英文摘要	Plastic-film mulching in arid fields under drip irrigation has widely been replaced by biodegradable film mulching (BFM) to avoid plastic-film residue pollution. However, existing ET models are not able to accurately represent field evapotranspiration (ET) under BFM due to the disintegration of biodegradable film. Therefore, this study proposed an improved ET model considering BFM (BSW) based on the Shuttleworth-Wallace model (SW), and the performance of the model was compared with those of the SW, Penman-Monteith (PM) and modified Shuttleworth-Wallace models considering plastic-film mulching (MSW). In addition, the models were validated against observed data from a two-year (2018-2019) maize field experiment under high, medium and low drip irrigation with the depths of 30, 22.5, and 15 mm, respectively. The BSW model performed well with a normalized root mean square error (NRMSE), normalized mean absolute error (NMBE) and index of agreement (IA) for ET under different irrigation depths of 0.12, 0.25, and 0.96, respectively, and 0.10, 0.22, and 0.95 for evaporation (E) under different irrigation depths, respectively. During the early growing stage (elongation and tasseling stage), the BSW model obtained MBEs of cumulative ET (MBECET) and cumulative E (MBECE) of 2.1 and 5.6 mm, respectively, similar to those of the MSW model under high irrigation, but with MBECET estimation accuracy improved by 95.3% and 97.7% compared with the SW and PM models, respectively. The BSW model showed further improvements in estimation accuracy during the middle and late growth seasons (filling and maturation stages) with average MBECET and MBE CE of 1.5 and 0.8 mm, respectively for both years. In addition, the E/ET under BFM was decreased with increasing of irrigation depth, while E/ET was positively correlated with the disintegrated area of biodegradable film.
