摘　　要：在豫西丘陵区刺槐无性系生长量增长率与林龄和年积温呈反比,与年日照时数和冬春季降雨量呈正比,在气象因子中,积温对刺槐无性系生长率影响最大,高温是影响该地区刺槐无性系生长的主要因子,冬春季降雨量也对刺槐无性系的生长产生重要影响。The annual growth rate was inversely proportional to the stand age and annual cumulative temperature,and was negative proportional to sunshine hours and rainfall during winter and spring.The annual cumulative temperature was the main climate factor which posses a largest effect on the growth of black locust,and the rainfall during winter and spring also had a very important impact on the growth.
