Taking fishery development and ecological protection of Poyang Lake as research object,this paper elaborated the relation between fishery development and ecological protection from physiological characteristics and functions of fish species by the method of field survey and consulting related data. Finally,it came up with recommendations of increasing plagiognathops microlepis and Xenocypris davidi Bleeker and adopting and deepening healthy ecological and water body stratification. Besides,government organizations,local supervision authorities,scientific research institutions,and enterprise operating entities should jointly maintain and promote breakthrough mechanism for ecological balance of Poyang Lake water system.展开更多

The results show that there is a great difference in fragility of the economic system between different administrative units; the difference in resilience is the major factor responsible for difference in fragility of the economic system in various cities and counties within the region; according to the difference in fragility characteristics,we conduct classification as follows: Nanchang City is a low-sensitivity and high-resilience type; Jiujiang City is a high-sensitivity and high-resilience type; Jiujiang County,Xingzi County,Yongxiu County,Hukou County,Duchang County,Ruichang County,De'an Xian,Wuning County,Pengze County,Leping City, Dongxiang County,Fengcheng City and Gao'an City are a high-sensitivity and low-resilience type; other cities and counties are a low-sensitivity and low-resilience type.展开更多

The results show that compared with the national average, the environmental loading ratio is relatively low in this area; the net emergy yield rate is high; the sustainable development ability is strong. Finally according to the results of emergy analysis, corresponding countermeasures are put forward as follows: develop agriculture based on the existing rich natural resources; increase technological inputs; develop circular agriculture; promote sustainable agricultural development.展开更多
