Doctoral Dissertation Research in Geography and Regional Science

这项博士论文奖将支持对亚利桑那州季风的晚第四纪气候和植物地理历史的研究。该项目的目的是提供关于在冰期-间冰期过渡期间假定的季风极大期的时间和范围的信息。该项目将阐明在重大人类影响之前发生的长期波动，从而增加我们对人类活动对气候影响的认识。它将通过建立全新世期间美国西南部的良好气候记录，为评估后农业和工业时期的气候变化提供所需的基线数据。该项目将加强我们对该国这一地区潜在沙漠化以及全球气候变化影响的了解。

This doctoral dissertation award will support a study of the late Quaternary climatic and phytogeographic history of the Arizona monsoon. The purpose of the project is to provide information on the timing and extent of the putative monsoonal maximum during the glacial- interglacial transition. The project will add to our knowledge of the effects of human activities on climate by illuminating the long-term fluctuations that occurred prior to major human impacts. It will contribute baseline data needed to evaluate the variability of climate in the post- agricultural and industrial periods by establishing a good record of climate over the U.S. Southwest during the Holocene. The project will enhance our understanding of potential desertification in this region of the country as well as of effects of global climatic change.
