异地互动:自然灾害驱动下的移民——以1761-1781年天山北路东部与河西地区为例

Interaction between Different Regions： Immigrants by the Impacting of Natural Disasters Taking the Eastern Section of the North Slope of Tianshan Mountains and Hexi Region during 17 61 ~ 17 81 for Example

根据乾隆二十六年至四十六年（1761～1781）天山北路东部和河西地区的移民政策与自然灾害的相关信息，对两地由于移民而形成的互动关系进行研究，试图从一个小尺度的范围内，为认识在自然灾害下异地互动提供一个实证。1761～1781年，河西地区发生了两次严重的干旱事件，在国家政策的支持下，也出现了两次向天山北路东部移民的高潮。而巧合的是，同时期天山北路东段却是自然灾害的低发期。从两地自然灾害发生的规律看，灾害发生正好处于错位，也就是说两地之间自然灾害发生时间的不同步性，为政策性移民提供了良好的自然条件，也使从河西地区移民到天山北路东部出现高潮成为可能。

The research about interaction based on the immigration policy and natural disasters be- tween Tianshan northeast section and Hexi area during 1761-1781 ,and try to provided a example, for understanding interaction in different areas, in the same time, there have been twice severe droughts in Hexi area and appeared twice immigration climax to northeast tianshan road in support of national pol- icy. the same period,Tianshan northeast section is a low incidence of natural disasters, and so to pro- vide a good natural conditions for policy immigration.
