Besides conventional light- ning protection technology, local lightning protection, pre-discharge and lightning motoring and early warning techniques should be used to protect coastal wind farms against lightning.展开更多

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
