| Abstract: | Raoyang Experimental Area in Huang-Huai-Hai Plain,Which used to be a low production area,is under one of the national key scientific and technological projects,now it is changed into a area with good eco-environment,high production and high forest coverage by comprehensive management.The construction of the compound agricultural and forest ecosystem changed the local ecological condition,meteorological factors,content of CO2,dust content in air and bird numbers.Forest coverage was increased from 2% to 20%,crop yield was increased from 1.5t/ha to 7.5/ha.Remarkable ecological and economic benefits have been achieved. |
