针对海南热带雨林林分特征，提出了新的测度指标体系，对热带雨林树木生长及其竞争的关系进行了研究。结果表明，所提出的生长竞争测度指标能客观地反映林木生长势态，较大地提高了生长模型的估计精度。该研究为进一步揭示热带雨林生长规律，研究稳定、持续的生态系统提供了理论基础。
Aiming at the characteristics of tropical rain forest in Hainan Province, a new index system of measure was put forward to study the relationship between the growth and competition of tropical rain forest trees. The results show that the proposed measure of growth competition can objectively reflect the forest growth state and greatly improve the estimation accuracy of the growth model. The study provides the theoretical basis for further revealing the laws of the growth of tropical rain forests and for studying stable and sustainable ecosystems.
