摘要
本文对不同群落结构内的柞木进行了野外生理指标的活体测定,研究和分析了其日变规律,并从生理指标上为开拓效应带、提高林分净初级生产力提供了依据。同时,应用多元分析的方法对柞木的生理指标与小气候因子的关系做了探讨。结果表明:(1)具有效应带之群落内净光合总量明显高于对照区,同时,净光合一天中二次峰值之间时间延长2h;(2)生理指标与小气候因子的多对多线性模拟表明,蒸腾与相对湿度关系最密切,呈正相关,净光合与气温、绝对湿度关系较大,真光合、吸呼与土壤温度关系较大,均呈正相关。
Many studies and analyses were carried on daily dynamic regulation in this paper by living-measurment on physiological index of Oak tree in different community structures stands. It provides scientific basis for effect belt of increasing NPP of stand. Meanwhile, relationship between physiological index and microclimate factors was researched by polyanalysis method. it makes a remarking way for natural Oak forest in the future and a theoretical foundation for management.
