摘要:
 金莲花是一种重要的非木质野生药用植物资源，其资源产量及产量与环境因子的关系研究，对于合理利用、保护金莲花资源具有重要意义。以桃山林场金莲花为研究对象，通过GPS与GIS技术获得资源分布图与面积，采用对一级单位分层的二阶抽样方法调查单位面积产量与总产量；并通过逐步回归确定影响金莲花产量的光照与土壤因子。结果表明：不同生境类型的金莲花面积与平均单位面积产量差异较大，其中，沼泽草甸面积最大（48.185 hm2），荒坡面积最小（1.952 hm2）；荒坡平均单位面积产量最大（7.502 kg·hm-2），林下最小（1.518 kg·hm-2）；总体单位面积产量为5.530 kg·hm-2，研究区域的金莲花总产量为434.543 kg。影响金莲花产量的环境因子主要为直射率、土壤含水量与容重，且土壤浅层（0~10 cm）比深层（10~20 cm）影响显著。
