By learning a lesson from the painful experience in the postWenchuan Earthquake reconstruction planning of disasterstriken towns, such problems should be taken into consideration: effectively solving the problem of vast population and limited land in mountainous towns, settling the contradiction between shortterm emergency reconstruction and longterm planning, and coordinating the conflict between public interests and personal benefits. The reconstruction planning of disasterstriken towns is a gigantic systematic project, involving work on regional economy, natural ecology, humanity history and engineering technology, etc.. To provide reference for the postdisaster reconstruction planning, the authors make a preliminary study on the basic method and strategy of the reconstruction planning from such aspects as optimization of the spatial layout of towns, the coordinated development of nature and town, protection of history and culture and creation of town characteristics, and disaster prevention and reduction planning,etc..
