明清时期关中—天水地区人口高速增长,特别是清前期呈现爆炸性增长态势,由此,土地垦殖加速,农田水利得以开发,进而推动了农业的较大发展,为解决人口的生存问题起到了基础性作用。然而,由于人口暴增,生产力水平不高,环境意识不强,农业开发的盲目性也逐步加剧,使植被遭到严重破坏,导致环境恶化,水土流失、灾害频发、河流浑浊、河道变迁等环境问题随之而来。明清时期是关中—天水地区环境变迁较为剧烈的时期。

Therefore, land reclamation was accelerated and farmland water conservancy was exploited, which in turn promoted the great development of agriculture and laid the foundation for solving the problem of population subsistence Sexual function. However, due to the population explosion, the low level of productivity and the weak environmental awareness, the blindness of agricultural development is also gradually aggravated, causing serious damage to vegetation and causing environmental degradation, soil erosion, frequent disasters, river muddiness and changes in river courses. Environmental problems ensued. Ming and Qing Dynasties is Guanzhong - Tianshui area environment changes more intense period.
