| 摘 要： | 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。

| Abstract: | On the basis of the relevant data collected during 1983-1985, a comprehensive analysis has been made of the microclimatic characteristics such as light, temperature, water, wind , etc., as well as run-off, soil erosion, soil fertility and rubber production in various rubber plantations in Hainan Island and West Guangdong. The results showed that a plantation with "windbreak-rubber trees- leguminous green manure" structure constitutes an artificial ecological system enjoying large amount of net radiation, as well as a humid and windless microclimatic environment favorable for the growth of rubber trees. Moreover, this kind of plantation is also conducive to soil and water conservation and soil fertility maintenance. Thus, it can give a sustained higher production of rubber. |
