Based on full field survey and data collection, the conservation planning for the rare and risk plant species in the three provinces is studied. The 65 plant species in the area protected by the state are divided into several groups according to artificial conservation status and plant distributions and aboundances, and several types of the conservation planning are put forward. On the on-ther-spot conservation side, the establishments of six nature reserves, two national parks and more than 40 protection spots are proposed. On the off-the-spot conservation side, it is suggested to set up a multiply off-the-spot conservation network that consists of a regional off-the-spot center, three provincial-level conservation and breeding bases and a lot of small plant transplantation gardens. Furthermore, an "on-the-spot and off-the spot" conservation planning is proposed, which combines the advantages of the two kinds of conservation. In addition, a "naturalizatoin" planning is particularly emphasized, which requires that the artificial breeded populations of the rare and risk plants should be naturalided to their original habitats.
