摘要: 基于贵州省81个气象站1961—2015年的气象资料,采用逐步订正和线性趋势等方法,分析水稻的光合、光温、气候生产潜力的变化特征和气候资源利用率。研究结果表明:贵州省水稻光合、光温和气候生产潜力均随时间推进而呈现递减趋势,递减速率分别为484.46、206.78、357.38 kg·hm-2·10 a-1。空间分布上,光合生产潜力总体表现为东西部高、中北部低,光温生气潜力表现出由东南部向西北部递减的变化趋势,气候生产潜力与光温生产潜力空间分布基本一致。水稻气候资源利用率多年平均为9.06%,随时间变化呈递增趋势,递增速率为0.017%·a-1

Abstract: Based on the meteorological data of 81 meteorological stations in Guizhou Province during 1961-2015, the photosynthetic potential productivity, photo-thermal potential productivity, climatic potential productivity and climatic resources utilization of rice were evaluated with successive correction analysis. It was shown that the photosynthetic potential productivity, photo-thermal potential productivity, climatic potential productivity of rice in Guizhou Province exhibited decrease trend, with decrease rates of 484.46, 206.78, 357.38 kg·hm-2·10 a-1, respectively. The spatial distribution of the photosynthetic potential productivity was high in eastern and western region, while low in the central and northern region. While, the spatial distribution of photo-thermal potential productivity and climatic potential productivity showed a decrease trend from southeast to northwest. The temporal variation of rice climate resource utilization showed an increase trend at the rate of 0.017%·a-1, and the average annual climate utilization rate was 9.06%.

Key words: rice, climatic potential productivity, climatic resources utilization, change trend, Guizhou Province
