广西岩溶峰丛洼地生态果园的建设及其效应

A Preliminary research on the construction and effect of eco-orchard in the peak-cluster depression of Karst area in Guangxi Province

广西的岩溶峰丛洼地是岩溶地貌的典型代表,是自然条件最恶劣、生态环境最脆弱的区域。本文根据广西岩溶峰丛洼地特殊的自然环境特点,提出建设以桃树为主,采用金银花、旋扭山绿豆作为果园覆盖植物,种植、养殖、沼气三位一体的生态果园,并对其综合效益进行了初步探讨,认为该模式是兼顾经济效益、生态效益和社会效益的生态农业立体模式,是岩溶峰丛洼地生态重建和发展经济的有效途径。

The peak-cluster depression in Guangxi is the representative of Karst physiognomy, where the natural condition is abominable and eco-environment is fragile. According to the natural eco-environment of peak-cluster depression of Karst mountain area in Guangxi, this paper presents an eco-orchard development model of growing-raising-marsh gas, and analyses its effects. The model is considered to be a ecological agriculture model which considers the economic results, ecological and social benefit, and is the effective way to the eco-reconstruction and economic development in the peak-cluster depression of Karst mountain.
