Abstract: Microclimatic measurements and flux determinations were made on natural Agropyron-Koeleria grassland during two growing seasons. The calculated evaporation fluxes were analyzed in terms of the potential evaporation, soil moisture content, and plant water potential. The analysis fitted Monteith's canopyresistance concept. The fraction of net radiation in volved in evaporatin was closely correlated with green leaf area index during the first half of the growing season, and with soil water content (0-30 cm) during the latter half of the growing season. Seasonal water-use estimates, by micrometeorological and soil moisture balance approaches, agressd to within 10%. |
