构建一个经济-气候新模型评价气候变化对粮食产量的影响

Assessing the Effect of Climate Changes on Grains yields with a New Economy-Climate model

将气候变化研究和农业经济研究相结合,构建了一个经济-气候新模型,用来评价全球气候变化对粮食产量影响的问题。提出在经济模型C-D生产函数中添加气候变化因子,建立一个新的评价模型,作为连接气候变化因素和经济变化因素的桥梁,并对该模型的性能及合理性进行了初步的模拟和验证。

Effect of global climate changes on grain yields is assessed using an economy-climate model, which integrates economy and climate change. The new （C-D-C） model for assessing and predicting the effect of climate changes on grain yields is developed by introducing climate change factors into the C-D （Cobb-Dauglas） production function, and the preliminary simulation and verification of the model are performed.
