古夜郎国植根于喀斯特环境。
The ancient Yelang Country is produced in the karst environment.
研究结果表明：喀斯特环境高度异质性，小生境小气候环境差异较大。
Then gave a series of technical measures. The result shows that: Karst environment's high heterogeneity, microhabitat and micro-climate are very different.
喀斯特环境有成土过程缓慢、土层浅薄、土被不连续、土壤持水量低、植被覆盖率低的特点。
The karst region is very fragile eco-environment with slow soil formation process, shallow and discontinuous soil, small water holding capacity, and low vegetation coverage.
