Since the Ming Dynasty, that area has been transformed from marginalization to backland. The infiltration of the central power and the massive influx of immigrants began to impact on the traditional agricultural foundation. The ecological agriculture and the domestic animal farming was replaced step by step by ecological agriculture only, with large areas of land reclaimed and forest grassland resources used. This has put great pressure on the ecological environment in the northwest of Guizhou.

自明代以来，黔西北地区开始由边缘化向内地化转变，中央权力的渗透和外来移民的大量涌入，开始日益冲击着黔西北传统农业的根基，使黔西北农业兼畜牧型生态模式逐渐转化为农业为主体的生态模式，大批的荒地被开垦，森林植被和草场资源得到最大极限的利用，这给黔西北的生态环境造成了极大的压力。

To exam the validity of the Bloch-Grüneisen formula at megabar pressures, we use the electrical conductivity data point of ε-iron at relatively low pressure (～40GPa) reported by Keeler as a reference point, a formula for calculating the conductivity of the ε-iron under high-pressure and temperature was deduced via Bloch-Grüneisen,where v is specific volume , T is temperature and σ is electrical conductivity .
