Abstract
The zoning' boundaries of permafrost are theoretically determined fromthe relation between permafrost and modern climate in this paper. The boundary elevations are given in a profile. There are many phenomena demonstrating a commondegeneration, such as buried frozen soil, pseudo-permafrost land forms, variations ofpatchy permafrost table, multigelation, and vegetation changing in different regions.The important conclusion is that a basic trend of the permafrost changing in theplateau is degeneration.
