【摘要】 以温室番茄(Lycopersicon esculentum mill)生产为例,介绍了作物生长模型TOMSIM在光合生产潜力空间分析中的应用。在结合试验数据对TOMSIM进行参数调试和验证的基础上,利用我国各大城市1981~2000年的历史时期室外辐射资料,以日为时间步长,进行多年温室番茄光合生产潜力的模拟。结合地理信息系统工具,做出了温室番茄产量的空间分布图,同时图示了温室番茄的高产区、中产区和低产区。将模拟产量与统计产量进行对比分析,指出了我国的温室番茄生产的发展潜力所在。
【Abstract】 The model TOMSIM was introduced to spatial estimation of photosynthesis production potential,and greenhouse tomato production in China was analyzed by this method.After TOMSIM was validated by former experimental data,using external radiant data from 1981 to 2000,photosynthesis production potential was simulated. The simulating step was one day.By GIS tools,spatial distribution map of greenhouse tomato yield was draw.With yield isoline,high and low productivity zones can be seen on the map.When actual yield was compared to the simulating yield,enormous potential of greenhouse tomato production can be find.
