[Using of method and result of LUCC study in field of Chinese medicine resources]

The contradiction between the ecological environment, natural resources and the development of social and economic has become increasingly conspicuous. Land resources are the physical basis of Chinese medicine resources and habitat of the medicinal organisms. Meanwhile, land resources are also the bridge and tie between Chinese medicine resources and environment that include society and natural environment.
