英文摘要：

Primary eco-tourism resources of karst mainly include the natural and human primary ones, which are characterized by their frangibility, rarity and irregeneration. As valuable historic-natural heritages and important resources, they play a significant role on developing local tourism industry and economy. The advantages and characteristics of tourism resources in the karst mountain areas of Guangxi owe to their primitive ecology. But because of the fragile eco-environment and the concentrative habitation of the minorities, the exploitation of the tourism resources is with particularity. In the paper, the types and formation of primitive eco-tourism resources in karst mountain areas of Guangxi are summarized, and the mechanism of frangibility is analyzed. Complicated landforms and laggard transportation lead to the relative blockage of the areas with little external disturbance, so the tourism resources are primitive. But low speed of soil formation in limestone areas, obvious soil erosion, and hard environment for vegetation growth, all make karst mountain areas of frangibility with strong eco-sensitivity, low carrying capacity, vulnerability, and irregeneration features. Some ideas are put forward for safe protection of the primary ecotourism resources, i.e. establishing multi-grade declaration system of the local heritage resources, setting up ethical eco-museum, or ethical cultural eco-park, and constructing a gene pool of ethical cultures, etc.
