    摘要:

    為了定量討論番茄生長模型(DSSAT-CROPGRO-Tomato)中各參數(shù)對模擬輸出結(jié)果的影響,,運(yùn)用擴(kuò)展傅里葉幅度檢驗(yàn)(EFAST)法,,對影響番茄物候期,、生長及生產(chǎn)等3類模型輸出的各參數(shù)敏感性進(jìn)行了研究,,重點(diǎn)探討了模型輸入中品種參數(shù),、氣象及土壤參數(shù)變化對模型輸出結(jié)果的影響,。結(jié)果表明:影響番茄開花期,、坐果期和成熟期等物候期最敏感的品種參數(shù)和氣象參數(shù)分別為初花期積溫、日最低溫度,,而土壤參數(shù)對番茄物候期的影響可以忽略,。影響番茄葉面積指數(shù)和冠層高度最敏感的品種參數(shù)為初花期積溫,而影響番茄根,、莖生長最敏感的品種參數(shù)為干物質(zhì)分配比例,,日最高溫度和土壤田間持水率分別是影響番茄根、莖,、葉生長最敏感的氣象和土壤參數(shù),。影響番茄干物質(zhì)量和總產(chǎn)量最敏感的品種參數(shù)為初花期積溫,,而影響番茄收獲數(shù)量和單果質(zhì)量的品種參數(shù)為最大單籽粒質(zhì)量,日最高溫度和土壤田間持水率也分別是影響番茄生產(chǎn)最敏感的氣象和土壤參數(shù),。

    Abstract:

    Sensitivity analysis plays an essential role in the processes of crop model localization. It is important to quantify the sensitivity of input parameters of model for crop model calibration and application. In order to quantify the effects of input parameters variation on the sensitivity of CROPGRO-Tomato output variables, the extended Fourier amplitude sensitivity test method was applied to perform global sensitivity analysis. The most sensitive parameters for anthesis, fruit set and maturity date were the photothermal days in the early flowering period (EMFL) among the cultivar parameters, and the average minimum air temperature among climate parameters, while the phenology of tomato was not affected by soil parameters in the model. Among the cultivar parameters, the most sensitive parameters for leaf area index and canopy height was EMFL, while the most sensitive parameters for growth of root and stem was the maximum fraction of daily growth. The growth of root, stem and leaf was affected sensitively by the average maximum air temperature (TMXD) and the soil field capacity (SDUL) among climate and soil parameters, respectively. The most sensitivity parameters for the tops weight at maturity and fresh fruit weight was EMFL, while the most sensitivity parameter for number of fruits at maturity and single fruit weight was maximum weight per seed among cultivar parameters. TMXD and SDUL were also the most sensitivity parameters for tomato production among climate and soil parameters. The research result indicated that EFAST method was a feasible way for CROPGRO-Tomato model calibration and application.
