1 引言 长期以来,大平原地区以恶劣和多变的气候而著称。持续的干旱以及尘暴是这一区域自然条件变化的结果。除了这些由来已久的问题之外,气候变化的阴影也一直笼罩着人们。大气中与日俱增的二氧化碳导致全球和区域气候的变化,这种预言是全球气候模型(GCM)在具体地区应用的结果。全球气候模型是主要的研究气候变化对农业生产影响的手段。长期的研究表
1 Introduction The Great Plains region has long been known for its harsh and ever-changing climate. Continued droughts and dust storms are the result of changes in the natural conditions of the region. In addition to these longstanding problems, the shadow of climate change has also been shrouded in people. Increasing atmospheric carbon dioxide leads to global and regional climate changes that are the result of the Global Climate Model (GCM) application in specific regions. The Global Climate Model is a major tool for studying the impact of climate change on agricultural production. Long-term research table
