据调查,山西省的梯田埂坎类型,依筑埂材料划分主要有土质埂坎和石质埂坎两大类。土质埂坎依据不同部位土体的密实程度又可分为硬埂、软埂和复式埂。石质埂坎按砌筑方式可分为干砌石坎和浆砌石坎,从埂坎结构型式上又可分为单墙式和双墙式。埂坎占地比率是测算埂坎资源量的重要指标,据典型调查加权平均计算,全省梯田复式埂占地率15.22%,土质硬坎占地率7.35%,石质埂坎占地率7.65%,埂坎平均占地率8.21%。根据1996年底全省梯田面积统计核实资料和不同埂型平均占地率测算成果,求得全省梯田埂坎资源面积共计7.294万hm2,其中,土质硬坎3.548万hm2,复式埂2.851万hm2,石坎0.895万hm2。
According to the survey, the type of terrace ridge in Shanxi Province is divided into two categories: soil ridge and stone ridge according to the material of the ridge. Soil 埂 ridge according to different parts of the soil compactness can be divided into hard 埂, soft 埂 and double 埂. Stone ridge ridge according to the masonry method can be divided into dry stone ridge and stone masonry ridge, from the ridge structure type can be divided into single-wall and double wall. According to the weighted average of the typical survey, the occupancy rate of terrace terraces in the province is 15.22%, that of soil hard beds is 7.35%, and that of stony ridge Occupancy rate of 7.65%, hut average occupancy rate of 8.21%. According to the statistical data of the terraced fields in the whole of 1996 and the calculation results of the average occupying rate of different types of terraces, the area of the ridge terraces in the province totaled 72,994 hm2. Among them, the soil hardness was 35,480 hm2, 28,510 hm2, stone ridge 0.895 million hm2.
