例如，岩质土，不能挖掘坑洞式厕所；

3·They were luckier than their fellow Puritans atPlymouth Bay, who subsisted as independent farmers, wresting meagre harvests ofmaize from the rocky soil of New England.

4·This enables them to grow in areas that receive good sunlight but have rocky, untillable soil.

7·The most essential process of karst rocky desertification is soil loss.
土壤流失是石漠化最基本的过程之一。
8·Factor of soil circumstance was an index of rocky desertification type and indicated the spatial difference of lithology.
土壤环境因子表征了石漠化在空间上岩性的差异特征，是石漠化类型的表现指标。
9·Rocky desertification in the karst region is related to stratum and lithology, incising of river, soil erosion, gradient and human activities, etc.

10·Compared with Karst no-Rocky Desertification soil, the content of soil Organic Matter and Nitrogen in various degrees of Karst Rocky Desertification shows a tendency to drop suddenly.
且土壤有机质、全氮、酸水解性总氮、氨基酸态氮和碱解氮含量按照石漠化程度的由轻度到极强度而呈递减趋势，但土壤其他氮素含量并未表现相同的变异规律。
