下接我国第一大河——长江。在正常的水位情况下，鄱阳湖面积有3914平方公里，容积达300亿立方米。它每年流入长江的水量超过黄、淮、海三河水量的总和。鄱阳湖在九江的水面约20万公顷，流域有都昌、湖口、星子、永修、德安、庐山区等六个县(区)。平均水深8.4米，最深处能达到30米。但近些年由于三峡大坝等各种原因， 鄱阳湖天然水产资源大幅减少，鄱阳湖作为中国最大的淡水湖，不简单是渔业的收益问题，最重要的是中国乃至全球的环境问题。

Poyang lake is the first largest fresh water lake in China, is located in the north of jiangxi province, 50 kilometers away from nanchang city northeast. Poyang lake deck gan, fondle, letter, rao, area of water, the first river, the Yangtze river in China. Under the condition of normal water level, the poyang lake area of 3914 square kilometers, the volume of 30 billion cubic meters. It flows into the Yangtze river water every year more than yellow, huai and hai sanhe water combined. In Jiujiang about 200000 hectares, the surface of the poyang lake basin are duchang, 13, the planetesimals, permanent fix, nickelodeon, Lushan mountain area and so on six counties (districts). The deepest 8.4 meters, the average water depth can reach 30 meters. But in recent years, due to various reasons such as the three gorges dam, the poyang lake natural aquatic resources dropped sharply, as China's largest freshwater lake poyang lake, is not simple fishing revenue problem, the most important thing is that Chinese and global environmental problems.

鄱阳湖水系环境现状 Poyang lake water environment status quo

一、水环境现状 Present situation of water environment

鄱阳湖地区多年平均年降水量1574.6mm，年径流深719.0mm，年蒸发量1080mm。全区多年平均降水量总量610.3亿m3，产水量278.7亿m3。鄱阳湖地区地下水资源的年总量为47.0亿m3，约为本区地表径流量的16.9%。但分布不均，可供国民经济建设规划的可开采地下水资源年总量为23.6亿m3。鄱阳湖多年平均由湖口入长江的水量145.7亿m3，赣、抚、信、饶、修5条河入湖水量126.5亿m3，占入长江水量的86.8%。一般每年的2～6月份，5条河入湖水量大于入江水量，是鄱阳湖的蓄水期，总蓄水量17.8亿m3。7月至次年1月均为鄱阳湖主要排水期，多年平均入湖、入江水量均为145.7亿m3，达到平衡。最高水位多出现在5~7月，入江最大流量在6~9月。

Poyang lake region for many years the average annual rainfall 1574.6 mm, annual runoff depth of 719.0 mm, annual evaporation is 1080 mm. Regional years of average rainfall total 61.03 billion m3, 27.87 billion m3 water rate. The groundwater resources in poyang lake area is 4.7 billion m3, about 16.9% of the surface runoff in this area. But uneven distribution, for the national economic construction planning of recoverable groundwater resource in total amount is 2.36 billion m3. Poyang lake for years by the hukou in the Yangtze river water of an average of 14.57 billion m3, gan, caresses, letter, rao, five rivers into the lake water quantity of 12.65 billion m3, accounting for 86.8% of the water into the Yangtze river. General 2 ~ 6 months a year, five rivers into the lake water quantity is greater than the water into the river, is the storage period of poyang lake, the total storage capacity of 1.78 billion m3. July to the following year, 1 month for poyang lake main drainage period, many years into the lake, the water into the river are an average of 14.57 billion m3, equilibrium. Highest level in 5 to 7 months, more into the river's maximum flow in 6 ~ 9 month.

二、水质污染现状 Water pollution status quo

根据近5年鄱阳湖九江水域2个监测点位的水质监测数据和平均综合污染指数系统分析，水质均达到Ⅲ类水体水质标准。监测数据显示除07年没有污染物超标外，其余年份总磷、总氮均出现超标现象，说明鄱阳湖水质呈现有机污染特征。其中，枯水期污染状况重于丰水期，丰水期又重于平水期。主要污染物为总磷、总氮、高锰酸盐指数、生化需氧量，占总负荷的78.14%，其它污染物占21.86%。综合营养状态指数法进行的水体富营养化分析显示，湖区水体为中营养状态。水质总体分析结果：鄱阳湖九江区域水质状况良好，达到Ⅲ类水体水质标准，湖区水体富营养化程度为中营养状态。

鄱阳湖地区自然条件复杂，植被类型多样。但鄱阳湖区森林覆盖率较低(低于江西省平均水平)。天然森林植被主要是次生林。鄱阳湖湿地植被面积2262km ，自岸向湖心，植被呈不规则的环带状分布。近50多年来，因受人类和自然因素干扰，湿地植被带完整性遭破坏，

湿地植被分布面积逐年减少，生物量逐年下降。鄱阳湖区现有沙化荒地267km.鄱阳湖动物资源也非常丰富，每年到鄱阳湖湿地越冬的鸟类约有三百余种，几十万只;是迄今发现的世界上最大越冬白鹤群体所在地，白鹤种群约占全球的98%以上;也是迄今发现的世界上最大的鸿雁群体所在地，鸿雁数量达3万只以上;是全国最大淡水水产养殖水域，有鱼类122种、浮游植物50种;是长江一些珍贵鱼类漫游、产卵与育肥的场所。

phosphorus, total nitrogen, permanganate index, bod, accounting for 78.14% of the total load, other pollutants accounted for 21.86%. Comprehensive nutrition state index method, according to the analysis of the eutrophication of the lake water body for nutrition condition. Overall water quality analysis results: jiujiang area poyang lake water quality in good condition, achieve Ⅲ class water quality standard, the level of lake eutrophication in nutritional status.

Poyang lake region complex natural conditions, vegetation types and varied. But PoYangHuOu forest coverage rate is low (less than average) in jiangxi province. Natural forest vegetation is mainly secondary forest. Poyang lake wetland vegetation area of about 2262 km from shore to the middle, the vegetation distribution is irregular band. Nearly 5 o years, due to the interference by human and natural factors, the wetland vegetation destruction with integrity,

Wetland vegetation distribution area is reducing year by year, biomass decline year by year. PoYangHuOu existing desertification land 267 km. The poyang lake animal resources are very rich, every year at the poyang lake wetland and about more than three hundred kinds of birds in winter, hundreds of thousands of thousands; Is the world's largest ever found in wintering crane group is located, crane population accounts for more than 98% of the world; Is the world's largest ever found in swan goose group is located, the swan goose can number more than 30000; Is the largest freshwater aquaculture waters, 122 fish

A, 50 of phytoplankton. Is the changjiang river and some precious fish roaming, spawning fattening.
