通过对祁连山西水林区灌丛草坡型、灌丛灌木林型、低价值乔林型、河滩弃耕迹地型等4种主要植被类型进行3年的封育试验和研究，结果表明：（1）河滩弃耕迹地型群落盖度增加值最大，为31％；低价值乔林型增加值最小，为15％；4种类型盖度平均增加值为22％。（2）灌丛灌木林型的平均地径增加较大，为1．23 cm ；低价值乔林型的灌木层平均地径增加最小，为0．12cm，但乔木层的平均胸径增长幅度最大，为3．0cm。（3）灌丛灌木林型的平均高度增加较大，为1．51m ；河滩弃耕迹地型群落的平均高度增加最小，为0．34m ；低价值乔林型的乔木层平均高度增长幅度最大，为3．52 m。

Four main vegetation types (shrub-grass type ,thicket-shrub type ,low-valued arbor type & abandoned o-verflow land) in Xishui Forest Zone were conducted enclosure experiments for three years .Result shows that :(1) the added value of community coverage for abandoned overflow land are the most ,being 31% ;added value of low-valued arbor-type is the least ,being 15% ;the average added value of the four types of coverage are 22% ;(2) the average ground diameter of thicket-shrub type is larger being 1 .23 cm ;the mean ground diameter of low-valued ar-bor type is the least ,being 0 .12 cm ;but the tree layer ,the average grow th rate of DBH is the maximum ,being 3 .0 cm .(3) the average height of thicket-shrub type increases larger ,being 1 .51 m ;the average height of community for abandoned overflow land increases the minimum ,being 0 .34 m ;the average height of the tree layer of low-valued arbor type increases the largest ,being 3 .52 m .
