西安地处关中盆地,属于典型的温带大陆性季风气候,年平均气温在13.5℃左右,年降水量在505.7～985.3毫米之间。市区中的植被比较丰富,绿化覆盖率达到了39.7%,人均公共绿地面积达到了5.5平方米。在秦岭山脉的作用下,其热岛效应比较明显。因此,城市绿化对于西安生态功能的构建具有积极意义。草坪在西安的整个植物群落中占有重要的地位和很大的比重。多年来,它净化了城区大气,调节了城区小气候,发挥了降低噪声、光污染等综合生态功能,抑制了水土流失,为保持城区土壤整体质量作出
Located in the Guanzhong Basin, Xi’an is a typical temperate continental monsoon climate with annual average temperature of 13.5 ℃ and annual precipitation of 505.7-853.3 mm. Urban vegetation is rich, green coverage rate reached 39.7%, per capita public green area reached 5.5 square meters. The role of the Qinling Mountains, the heat island effect is obvious. Therefore, urban greening has positive significance for the construction of ecological function in Xi’an. Lawn in Xi’an, the entire plant community occupies an important position and a large proportion. Over the years, it has purified the urban atmosphere, tempered urban microclimate, played a comprehensive ecological function such as reducing noise and light pollution, restrained soil and water loss, and made an effort to maintain the overall quality of urban soil
