摘要
以生态系统服务价值定量评价的现有成果为手段 ,针对北京市的具体问题 ,对北京市人工草地与人工林木、人工景观水面与人工湿地的生态服务价值进行了估算和对比分析 .结果显示北京地区的人工草地和人工景观水面的生态服务价值皆为负值 ,而人工林木和人工湿地的生态服务价值较高 ,所以种草不如种树 。
According to quantitatively evaluating and comparing the ecosystem services of artificial grassland and cultivated trees, artificial pool and constructed wetland in Beijing by the well accepted method, it was found that the net ecological values of grassland and pool are all negative. It was suggested that cultivated trees are more beneficial than artificial grassland and constructed wetland than artificial pool.
