Popis: The traditional hydrology method, stable hydrogen and oxygen isotope technology, and rainfall simulation method were combined to investigate the hydrological function of small experimental plots (2 m×1.2 m) of contrasting architecture in Northwest Guangxi dolomite area. There were four typical catenary soils along the dolomite peak-cluster slope, which were the whole-sand, up-loam and down-sand, the whole loam, up-clay and down-sand soil types, respectively. All the experimental plots generated little amounts of overland runoff and had a high surface infiltration rate, ranging from 41 to 48 mm·h综合运用传统水文学、氢氧稳定同位素和原位模拟降雨等方法,研究了桂西北白云岩坡地典型土体构型石灰土微区(2 m×1.2 m)土壤水文功能.白云岩峰丛坡地沿坡向下表现出通体砂、上壤下砂、通体壤、上黏下砂4种典型石灰土土链格局,所有构型土体微区地表稳定入渗速率高达41~48 mm·h
