Abstract Based on the inter-constraint and inter-adjustment system balance between environment and earthwork，the environment earthwork problems in permafrost region of Qinghai-Tibet plateau is discussed with a view of macro and micro environment. Firstly，the atmosphere environment development，ground temperature zone，the suitable principle and condition of earthwork design decided by landscape ecology are discussed on macro environment aspect. Secondly，the environment changes by the constructive force of nature and the probable environment destruction and engineering hazard caused by earthwork construction are discussed on micro environment aspect. Thirdly，on the condition that the macro environment can not be controlled or can only be directed to a less worse situation by more comprehensive efforts，the principle and method are discussed for protecting environment in earthwork construction.

Key words： soil mechanics permafrost environment earthwork system balance
