【摘要】 本文对乌鲁木齐市四种不同绿地类型:公园绿地、防护绿地、附属绿地和其他绿地的园林植物进行适宜性评价。选取41科79属192种园林植物作为参评植物,采用专家打分法和层次分析法筛选参评因子及确定指标权重,利用指数和法建立评价模型。通过实地调查测量、资料数据检索、专家咨询调查获取指标数据值,并用量化标准将指标数据值量化,将园林植物适宜性综合指数进行分级。结果表明:根据专家打分法和层次分析法确定了18个评价指标及各指标在不同绿地类型中的权重。各种绿地类型在城市绿地中的功能和作用是影响指标权重的主要因素。利用评价模型计算出乌鲁木齐市城市绿化园林植物适宜性评价指数。其结果为:在公园绿地植物适宜度分级中,评价为Ⅰ级有9科11属13种,评价为Ⅱ级有27科50属88种,评价为Ⅲ级的有26科40属81种,评价为Ⅳ级的有8科9属10种;在防护绿地植物适宜度分级中,评价为Ⅰ级有19科39属71种,评价为Ⅱ级有24科42属68种,评价为Ⅲ级的有15科25属37种,评价为Ⅳ级的有10科13属16种;在附属绿地植物适宜度分级中,评价为Ⅰ级有18科25属37种,评价为Ⅱ级有31科51属106种,评价为Ⅲ级的有17科27属42种,评价为Ⅳ级的有6科6属7种;在其他绿地植物适宜度分级中,评价为Ⅰ级有19科24属36种,评价为Ⅱ级有25科42属96种,评价为Ⅲ级的有20科29属44种,评价为Ⅳ级的有10科14属16种。筛选了乌鲁木齐市192种园林植物的优势科、属,其中优势科为杨柳科(Salicaceae)、榆科(Ulmaceae)、蔷薇科(Rosaceae)和豆科(Leguminosae),优势属为杨属(Populus)、蔷薇属(Rosa L)和榆属(Ulmus L)。并对192种园林植物的科属进行地理成分分析。更多还原

【Abstract】 This paper aims at existing landscape plants in Urumqi city, and landscape plants are assessed through different type of green space which include Park Green Space, afforested lands, Attached green space and other type green space. Choosing 41 Families, 79 genera and 192 species as evaluation plants, using method of scoring by specialist and the Analytic Hierarchy Process (AHP) to confirm indexes and ensure the weight of them. According to indexes sum method establish assessment model and field survey, data search, expert consultation, public questionnaire, and then quantitative data index. Finally suitable comprehensive indexes about landscape plants are classified. The result showed that :We are determined 18 suitable assessment indexes and weight of landscape plants. In different types of green space shows different weight in different indexes, and the types of green space is closely related to function and effect of all kinds of green space in the Urumqi city.Suitable assessment indexes of landscape plants in Urumqi city can be counted by using evaluation model. The result showed that the class of suitable degree of plants in the Park Green Space is that 9 families 11genera 13 species in the rank ofⅠ, 27 families 50genera 88 species in the range ofⅡ, 26 families 40genera 81 species among theⅢand 8 families 9genera 10 species in the scope ofⅣ; The result showed that the class of suitable degree of plants in the afforested lands is that 19 families 39genera 71 species in the rank ofⅠ, 24 families 42genera 68 species in the range ofⅡ, 15 families 25genera 37 species among theⅢand 10 families 13genera 16 species in the scope ofⅣ;The result showed that the class of suitable degree of plants in the attached green space is that 18 families 25 genera 37 species in the rank ofⅠ, 31 families 51 genera 106 species in the range ofⅡ, 17 families 27genera 42 species among theⅢand 6 families 6 genera 7 species in the scope ofⅣ; The result showed that the class of suitable degree of plants in the other type green space is that 19 families 24 genera 36 species in the rank ofⅠ, 25 families 42 genera 96 species in the range ofⅡ, 20 families 29 genera 44 species among theⅢand 10 families 14 genera 16 species in the scope ofⅣ.The paper classified dominant families and genera of landscape plants in Urumqi city. The Dominant families are Salicaceae, Ulmaceae, Rosaceae, Leguminosae, and dominant genera are Populus, Rosa, Ulmus. And also analysis the geographical elements of its families and genera of 192 species landscape plants更多还原
