地径是园林绿化苗木测量中，表示测量位置的一个术语。地径是指树(苗)木距地面一定距离处直径，与树径、胸径相类似，通常用于表示树木、苗木的规格。 共同的认识是指“苗干靠近地表面处的直径”，而实际应用中则是地面以上20公分。

The differences in height and ground diameter of seedling and clonal seedlings among provenances were of significant level by variance analysis. The latitude, longitude and altitude of 41 provenances had significant effect on height growth of seedlings.2.
苗期试验表明,不同种源间实生苗、无性苗苗高、地径筹异较大,经方差分析,结果均达到极显著水平,短技木麻黄种源实生苗、无性苗高生长的地理变异趋势较为一致,即苗木高生长与原产地经纬度、海拔三个因素的关系不太紧密,种源产地对苗木生长无显著影响。
