摘　　要：利用时间序列以及产业结构研究中广泛使用的库兹涅茨产业结构变动幅度、产业结构变动速率分析1996—2008年间鄱阳湖湖滨地区的渔业产量和结构变化特征。研究结果表明,湖滨地区的渔业总产量以每年6%的增长率稳定增加,其中养殖产量为增长的主动力,天然捕捞量稳中有降。受自然条件影响,湖滨地区渔业产量区域差异明显,南昌县因其得天独厚的自然条件,其渔业产量居各县市之首,占到鄱阳湖湖滨地区总产量1/6以上。整个研究阶段,湖滨地区总体渔业产业结构调整的幅度和速率均处于加快阶段,且高于同期江西省。不同县市产业结构变动幅度与速率差异明显,2000年前,新建县产业结构变动情况据各县市之首,产业结构变动幅度达到6.2,e值达到4.1°,2001年后,该地位被鄱阳县取代。各县市产业结构变动幅度与产业结构变动速率的差异性从侧面反应了各区域渔业政策的和自然条件的独特性。为维持鄱阳湖渔业资源的可持续性,农渔部门应进一步加快产业结构调整步伐,扩大湖泊养鱼和农渔两用田规模,并减少人工饵料和有机肥料的使用,为鱼类生长创造健康的水生环境,实现鄱阳湖地区经济利益和生态效益的双赢。In this study, the structure characteristics of fishery production were analyzed in lakeside region of Poyang Lake from 1996 to 2008 by sector Kuzenets K value and Moore structure value. The results showed that fish gross production was increased steadily by 6%, of which culture was main section, and catching production was nearly steady with a little decrease. There was obviously difference in fish production between different counties in lakeside region under the natural conditions. The fish production in Nanchang county was leading among all the counties, accounting for over 1/6 of the gross fish production in lakeside region due to exceptionally natural resources. In the whole period, the adjustment of fishery resource structure speeded up in speed and rate, higher than Jiangxi provinces at the same period. There was significant difference in speed and rate between different counties in lakeside region. Before 2000, Xinjian County had the maximal K value （6. 2） and e value （4. 1~）. After 2001, however, the maximal K value and e value were observed in Poyang County, indicating that difference in the studied counties reflected the special trait on fishery policy and natural condition. To keep the sustainability of fishery resources in Poyang Lake, fisheries and agricultural department should speed up to adjust the sector structure additionally, to improve the area of fish farming and rice-fishing and to decrease the use of artificial diet and organic fertilizer in the lake. We can create health water condition for fish to make economic profit and ecological benefit in Poyang Lake.
