中文摘要：

贵州省及其毗连地带地质结构复杂，生态系统多样。元明清时期，该区域土司进献给朝廷的贡赋大都为千姿百态的土特产品，这样的土产由于能与其生态环境、基层管理体制相互兼容，因此当地生态环境良好。其后随着西南边疆局势变化，朝廷在此推行了大规模的“改土归流”，导致贡赋类型、开发模式、基层管理体制的紊乱，无意中诱发了生态环境变迁。

英文摘要：

Guizhou Province and its adjacent areas have complicated geological structures and diverse ecological systems. In the Yuan, Ming and Qing Dynasties, Chieftains in these areas offered all kinds of native products as tributes dedicated to the imperial courts. The local products were compatible with the ecological environment and the grass-root management system, which resulted in a good ecological environment in those areas. With the changed situation in the Southwest borderland, the imperial court implemented bureaucratization of native officers on a large scale, leading to a disorder in tribute types, development mode and management system and bringing about changes of ecological environment undesignedly.
