摘　　要：需冷量对落叶果树适地适栽、设施栽培和预测气候变化具有重要的意义。需冷量估算模型的研究为落叶果树需冷量的深入研究和理解提供了理论基础:0～7.2℃模型和犹他模型是应用较广的模型,动力学模型是目前较为完善的模型,0～14℃低温模型,正犹他模型和改进的犹他模型是针对当地特殊气候而采用的一些模型。对落叶果树需冷量及其估算模型的研究进行了综述,主要从落叶果树需冷量的概念、不同需冷量估算模型的介绍,应用及模型间的选择、需冷量影响因素以及我国需冷量研究存在问题与展望等方面进行阐述,以期为我国落叶果树需冷量的研究提供借鉴。Identification of chilling requirement is of great significance in selecting the appropriate species for a given region, protected cultivation and predicting impact of climate change on the deciduous fruit crops. The study of chilling models provided a theoretical basis for further investigation and better under- standing of chilling requirements of deciduous fruit crops： 0 to 7.2℃ model and Utah model are widely used at present;Dynamic model is considered to be a better model; 0 to 14℃ model, positive Utah model and modified Utah model are suited for special areas or climates. In this paper, we reviewed the concep- tion of chilling requirement of deciduous fruit crops and chilling models, the selection of different chilling models, influencing factors of chilling requirement and the problems and prospects of chilling requirement research in China..
