Abstract: Biological conservation corridor (BCC) is an applied type of landscape ecological corridors. The basic concept, theoretical foundation, structure and role, quality and function, efficiency validation, construction, and management of BCC were introduced. There were more theoretical discussions than practices o n BCC, and the importance of community participation in BCC planning and design became common understanding but had lesser case study. A detailed analysis of Xish uangbanna BCC revealed the key roles of community participation in the BCC plann ing/design and practice. The co-management pattern of community participation w ould be the important way in BCC research and practice in the future.

Key words: Inverse Lagrangian dispersion analysis, Forest evapotranspiration, Eddy covariance method
