城市绿地是城市生态环境的重要组成因子之一。发展城市绿地，不仅可为城市居民创造良好的环境，而且通过改善城市人居环境，可促进旅游业和服务业的发展，创造更好的外商投资环境，促进城市经济的发展。以绵阳市为研究对象，采用回归分析方法，分析了绵阳市城市绿地规模与经济发展水平间的定量关系，结果表明二者相关显著。此外，还建立了绵阳市城市经济增长与各驱动因子间的多元线性回归模型，并据模型对绵阳市2005-2010年城市经济增长对人均公共绿地面积的需求做了初步预测。

Development of urban green land will not only create more favorable and comfortable living environment for urban citizens,but also promote indirectly and notably the development of urban econ-omy through improvement of living environment of urban citizens, tourism and service businesses and therefore investment environment for businessmen from other regions of the country or abroad, The quantitative relationship between the area of urban green land and the economic development levels of the urban area of Mianyang City was analyzed with the approach of correlation analysis. The result indicated that ther was a significant correlation between them. In addition, a linear multivariate correlation model between GDP values and. its three relevant driving factors of Mianyang City was developed. With this model, a preliminary prediction of the future demands to public green land area in the city,Where was related to the future growing of urban economy during the period from 2005 to 2010,was quite closed to the value provided by the green land planning of the city at the same year,which indicated that both the ap- proach and the results of this study had a rather good reliability.
