广西都安三只羊乡的生态重建对策

广西都安三只羊乡多石,少土,缺水,人均耕地面积少,原生植被少,农作物经济效益低,能源不足,农民文化素质较低,自然灾害(旱、涝)发生频繁,生态环境恶劣,石山荒漠化,森林覆盖率低,水土流失严重.但是,该乡具有生态重建的客观条件,以及技术和资金保障,可以对该乡进行封山育林、营造人工林、发展良种水果种植、发展科学的养殖、实施集水及节水灌溉工程、综合利用沼气能源、举办各种技术培训提高农民素质等,来恢复和重建该乡及周边地区的生态环境,实现该乡"种植-养殖-沼气-种植"的良性生态循环.

Research on Present Ecological Conditions and Reconstruction in Guangxi Duan Sanzhiyang Area

Guangxi Duan Sanzhiyang area is a typical limestone region that is poverty-stricken in southwest China.In this area there are so many stones,so less soil,and extremel lack of water on the surface of the earth.The natural ecological conditions are very bad for human living.And after many years' disorderly exploitation and destruction,the natural environment and its system has become extremely weak and deteriorated rapidly.In this paper,we research into the natural conditions and the present ecological state of Sanzhiyang area,such as climate,water and soil resource,biological community and vegetation,etc.According to its natural conditions and climate,we reconstruct its ecological system by planting forests and increasing the green surface area;at the same time,we provide the scientific methods and technology for planting and breeding,helping the local people to shake off poverty and develop the local economy.This research will provide a scientific method for reconstructing the ecological system of the whole karst mountain area in southwest China.
