摘要
使用简化的中国生态林业工程综合效益评价指标体系 ,对川渝 77县长防林 (一期 )工程的效益进行了综合评价。主要结论是 :迄今川渝防护林综合效益为 1985年时 (启动前 )的 7倍 ,到 2 0 10年将达到 9.6 6倍 ;以柏木、马尾松、云南松等 8种树为主要树种 ,尚需优化调整 ;从流域看 ,对效益的贡献以次为金沙江、嘉陵江、峡江、渠江、涪江。
Using simplif synethetical benefit evaluation index of ecological forest engineering of china,We evalutate synethetically the benefit of 77 county's first peroid engineering shelter forest In sichuan and chongqing. A conclusion is drawn that up to now the synethetical benefit is 7 times and by year 2010 it is 9.66 times as much as that of year1985(starting time).Eight tree type,such as cupressus funebris?pines massoniana?pines yunnanensis etc must be adjusted.On basin view, The main contribution to the benefit is Jinsha river?Jialin river?Xia river?Qu rever?Fu river?Tuo river in order.
