| 摘 要： | 本文研究了电白县4种人工林的遮光度,叶面积指数和光合作用强度以及光合生产量,比较了各种人工林的生物生产量和光能利用效率。认为有多层多种结构的混交林具有良好的生态效益和经济效益,是今后营造人工林的方向。窿缘桉纯林虽然有很高的光合作用强度,但由于纯桉林缺少中下层植物,因此光能利用率和生产量都很低。白藤在不足全光照10％,益智在不足5％的光照下,仍然生长很好,它们都有很高的光能利用效率,分别是3.92％和4.11％,而且这两种植物都有一定经济价值,因此是营造多层多种混交林较理想的中下层植物。

| Abstract: | In the paper we study on the absorption of light, values of leaf area or leafarea index, photosynthetic rates and photosynthetic productivity for four artificial forests in Dian Bai County, Guang Dong. The biological productions and the utilization ratio of sun light energy are compared. The results show that the multistorey artificial communities have fine ecological effects and economical benefits. Therefore the construction of multistorey and multispecific a-rtificial communities is needful. By reason of... |
