试论自然环境对明清苗族经济模式的制约

A Trial Analysis on Influence of Natural Environment on the Miaos’Economy during the Ming and Qing Dynasties

苗族在适应西南山区特定的自然环境的过程中，形成了独具特色的以山地农业为特征的经济模式。自然条件不仅制约苗族产业结构的发展，促成了各经济部门的特点，而且成为对外交流的障碍，对苗族经济发展产生重大而深远的影响，苗族社会经济长期滞后，很大程度上与自然环境以及由此决定的生产条件的状况有着直接的关系。

In the process of adapting specified natural environment in southwestern moun-tain areas, the Miaos has evolved an economic mould characterized by mountainous agriculture. Natural Conditions not only restrict the Miaos’ development in productive structure but also hin-der the external exchange. Its influence on the Miaos’ economy is great and profound. The long - standing backwardness of the Miaos’ economy, to a great extent, has a direct bearing on nat-ural environment and its decided productive conditons as well.
