北京市不同草种节水潜力预测

Predicted Water-saving Forecast of Different Grass Species

从论述北京市水资源总量及构成入手,发现北京市生活用水总量呈逐年递增的态势。引用其他专家的实验成果数据,根据北京市5种常见草种的最大最小蒸散量计算得出各草种的节水潜力,进而根据时间序列模型预测未来几年北京市草坪面积变化趋势,计算几种草种的节水潜力大小。得出暖季型草种节水潜力以及未来节水空间均较大的结论。

This paper discusses the total water resources and constitute a start in Beiiing,found that the total water in Beijing was increasing year by year trend,which is caused by increased urban green space to increase public environmental water are not unrelated. This experimental results of other experts cited the data,according to five common grass species in Beijing evapotranspiration calculated maximum and minimum water saving potential in the grass, then according to the time series model to predict the future trend of recent years, Beijing lawn area, calculated the size of water-saving potential of several grass species. Draw warm--season grasses and future water saving potential of space are large conclusions.
