据1983—1985年试验研究结果表明,广东橡胶林能具有类似于热带次生林的小气候生态环境,能有效地控制水土流失;其土壤肥力能较快恢复以至有所提高,系统内物质循环能趋于动态平衡。实践证明,橡胶林人工生态系统有良好的生态效益、经济效益和社会效益。我国开发利用热带地区的经验是成功的,坚持合理的、高标准的开发和科学管理(如胶园的林网化、梯田化、覆盖化、良种化),植胶后能较快地出现新的生态平衡。在热带草原或荒山草坡植胶,会明显地改善当地的生态环境,即使以橡胶林更替低山丘陵区的热带次生杂木林,也不会引起当地生态环境变劣和经济收益下降。
According to the experimental results from 1983 to 1985, Guangdong rubber plantation can have microclimate ecological environment similar to that of tropical secondary forest, and can effectively control soil erosion; its soil fertility can be recovered quickly and even increased, and the material circulation in the system tends to dynamic equilibrium. Practice has proved that rubber plantation artificial ecosystem has good ecological, economic and social benefits. Our country’s experience in developing and utilizing the tropical regions is successful. Adhering to reasonable and high-standard development and scientific management (eg, afforestation, terraformization, covering and seed improvement in rubber plantations) The ecological balance. Planting gums on the savannah or barren hills and grass slopes will obviously improve the local ecological environment. Even if the rubber secondary forest replaces the tropical secondary mixed woods in hilly areas, it will not cause deterioration of the local ecological environment and decrease in economic returns.
