The results show that the migrants＇ domestic income has increased in the last 10 years, which originated from the tncreasing trend of active and extensive rural labor migration, while the resettlement has not influenced the domestic income significantly. The resettlement stimulates younger farmers to work.far away from home whose wages contribute nearly 80% of domestic income, The resettlement decreases their savings due to higher expenditure of daily life for those who work far away from home, and higher expenditure of food for those who stay at home, losing cultivated lands with irrigation system for vegetable. On the other hand. the increase of rural labor migration leads the migrants who stay at home to have access to more cultivated lands for rice and cotton, and the farmers also apply more fertilizer in the same cultivated land for more agriculture products. The resettlement makes most of migrants spend their savings on the improvement of their housing conditions due to not enough governmental financial support for new building. After the analysis, some factors that influence migrants＇ income and consumption are discussed. The paper may contritbute to the building of Poyang Lake Ecological Economic Zone.展开更多
于2014年9月24至26日在鄱阳湖通江水道湖口至屏峰段使用SIMRAD EY60回声探测仪对鱼类资源进行水声学调查.结果显示,鄱阳湖通江水道鱼类目标强度平均值为-56.4±6.4 d B,范围为-69.9^-32.1 d B;估算的平均全长为7.6 cm,范围为1.2~98....于2014年9月24至26日在鄱阳湖通江水道湖口至屏峰段使用SIMRAD EY60回声探测仪对鱼类资源进行水声学调查.结果显示,鄱阳湖通江水道鱼类目标强度平均值为-56.4±6.4 d B,范围为-69.9^-32.1 d B;估算的平均全长为7.6 cm,范围为1.2~98.0 cm;鱼类资源的平均密度为53.7 ind./1000 m3,范围为0~441.7 ind./1000 m3.在水平分布上,鱼类主要分布在湖口县、鞋山和屏峰附近3个水域.区域Ⅰ和区域Ⅲ的鱼类密度显著高于区域Ⅱ的鱼类密度;区域Ⅲ的鱼类个体大小显著小于区域Ⅰ和区域Ⅱ.在垂直分布上,多数鱼类栖息于主河槽的深水区,且大个体更倾向于深水区.在此基础上,利用Arc GIS地统计插值方法估算鄱阳湖通江水道湖口至屏峰山水域鱼类总数量约为6.2×107ind.,总生物量约620 t.结果表明,鄱阳湖通江水道是鱼类重要的栖息地,建议加强该水域的保护,保持鄱阳湖与长江的自然连通.展开更多
