园林绿化对美化城市、减轻噪声、固沙吸尘、调节小气候、保护生态环境等,有极大的作用。而以人工进行种植、改造和管理的草坪又是城市园林绿化的重要组成部分。根据1983年不完全统计,国内30个省会及风景城市平均绿化覆盖率为18.3％(见表1)。全国城市人均公共绿地面积高于5.1平方米的大、中、小城市分别已育5、3、8个(见表2)。公共绿地中,草坪种植面积占着极大的比重。近几年来草坪面积又有了很大的发展,仅以首都为例,1966年曾确定当年要铺草54万m~2,五年规划确定栽草皮和低被植物155万m~2,
Landscaping plays an important role in beautifying the city, alleviating noise, fixing dust, regulating the microclimate and protecting the ecological environment. The artificial planting, transformation and management of the lawn is an important part of urban landscaping. According to incomplete statistics in 1983, the average greening coverage of the 30 domestic capitals and scenic cities in China was 18.3% (Table 1). Large, medium and small cities with per capita public green spaces in urban areas of over 5.1 square meters have 5,3,8 children (Table 2). Public green space, lawn acreage accounts for a large proportion. In recent years, there has been a great development of lawn area. Only in the capital, for example, it was confirmed in 1966 that 540,000 m 2 should be planted in the year and 1,500 m 2 planted with turf and low-
