The wetland in Dongting I.ake region is the largest lacustrine wetland in China, covering anarea of 8. 77.105 h.2. It can be divided into three classes: open waters, seasonal flood basins andflat, shallow marshes. Due to neglecting environmental management and ecological construction,soil and wate'r erosion in the upper and middle reaches of Yangtze River, the deposition of sediment in lakes, reclaiming land from lake marshes on large scale, irrational distribution of agriculture and improper cropping system at high water level zone, the regulating capacity for floods wasdescending, flood water level rose and flood period was prolonged. With the large scale exploitation of wetland certain harmful influence on the ecological environment began to manifest itself, i.e. the aggravation of the disasters of water -- logging; low comprehensive utilization; the exasperation of the contradiction between agriculture, fish -- farming, water storage and inland navigation; and the degradation of ecological functions. In order to utilize and protect wetland rationally, the following measures should be taken: (1 ) controlling the scale of wetland reclamation andmaking great efforts to construct high -- efficiency and multi -- purpose wetland ecosystem. Thereclamation without floodwater storage should be readjusted into new land use with flood storageproject. Settlement should be moved to small town. Cultivation and planning can be carried out innormal year. It will be used for storing water while a catastrophic flood takes place. Some fieldswhich are hindrance for flood flow should merge properly with lakes for fish culture. (2) To adjust allocation of agriculture and cropping system. (3 ) To breed and popularize submergence -- tolerant rice variety. (4 )strengthening wetland comprehensive management. According to the principles of ecological engineering and previous practices, 9 comprehensive utilization models which aresuitable to open waters, seasonal flood basins and flat, shallow marshes are put forward.

地处长江中游的洞庭湖是一个承纳湘、资、沉、澄四水和吞吐长江的洪道型湖泊,在其特殊的地理环境与碟形盆地圈带状景观结构控制下,形成了以敞水带、季节性淹没带、渍水低地为主的我国最大的湖泊地区湿地景观,湿地总面积87.70万hm2。由于湖区发展过程中没有协调好人地、人湖关系,中上游干支流水土流失加剧、湖泊泥沙淤积与过度围湖垦殖、高水位地段农业布局与种植制度不合理等人为因素导致湿地面积减少、调蓄能力下降,洪水位抬升、外洪内涝交织,灾害频率上升、资源过度利用与闲置并存等问题。为了合理开发湿地资源,必须强化湿地整体管理,适度退田还湖还蓄(洪区),调整农业布局与种植制度,建设复合高效湿地生态系统。进行适应洪涝灾害发生规律的避洪、耐渍型生态设计,建立适应浅水水体、湖洲和低湖渍害田的复合高效生态工程模式。

The wetland in Dongting Lake region covers an area of 877×10 3 ha,which can be divided into three types: open fresh waters, seasonally flooded basins and flats, shallow fresh marshes. Due to soil erosion in the upper and middle reaches of the Yangtze, the deposition of sediment in the lake, reclaiming land from lake marshes on large scale, irrational distribution of agriculture and improper cropping system at high water level zone, the regulating capacity of the lake for floods is descending,the flood water level rises,and the flood period is prolonged. The large scale development of wetland has made some harmful influence on the ecological environment,resulting in the aggravation of the flood and water logging of disasters, the exasperation of the contradiction between agriculture, fish farming, water storage and inland navigation, and the degradation of ecological environment. In order to utilize and protect wetland rationally, the following measures are suggested: 1) controlling the scale of wetland reclamation,constructing high efficiency wetland ecosystem,and appropricately enlarging the area for flood water storage,while reducing the area of rice fields;2) adjusting allocation of agriculture and cropping systems. 3) breeding and popularizing soak resistant varieties of rice.4)strengthening comprehensive management of the wetland.Nine models for comprehensive utilization of open fresh waters, seasonally flooded basins and flats, shallow fresh marshes are put forward.

地处长江中游的洞庭湖是一个承纳湘、资、沅、澧四水和吞吐长江的洪道型湖泊。在其特殊的地理环境与碟形盆地圈带状景观结构控制下,形成了以敞水带、季节性淹没带、渍水低地为主的我国最大的湖泊地区湿地景观,湿地总面积8770×104hm2。由于湖区发展过程中没有协调好人地、人湖关系,中上游干支流水土流失加剧、湖泊泥沙淤积与过度围湖垦殖、高水位地段农业布局与种植制度不合理等人为因素导致湿地面积减少,调蓄能力下降,洪水位抬升,外洪内涝交织,灾害频率上升,资源过度利用与闲置并存等问题。为了合理开发湿地资源,必须强化湿地整体管理,控制湿地开发规模,适度退田还湖还蓄(洪区),调整农业布局与种植制度,走集约持续发展之路,建设复合高效湿地生态系统。进行适应洪涝灾害发生规律的避洪、耐渍型生态设计,建立复合高效生态工程模式。

Based on the water area character in Dongting Lake wetland, the water origin resources condition is analyzed. The water area agriculture development model of the lake and estuarine branch, the wetland plain and the low hilly zone based the character of the concentric circle shape in Dongting Lake is studied to reach the goal of protecting wetland water area ecological environment.

洞庭湖区湿地水域有3种类型:湖盆中心敞水带、滨湖季节性淹没带和湖区外环渍水低地带,呈碟形盆地圈带状立体景观结构的特征,即同心环带状:湖盆中心带、湖滨中环带、外环带。该湿地动植物资源、水资源十分丰富,有辽阔的湖洲滩地。分析洞庭湖湿地水域经济发展存在的问题:湿地面积减少,蓄水能力及调蓄洪水能力减弱,洪涝灾害频繁;生态功能退化,生物多样性受损;水质污染严重,水产品质量下降。鉴于洞庭湖湿地复杂的生态系统和丰富多样的水域资源及现存问题,提出分别适应洞庭湖区3种类型湿地水域的生态农业开发模式,以期达到保护湖区湿地水域生态环境、湿地资源持续利用、生态效益与经济效益并重的目的。
