【摘要】 托木尔大峡谷自然分布有野生植物131种,其中有不少种类具有潜在的园林观赏价值,可以作为温带荒漠区荒山绿化或城市园林绿地乡土植物加以开发应用。现选取综合景观功能、抗逆性和资源可利用潜力3个一级评价指标和12个二级评价指标,建立野生观赏植物资源综合评价模型,利用层次分析法,对131种野生植物进行综合评价。结果表明:可以作为乡土观赏植物进行开发利用的荒漠野生植物(综合评价指数>2.80)有68种,占总被评价种数的51.9%。将这68种野生观赏植物按综合评价指数的高低进一步划分为3个等级,其中:Ⅰ级(>3.50),共有5科5属6种;Ⅱ级(3.50~3.20),共有17科28属31种;Ⅲ级(3.20~2.80),共有17科29属31种。更多还原

【Abstract】 Grand Canyon has the distribution of 131desert plants,there are many species with high ornamental value.They can be used as temperate desert region the greening of barren hills or the native plants green garden city to develop application.The comprehensive landscape function,resource utilization potential on the basis of three first grade indicators and twelve level two indexes,and established the comprehensive evaluation model of wild ornamental plant resources were selected,by hierarchy process on 131kinds of wild plants were comprehensive evaluated.The results showed that as native ornamental plant for the development and utilization of wild plants in the desert(comprehensive evaluation index greater than 2.80)were 68kinds,the total was evaluated in 51.9%.The 68kinds of wild ornamental plants according to the comprehensive evaluation index was further divided into three grades,Among them:Ⅰlevel(>3.50),a total of5families and 5genera and 6species;Ⅱlevel(3.50~3.20),a total of 17families and 28genera and 31species;Ⅲlevel(3.20~2.80),a total of 17families and 29genera and 31species.更多还原
