Objective:To investigate the distribution of Lysimachiae Herba in five counties and districts（Xuy-ong County

Hejiang County

Jiang’an County

Gong County

Xuzhou District） in southern Sichuan

China

and toprovide a scientific and reasonable basis for the development and utilization of Lysimachiae Herba. Methods:Underthe guidance of the Technical specifications of the fourth national general survey of traditional Chinese medicine re-sources

quadrat survey

as well as mathematical and statistical methods

was used to analyze the reserves of Lysi-machiae Herba in southern Sichuan. Results:A total of 190 sample plots

950 sets of square

and 5700 quadratswere surveyed in the five counties and districts. The reserve of Lysimachiae Herba in Xuyong County was 140.6 tons

distributed at 105°17′ 27″ E to 105°39′ 01″ E

27°46′ 42″ N to 28°28′ 23″ N

and an altitude of 617 ～ 1250 m; the reserve of Lysimachiae Herba in Hejiang County was 181.98 tons

distributed at 105°52′ 09″ E to 106°14′07″ E

28°38′ 11″ N to 28°43′ 08″ N

and an altitude of 489 ～ 766 m; the reserve of Lysimachiae Herba in Jiang’an County was 84.85 tons

distributed at 104°58′ 28″ E to 105°11′ 35″ E

28°26′ 42″ N to 28°40′ 07″ N

and an alti-tude of 267 ～ 606 m; the reserve of Lysimachiae Herba in Gong County was 172.58 tons

distributed at 104°42′10″ E to 104°56′ 56″ E

27°57′ 03″ N to 28°14′ 55″ N

and an altitude of 406 ～ 877 m;the reserve of LysimachiaeHerba in Xuzhou District was 125.75 tons

distributed at 104°42′ 10″ E to 104°56′ 56″ E

27°57′ 03″ N to 28°14′55″ N

and an altitude of 406 ～ 877 m. Lysimachiae Herba was found in 61 quadrats and 98 quadrat sets. Conclusion:In the five counties and districts of southern Sichuan

there are large reserves of Lysimachiae Herba

whichcan be used as the raw material for related formulations. The results of general survey provide a scientific basis forthe protection and rational development and utilization of the herbal resource

and provide guidance for the develop-ment of related industries.
