本文以清代黔东南地区农林产业在经济开发下的土地利用与覆被变化为论述对象 ,对影响农林用地变化的社会经济和生态结构因素作深入分析 ,认为该地区局地范围内历史上形成的农林并重经济发展模式和土地利用方式不仅利于生态环境的维护 ,而且极大促进了地区经济的不断发展 ,其在土地利用过程中形成的生态 -生产结构相对优化 ,有着进一步良性发展的潜力。但是由于影响农林生产发展的社会经济制度在深层次里存在着不合理性 ,使农林经济开发的良性运作缺乏必要保证 ,进而出现地方环境与社会恶性发展的危机。
Based on the analysis of the changes of land use and cover under the economic development of agriculture and forestry in Qiandongnan in Qing dynasty, this paper analyzes in depth the social, economic and ecological structural factors that affect the change of land for agriculture and forestry. Both agro-forestry and economic development mode and land use mode not only benefit the maintenance of ecological environment, but also greatly promote the continuous development of regional economy. The ecological-production structure formed in land use process is relatively optimized and has the potential for further benign development. However, due to the unreasonableness of the socio-economic system that affects the development of agriculture and forestry at a deep level, the benign operation of agricultural and forestry economic development lacks the necessary guarantee and further leads to the crisis of the local environment and the vicious social development.
