| 摘 要： | It is difficult to afforest in rock desertification region and is the key area for eco-environment treatment. To speed up the comprehensive treatment of rock desertification, several anti-rock desertification modes implemented in Dingtan region, located on the right bank of Huajiang Grand Valley in Beipanjiang Town, are introduced as examples. This paper first analyzes the natural and environmental conditions, the development of rock desertification in the Din gtan region, then the detail of the treatment modes, such as ＂Chinese wingleaf pricklyash -pig breeding - marsh gas＂ （Mode One）, ＂ amomum villosum - pig breeding - marsh gas＂ mode （Mode Two）, ＂traditional grain and economic crop （corn, peanut） - amomum villosum or Chinese wingleaf pricklyash＂ （Mode Three）, etc. The eco-economic effects, potential and shortcomings of the above mentioned modes are analyzed and compared. It is proved that Mode One and Mode Two are of good economic effect, but Mode Three of better ecological effect. Solutions to the shortcomings of the modes are also put forward.

It is proved that Mode One and Mode Two are of good economic effect, but Mode Three of better ecological effect. Solutions to the shortcomings of the modes are also put forward. |
