摘　　要：采用气候土地生产潜力估算模型,通过对贵州清镇喀斯特溶原坝地与花江喀斯特峰丛峡谷的对比研究,得出决定喀斯特地区耕地生产潜力的首要自然因素为土壤条件,其次是热量条件,再次是水分条件,最后是光照条件。This paper takes a ratio investigation on cultivated land between Huajiang karst fengcong gorge and Qingzhen karst farmland in Guizhou, adopting the estimating model of climate - soil production potentiality. The results show that the natural elements which decide the production capacity of the cultivated land in karst area are soil conditions, temperature conditions, moisture content conditions, and sunshine conditions according to their significance.
