野生太子参的生态适宜分布区划

Ecology Suitability Regionalization of Wild Pseudostellaria heterophylla

为了野生太子参资源开发保护和合理利用提供依据,对野生太子参生态适宜分布区域和最优生境进行了区划研究。结果表明:野生太子参最适宜区面积达33.04万km2,主要分布在辽宁南部,山东中、南部,河南、湖北、安徽接壤处,安徽、江苏、浙江3省接壤处。同时筛选到年均降水量、最冷季平均温、最湿季平均温、最湿月降水量和土壤类型等5个因子对野生太子参的生长分布影响较大。

In order to provide the basis for wild resources protection and rational utilization of P. heterophylla, the ecological distribution and optimal habitat in the wild were studied. Results：The area of moderately and highly suitable habitats for wild P. heterophylla in the study area was 330 400 km2. The moderately and highly suitable habitats were mainly distributed in the southern Liaoning, middle and southern Shandong, Henan, the border of Henan, Hubei and Anhui, as well as Anhui, Jiangsu and Zhejiang. Meanwhile, the coldest average annual precipitation, average temperature, average temperature of wet season, the wettest month of precipitation and soil types are the most important ecological factors influencing the distribution of P. heterophylla.
