草坪以其防风固沙、保水保土、美化环境、除尘减噪等功能,成为人类生存环境重要组成部分,受到人们越来越多的重视。据报道,进入20世纪80年代后我国草坪建植面积及对草种、草皮的需求,以每年大于20％的速度稳定增长。80年代每年进口草坪草种子量为50t左右,1994年增至300多t,1997年突破2000t,1999年已达4000t。我国西北地区深处内陆,气候干燥,冬季寒冷,生态环境恶劣,居民对草坪深为喜爱,可以预料在西部大开发中草坪业必将大发展。按照韩烈保等先生提出的中国草坪草气候生态区划,可将我国草坪草划分为9个气候生态带,西北5省区(陕、甘、宁、青、新)及内蒙古自治区西部属寒冷干旱带,该区年均气温8～11℃,年均降水量100～510mml,1月平均气温-26～-6℃,平均相对湿度35％～65％;7
Lawn with its wind and sand, water and soil conservation, landscaping, dust removal and noise reduction and other functions, as an important part of human living environment, by more and more attention. It is reported that after the 1980s China’s turfgrass planting area and the demand for grass species and turf grew steadily at a rate of more than 20% per annum. In the 1980s, the amount of turfgrass seeds imported per year was about 50 tons, increased to more than 300 tons in 1994, exceeded 2000 tons in 1997 and reached 4000 tons in 1999. Inland deep in the northwest of our country, the climate is dry, the winter is cold, the ecological environment is abominable, and the residents are deeply loved by the lawn. It is expected that the lawn industry will surely develop greatly in the western development. According to the lawn grassland ecological division proposed by Han Liebao and other gentlemen, the turfgrass in our country can be divided into nine climatic zonation zones, five provinces and autonomous regions in Northwest China (Shaanxi, Gansu, Ningxia, Qinghai and Xinhua) and the cold arid zone in the west of Inner Mongolia Autonomous Region, The average annual temperature is 8 ~ 11 ℃, the average annual precipitation is 100 ~ 510mml, the average temperature in January is -26 ~ -6 ℃ and the average relative humidity is 35% ~ 65% .7
