摘要:
 采用野外调查、平面量模拟立体量和三维绿量转换生态效益等方法，对宝鸡市城镇（郊）陡坡及人工立面景观林树种三维绿量及生态效益进行计算和评价。结果表明，宝鸡市城镇（郊）陡坡及人工立面主要包括11个景观林树种。单株三维绿量的计算结果表明，乔木中侧柏的单株平均三维绿量最大，为3.348 6 m3·株-1，单株生态效益较高；紫叶李最小，为0.467 2 m3·株-1，单株生态效益较低；灌木及藤本植物中山桃的单株三维绿量最大，为6.486 m3·株-1；迎春最小，为0.823 2 m3·株-1。通过对不同陡坡及人工立面景观林树种生态效益的比较，建议在宝鸡市城镇（郊）陡坡及人工立面绿化过程中更多采用常绿树种与落叶树种相结合，灌木与乔木相结合的方式。根据对7种景观林树种所建立的三维绿量回归模型方程，随着冠幅、树高、冠高等形态特征量的升高，单株三维绿量呈现上升趋势。在相似条件下可利用这些回归模型方程估算相应树种三维绿量值，为研究区域造林绿化数据库奠定基础，为宝鸡市环境友好型城市林业建设提供理论指导。
Abstract:
 Steep slopes and artificial facades in the sururban area are the difficult sites for landscape construction.Ecological benefits of landscaping tree species growing on the steep slope and artificial elevation in the urban and suburb areas of Baoji Municipality were calculated and evaluated based on the field survey,simulation of vertical quantity by plane quantity and estimation the ecological benefits by converting the LVV value.The average LVV per plant of 11 langscaping tree species growing in the study area was calculated.The results showed that among the arbor tree species,the largest average LVV belonged to Platycladus orientalis,which was 3.348 6 m3/plant with higher ecological benefits.While Prunus cerasifera had the least average LVV,which was 0.467 2 m3/plant.Among the shurb and rattan species,the average LVV of Amygdalus davidiana was the largest (6.486 m3/plant),whereas the average LVV of Jasminum nudiflorum was the least (0.823 2 m3/plant).Based on the comparison of the ecological benefits of the landscaping tree species,it was proposed that the plantation should be composed of evergreen tree species combined with deciduous tree species as well the shrub species should be combined with arbor tree species in the steep slope and artificial facade area.Based on the LVV regression model equations established for 7 landscaping tree species,the LVV per plant increased with the increase of morphological characteristics of crown diameter,plant height and crown height.The regression model equations might be adopted to calculate the LVV value of the landscaping tree species under similar site conditions,which could lay the foundation for the afforestation database building in the study area,and provide guidance for the construction of environment-friendly urban forestry in Baoji municipality facade area.
