摘 要:青海省是长江、黄河、澜沧江的发源地 ,全省森林覆盖率仅为 0 4 3% ,是我国森林覆盖率最低的省份 ,生态环境堪忧 :森林资源遭到破坏 ;草场严重退化 ;盲目开荒 ;土地沙化 ;水土流失 ;水资源短缺 ;生物多样性面临威胁 ;自然灾害频繁。因此改善生态环境已是当务之急。据此提出了建立生态林业体系 ,实现可持续发展的若干对策。Qinghai province was the headstream of Yangzi River, Yellow River and Lancangjiang River. The very low forest coverage of 0 43% of Qinghai, was the lowest among all the provinces of China. It was threatened by a series of ecological problems such as decreasing forest resources, degradation of pasture land, unreasonable reclamation, desertification, soil and water loss, short of water resources, diminished biodiversity and frequent natural hazards. To tackle those problems, improving ecological environment was the task of the top priority. Some strategies were therefore worked out focusing on establishing ecological forestry system and realizing sustainable development.
