In this paper, the author reviewed the history of physical anthropology in China and divided it into four stages: 1) introduction and acception stage (from the turn of 19th and 20th centuries to 1920’s), 2) localization stage (from 1930’s to 1949), 3) circuitous stage (from 1949 to 1976) and in-depth stage (from 1976 to now) and described the important incidents in different stages.
Using the input-output data of wheat production and climate data in five provinces of northwest Chinaduring 1978-2007, this paper studies the impact of global warming on the wheat yields in northwestChina. It concludes that the annual average temperature rises one percent, the wheat yields will reduce by 0.023%, while there is no significant impact of annual precipitation amount and annual sun-shining hours on wheat yields. In order to counter the impact of global warming on wheat production in northwestChina, it is necessary to explore the adaptive measures in farming practice, seed cultivation, use of arable land, and the prevention and mitigation of agricultural disaster.
