福建山区耕地主要熟制的气候评估模型

Climatic assessment models for main cropping system of mountain areas in Fujian Province

福建山区耕地以水稻为主茬作物的熟制主要有双三熟制和单二熟制。该研究建立了这些熟制的3个气候评估模型,即①生长季适应性评估。建立了主要作物生育期钟模型模式,反映作物生长发育随气候的动态变化,并将生育期与气候生长季进行对比分析,实现生长季适应性评估;②产量表现评估。建立主要作物产量-气候经验模式,评估作物在各地的产量表现;③其它约束条件的评估。是对上述两条评估未考虑到的其它必要气候条件的评估。主要熟制气候评估模型的建立,为传统的定性评估向定量评估的转变提供了一条有效的途径。

Climatic assessment models for main cropping system of mountain areas in Fujian were developed. (1) Assessing seasonal growing adaptation to climate; 'clock' models for growing period of crops were established, which reflect dynamic change in growing period of crops with climate, and analyze the crop requirements to climate tondition; (2) Assessing crop yield: weather-yield models for some crops were developed to evaluate the crop yield conditions in various areas; (3) Assessing other required climate conditions. The establishment of the climatic assessment models for major cropping system provided an effective way to change from traditional qualitative assessment to quantitative.
