长江中下游湿地自然保护区有效管理的思考 Effective Management of Wetland Nature Reserves in Middle and Lower Reaches of Yangtze River 1.长江中下游湿地保护的重要性 the significance of protecting wetlands in Middle and Lower Reaches of Yangtze River 一、干流江面宽展曲折，支流密布，淡水流量大 Wide mainstream ，so many anabranches and high flux of freshwater 二、密集分布着通江、浅水、变化剧烈的湖泊群 Densely distributes shallow lakes which connect rivers and change severely 三、河漫滩、湖滨、海滨沼泽发育良好 Everglades are well developed at shore of rivers, lakes and sea (1)特有的流域湿地结构 proper structure of wetlands 这样的湿地系统结构在地球同纬度地区是唯一的！ This structure is one and only in the same latitude on the earth! the significance of protecting wetlands in Middle and Lower Reaches of Yangtze River 1.长江中下游湿地保护的重要性 (2)维护丰富的生物多样性 conserving profuse biodiversity 一、独特的草型湖泊 初级生产力高 Distinctive grass-grown lakes，High primary productivity 二、水生生物多样性高 High aquatic biodiversity 三、大量珍稀特有种 Many rare endemic species 1.长江中下游湿地保护的重要性 the significance of protecting wetlands in Middle and Lower Reaches of Yangtze River (3)保障流域生态安全 safeguarding ecological security 调蓄洪水 regulating and storing floods 供应优质水源,净化水体 providing high-quality water, purifying water 调节气候, 净化空气 regulating climate, purifying air 是强大碳汇 being significant carbon sink 1.长江中下游湿地保护的重要性 the significance of protecting wetlands in Middle and Lower Reaches of Yangtze River 第一产业（农、渔业） primary industry (4)与社会经济发展联系紧密 tightly connect with the social-economic development 第二产业（运输业） secondary industry 第三产业（城市供水，旅游业） tertiary industry 2.长江中下游湿地自然保护区现状 the status quo of wetland nature reserves in Middle and Lower Reaches of Yangtze River (1)最近一次官方统计（2008.12） latest official statistic（Oct, 2008） 类型type 湿地自然保护区数量/个 quantity 　 湿地自然保护区面积/hm2 area N P Ci Co T N P Ci Co T W 2 11 4 17 34 106047 516378 141260 144025 907710 A 12 23 1 17 53 447007 205666 1560 66166 720399 V 0 0 1 1 2 0 0 0 99 99 T 14 34 6 35 89 553054 722044 142820 21029
