摘要

[Objective]The research aimed to study the response of plant climatic productivity to warming and drying tendency in Huanren in the past 58 years.[Method]Based on the temperature and precipitation data in Huanren from 1953 to 2010,using trend analysis,Thornthwaite Memorial model and Mann-Kendall detection method,change characteristics of climate and plant climatic productivity in Huanren were analyzed,and the regression evaluation model between plant climatic productivity and temperature and precipitation was established.[Result]Annual average temperature in Huanren presented a significant upward trend,and its linear tendency rate was 0.29℃/10 a;annual precipitation presented a decreasing trend,and its linear tendency rate was-13.29 mm/10 a;dryness presented a declining trend.The warming and drying trend was obvious in Huanren.Plant climatic productivity presented a significant increasing trend,and its linear tendency rate was 8.39 g/(m2·10 a).Plant climatic productivity was closely related to precipitation and temperature.[Conclusion]The research could provide basis and reference for the adjustment of agricultural structure and sufficiently playing the advantages of climate resources in Huanren.
