摘要
[目的]对恩施州分布的171种抗污染树种的绿化价值进行综合评价,为恩施州绿化树种的选用和配置提供理论依据。[方法]运用层次分析法建立以抗病性、耐高温高湿、耐瘠薄、吸收有害气体、滞尘、吸噪、观花、观叶、观果、观树形、无飞絮、无落花落果、无异香恶臭13项指标为综合评价指标,对恩施州171种抗污染树种的绿化价值进行综合评价。[结果]综合评价为I级的树种共31种,其中有针叶乔木1种,阔叶乔木25种,灌木5种;综合评价为II级的树种有69种,其中有针叶乔木5种,阔叶乔木46种,灌木12种,藤本6种;综合评价为III级的树种共44种,其中有针叶乔木2种,阔叶乔木23种,灌木19种;综合评价为IV级的树种共27种,其中有针叶乔木1种,阔叶乔木13种,灌木12种,藤本1种。[结论]I级树种可作为城市绿地首选树种,II级树种可作为城市绿地一般树种,III级树种应根据实际情况慎重选用,IV级树种不宜选用或可采用一定栽培措施适当选用。
[ Objective ] The greening value of 171 sorts of anti-pollntion tree which are widely distributed in Enshi City were comprehensively e- valuated, in order to provide theoretical basis for the selection and allocation of green tree species in Enshi. [ Method] By using AHP method, the evaluation index system was established by using 13 indicators including disease resistance, high temperature and humidity resistance, barren resistance, harmful gas absorption ability, dust-retention ability, noise absorbing ability, flower ornamental quality, leaf ornamental quality, fruit ornamental quality, tree ornamental quality, no catkins, no blossom and fruit droping, no exotic fragance and stench, the greening value of 171 sorts of antl-pollutlon tree in Enshi City were evaluated. [ Result] The results showed that altogether 31 tree species are at the I grade level, in- cluding 1 species of coniferous trees, 25 species of broad leaved trees, 5 species of shrubs ; the II grade level trees species are 69, induding 5 species of coniferous trees, 46 species of broad leaved trees, 12 species of shrubs, 6 species of vines ; the number of the Ⅲ grade level tree spe- cies are 44, induding 2 species of coniferous trees, 23 species of broad leaved trees, 19 species of shrubs ; and the number of the IV grade level tree species are 27,including 1 species of coniferous trees, 13 species of broad leaved trees, 12 species of shrubs, 1 species of vines. [ Conclu- sion ] I grade level tree species should be the first choices for greening work in city, and II grade level trees species should be widely used, Ⅲ grade level trees species should be used prudently according to the environmental characteristics, and IV grade level trees are not suitable for greening work, if they are used, proper measures should be taken to maintain these trees.
