耶鲁大学研究人员今天发表的一项新研究表明,美国主要城市的绿色城市面积在过去五年中扩大了12%,其中中等大都市地区增长幅度最大。 A new study released today by Yale University researchers reveals that urban green spaces in major U.S. cities have expanded by 12% over the past five years, with the most significant growth in mid-sized metropolitan areas. 根据卫星图像和城市规划数据得出的研究结果表明,地方供资增加和社区主导的举措正在推动这一趋势。 The findings, based on satellite imagery and city planning data, suggest that increased local funding and community-led initiatives are driving the trend. 研究人员指出,这种扩张与空气质量的提高和居民满意度的提高相关,但告诫说,公平获得服务在有些社区仍是一项挑战。 Researchers note that the expansion correlates with improved air quality and higher resident satisfaction but caution that equitable access remains a challenge in some neighborhoods.
