典型喀斯特峡谷石漠化地区生态农业模式探析——以贵州省花江大峡谷顶坛片区为例

A study on the models of eco-agricultural development in typical Karst Gorge Region-A case study from Dingtan District of Huajiang Gorge in Guizhou Province

简介了典型喀斯特石漠化发育的花江大峡谷顶坛片区自然环境条件及其石漠化现状,分析其正实施的治理石漠化的几种生态农业发展模式(花椒-养猪-沼气模式、砂仁-养猪-沼气模式、传统粮经作物(包谷、花生等)-砂仁、花椒套种模式)效应,并提出发展对策。

Taking Dingtan District of Huajiang Gorge as an example, the natural conditions, the development current of rocky desertification, and the models of eco-agricultural development for controlling the rocky desertification such as ＇Chi- nese prickly ash ＋ breed pigs ＋ marsh gas＇ model, Alpina zerumbet （pets） Burtt ＋ breed pigs ＋ marsh gas＇ model, ＇ grain crops and economic plants ＋ Chinese prickly ash or Alpina zerumbet （pers） Burtt＇model and its development countermea- sures are put forward.
