Abstract: Ecological and agrometeorological field experimental observation are of vital importance for the research of ecology and meteorology to obtain basic data.Construction of ecological and agrometeorological field stations,continuous monitoring air,water,soil,climate,and biological conditions,obtaining the results of the comprehensive impact of weather and climate factors on the ecosystem is important for us to improve scientific cognition of interdisciplinary science,such as agrometeorology,ecology,environmental science and other disciplines.This paper discusses construction background of the Ecological and Agrometeorological Field Experimental Base in Northeast China,main ecological and agrometeorological problems of this region,regional representative of site selection,researching target,function and orientation,observation items and equipment,shortage,planning and so on.The construction of Ecological and Agrometeorological Field Experimental Base in Northeast China can improve the monitoring and early warning capability and provide meteorological support for ecological protection.
