温室效应将导致下世纪中叶前后全球气候明显变暖。为了适应气候变暖对我国农业生产的重大影响，必须增加农业投入以采取相应的对策措施。本文提出一种新的研究模式─—生产水平函数，并运用此函数初步计算及讨论了气候变暖情景下山东、河南及全国的农业种植业投入费用的问题。 The greenhouse effect will lead to a marked warming of the global climate around the middle of the next century. In order to adapt to the significant impact of climate warming on agricultural production in China, we must increase agricultural input to take appropriate countermeasures. In this paper, we propose a new research mode - production level function, and use this function to initially calculate and discuss the investment cost of agricultural planting in Shandong, Henan and the whole country under the climate warming scenario.
