摘　　要：笔者通过样方法对山西省陵川县野生连翘群落的生态因子进行调查,并对其生长指标进行测定。结果表明,陵川县野生连翘在海拔1 100 m~1 400 m的中山生长及结果情况较好,在半阴坡、半阳坡结果量较高,在淋溶性褐土和山地褐土构成的山体间分布面积较大。陵川县野生连翘集中分布区的年平均气温为6.9℃~7.2℃,区域内森林覆盖率高于60%,年降雨量在650 mm~800 mm之间,山体间年平均湿度在60%~75%之间。根据野生连翘生长区域内灌木和草本的重要值,可将其分为6类优势组群。野生连翘青果产量和其生境密不可分,为增加青翘产量,需采取合理的经营措施。The ecological factors of the wild Forsythia suspensa community in Lingchuan County of Shanxi Province was investigated through sampling methods and its growth indicators was measured.Results showed that wild Forsythia suspensa in Lingchuan County grew and bore fruit well in the middle mountain area which altitude was 1100 m~1400 m.The yield was higher on semi-shaded and semi-sunny slopes.The distribution area between mountains composed of leached brown soil and mountainous brown soil was larger.The annual average temperature in the concentrated distribution area of wild Forsythia suspensa in Lingchuan County was 6.9℃~7.2℃.The forest coverage rate in the area was above 60%and the annual rainfall was between 650 mm~800 mm.The annual average humidity between mountains was between 60%~75%.According to the importance values of shrubs and herbs in the wild Forsythia suspensa area,it could be divided into 6 dominant groups.The yield of wild Forsythia suspensa was closely related to their habitat environment.To increase the yield of Forsythia suspensa,reasonable management measures needed to be taken.
