Abstract：Rocky desertification region was the difficult area of afforestation and the key area of eco-environment conservation. In order to accelerate comprehensive control, Dingtanpian region on right bank of Huajiang Gorge where Karst rocky desertification develops typically was taken as an example. Based on expatiating natural conditions and actual rock desertification conditions of Dingdianpian region, several eco-environment conservation models of anti-rocky desertification which were being brought into effect were analyzed in detail, such as "Bambooleaf pricklyash+breed pigs+marsh gas"(model one) "Amomum villosum+breed pigs+marsh gas model"(model two)"Traditional grain and economic crop (corn, peanut)+Amomum villosum or Bambooleaf pricklyash model"(model three), etc. The eco-economic benefits, development potential and problems of these models were studied. The results showed that in the terms of economic benefits, model one and model two were better, model three was the best. And aiming at existing problems, countermeasures for next works of anti-rocky desertification were put forward briefly.
