On May 12, 2008, Great Sichuan Earthquake was occurred, and 87,000 people were died or had not been found. The City of Dujiangyan, World Heritage City had heavily destroyed. We proposed the reconstruction plan and conceived the importance of “Linpan” which is the traditional village style in this region. We carried out extensive research, applying three methods. The first is the analysis of the distribution, using satellite imagery with 2.7 m ground resolution. The second is the research of its structure and function and the third is social and economic system underlying land use. The following four points were clarified. Linpan seems to be regarded as a type of agro-forestry which contains sustainable land use system. The characteristics of distribution pattern is scattered and the distance between each Linpan is approximately 300m. The type of vegetation is classified into 5 types. Tall trees form the skyline of Linpan, and under the forest, various agricultural activities are deliberately maintained. Finally, the key factor of Linpan is the irrigation system which was established 2300 years ago. From above findings, we conclude Linpan is not a simple agricultural village, but important cultural heritage in Sichuan which should be preserved and activated in process of reconstruction.
