| 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 platform +fish-scale-like pits+ecological pad cover+artificial bush communities(Korshinsk peashrub,Platycladus orientails,Tamarix austromongolica Nakai,Ammopiptanthus mongolicus) is the most effective vegetation rehabili... |
