【摘要】：为了解贵州不同季节番茄气候生产潜力的变化趋势、空间差异以及番茄气候资源利用规律,研究基于贵州省81个气象站1961~2015年的气象资料,采用逐步订正、GIS空间插值和线性趋势分析等方法,分析番茄的光合、光温和气候生产潜力的时空变化特征。结果表明:冬春番茄的光合和气候生产潜力均呈递减的变化趋势,递减率分别为174.11、226.52 kg/(hm~2·10 a),而光温生产潜力为递增的变化趋势;夏秋番茄的光合、光温和气候生产潜力均为递减趋势,递减速率分别为355.24、317.99、427.67 kg/(hm~2·10 a);空间分布特征表明,冬春番茄的气候生产潜力空间上自东南向西部递减的趋势,夏秋番茄的气候生产潜力呈西南向东北递减的趋势;分别对番茄光合生产力分别进行温度、水分订正,冬春、夏秋番茄的平均气候减产率分别为35%、15%,其中降雨量是番茄气候生产潜力的主要限制因子。
[Abstract]:In order to understand the change trend, spatial difference and utilization regularity of tomato climatic resources in different seasons in Guizhou, the meteorological data of 81 meteorological stations in Guizhou Province from 1961 to 2015 were studied. The spatial interpolation and linear trend analysis of GIS were used to analyze the spatial and temporal variation characteristics of photosynthesis, light and climate potential of tomato. The results showed that the photosynthetic potential and climatic potential of winter and spring tomato were decreasing, the decline rate was 174.11226.52 kg/ (hm~2 10 a), and the photosynthetic potential of summer and autumn tomato was increasing. The climatic potential of light and climate is decreasing, and the decreasing rate is 355.24317.99427.67 kg/ (hm~2 10 a);), which indicates that the climatic potential of winter and spring tomato is decreasing from southeast to west in space. The climatic potential of tomato in summer and autumn decreased from southwest to northeast, and the photosynthetic productivity of tomato was revised by temperature, water, winter and spring, respectively. The average climatic yield of tomato in summer and autumn was 350.The rainfall was the main limiting factor of tomato climatic production potential.
