利用Penman-Monteith和联合国粮食及农业组织Blaney Cridle方程得出了冷季型草坪草的消耗利用系数。这些蒸散量（ET）方程对不同气候条件区域的可传递性大于原始基于温度的Blaney-Cridle方程，之前已为其制定了草坪系数。这些系数为执业工程师提供了信息，允许使用国家气象局的自动地面观测系统等来源的完整气候参数数据，将ETr转换为冷季草坪的ETcrop。ETcrop值代表城市供水系统所需的水量。 包括16个参考文献、表格和图表。

Consumptive-use coefficients for cool-season turfgrass have been developed using the Penman-Monteith and United Nations Food and Agriculture Organization Blaney-Criddle equations. Transferability of these evapotranspiration (ET) equations to regions of varying climatic conditions is greater than that of the original temperature-based Blaney-Criddle equation, for which turfgrass coefficients were previously developed. The coefficients provide practicing engineers with information that permits the conversion of ETr to ETcrop for cool-season turfgrass using data for the complete range of climatic parameters available from sources such as the Automated Surface Observing System of the National Weather Service. The ETcrop values represent the water required of city water systems. Includes 16 references, tables, figure.
