摘要

应用植被恢复评价指标对兰州市北山地区不同植被恢复模式的总体质量进行了评价，结果表明，S值法是干旱区植被恢复模式筛选的有效方法。有补水条件造林区，水平台+鱼鳞穴+生态垫覆盖+人工灌木群落(柠条、侧柏、甘蒙柽柳、沙冬青)模式是植被退化区效果明显的恢复模式。无灌溉造林区，V形水平沟+鱼鳞坑+地膜覆盖+天然植物群落+红砂模式是阳坡(半阳坡、梁峁)地段最佳模式；鱼鳞坑+地膜覆盖+天然植物群落+红砂+柠条是阴坡(半阴坡)地段最佳模式；鱼鳞坑+天然植物群落+甘蒙柽柳是沟谷地段最佳模式。任何条件下，人工封育+天然植物群落都是效果明显的植被恢复模式。

Abstract

This paper assessed the quality of different vegetation rehabilitation models in the north mountain region of Lanzhou City by related evaluation index.The results show that the method of S value is an effective method for selecting vegetation rehabilitation in arid area.The model of contour plat form+fish-scale-like pits+ecological pad cover+ artificial bush communities(K or shinsk peashrub

Platy cladusorientails

Tamarix austromongolica Nakai

Ammopiptant husmongolicus)is the most effective vegetation rehabilitation method in the irrigation area.For no irrigation afforestation area

the model of V type contour plat form+fish-scale-like pits+plastic covering+natural plant communities+Reaumuria is the most effective path in south slope(semisunny slope

ridge area)

and the model of fish-scale-like pits+plastic covering+natural plant communities+Reaumuria+K or shinsk is the best model in shady slope(semishady slope).The model of fish-scale-like pits+natural plant communities+Tamarix austromongolica Nakai is a good way in gully area.Hill closure+ natural plant communities is an effective revegetation method for all cases.
