摘要
湖南省芷江县退耕还林工程从2003年实施以来,造林面积达8.15万hm2,取得了显著的生态效益。本文从固碳释氧、涵养水源、阻滞尘埃和保持生物多样性等方面阐述了芷江县退耕还林以来取得的生态效益,为建设"绿色侗乡"、打造"和平名城"作出了巨大贡献。
The conversion of cropland to forest began from 2003 in Zhijiang County,Hunan Province.The afforestation area has reached 81 500 hm2 and achieved great ecological benefits.This paper expounds the ecological benefits of conver-sion of cropland to forest in Zhijiang County from the carbon fixation and oxygen release,water conservation,blocking dust and maintaining biodiversity,which has contributed much to ‘green Dong’and ‘peaceful city’.
