尽管西南岩溶地区石漠化趋势严重,但真正做到生态、经济、社会三效益统一的岩溶石漠化生;态重建模式的实践工作却做得很少,且对于这些实践活动还缺乏理论的总结和思考.花江峡谷顶坛片区,充分利用当地的适生植物资源和干热资源优势在石漠化土地上种植花椒、砂仁等喜热耐旱的经济作物,在恢复和治理生态的前提下成功调整了农业内部结构,形成以花椒规模种植为核心的特色产业,利用雨水、坡面水、岩溶裂隙水,实行参与式社区管理,使环境、经济与社区文化得以可持续发展."顶坛"模式是充分利用岩溶环境资源优势,寓山地保护于特色农业开发之中的一个成功例子,它启示我们,岩溶石漠化土地恢复重建必须重新认识岩溶环境优势,因地制宜,对过去侧重于水土保持的传统治理模式进行创新. |

There are few ecological rehabilitation practices models of karst rocky desertification which really integrate ecological, economic and social benefits though the rocky desertification trend is serious in karst mountain areas of southwest China, and there is a lack of theoretical sum-mary and thinking. People take advantage of the native plant resources and dry and hot climate superiorities to grow economic vegetation such as Zhathoxylum planispinum var. dingtanensis and Viuvous Amomum, et al, which adapt to dry and hot environments at Dingtan of Huajiang karst gorge, adjust agriculture inner structure successfully with the eco-environment restoration, develop distinctive agriculture characterized by pla-nting Zhathoxylum planispinum var. dingtanensis on a large scale, and make use of rain water and surface water and epikarst water, practise participatory community-based resources management. All these enable the eco-environment, economiy and community of Dingtan to have a sustainable development. Therefore, the successful experience of " Dingtan model should be a reference to the karst rocky desertification com-prehensive control practice in southwest karst region in China. |
