摘要/Abstract

摘要： 围绕海南岛橡胶林急需改造的重大需求，进一步提高橡胶林复合经营模式生态系统的碳密度，选取橡胶（Hevea brasiliensis）+火力楠（Michelia macclurei）、橡胶+益智（Alpinia oxyphylla）、橡胶+草豆蔻（Alpinia katsumadai）、橡胶+斑斓（Pandanus amaryllifolius）、橡胶+可可（Theobroma cacao）、橡胶+咖啡（Coffea arabica）、橡胶+肉桂（Cinnamomum cassia）等海南岛7种典型橡胶林复合经营模式为研究对象，通过分析植被、凋落物和土壤碳密度，对橡胶林不同复合经营模式生态系统碳密度进行了估算。结果表明：（1）相比橡胶纯林，儋州和文昌地区橡胶林复合经营模式生态系统碳密度显著提高。（2）儋州地区橡胶林复合经营模式生态系统碳密度从高到低分别为：橡胶+肉桂模式（213.3±9.45 t·hm^-2，固碳潜力为19.73 t·hm^-2）；橡胶+益智模式（201.51±15.29 t·hm^-2，固碳潜力为7.94 t·hm^-2）、橡胶+斑斓模式（200.37±9.60 t·hm^-2，固碳潜力为6.80 t·hm^-2）和橡胶+咖啡模式（199.23±8.46 t·hm^-2，固碳潜力为5.66 t·hm^-2）。（3）文昌地区橡胶林复合经营模式生态系统碳密度显著提高，其模式为：橡胶+火力楠模式（198.07±18.37 t·hm^-2，固碳潜力为38.76 t·hm^-2）。这可为热带地区橡胶林改造和复合经营模式固碳增汇提供理论依据和技术支持。

Abstract: Addressing the urgent need to transform rubber plantations pattern in Hainan Island and solve the problem of enhancing ecosystem carbon density in rubber plantations under compound management patterns, seven typical compound management patterns of rubber plantations in Hainan Island were selected as research objects, including Hevea brasiliensis + Michelia macclurei, Hevea brasiliensis + Alpinia oxyphylla, Hevea brasiliensis + Alpinia katsumadai, Hevea brasiliensis + Pandanus amaryllifolius, Hevea brasiliensis + Theobroma cacao, Hevea brasiliensis + Coffea arabica, and Hevea brasiliensis + Cinnamomum cassia. The results showed that: (1) Compared with pure rubber plantations, ecosystem carbon density of rubber plantations under compound management patterns in Danzhou and Wenchang were significantly increased. (2) In Danzhou, ecosystem carbon density under compound management patterns followed the order of Hevea brasiliensis + Cinnamomum cassia pattern (213.3 ± 9.45 t·hm^-2, with a carbon sequestration potential of 19.73 t·hm^-2); Hevea brasiliensis + Alpinia oxyphylla pattern (201.51±15.29 t·hm^-2, with a carbon sequestration potential of 7.94 t·hm^-2), Hevea brasiliensis + Pandanus amaryllifolius pattern (200.37±9.60 t·hm^-2, with a carbon sequestration potential of 6.80 t·hm^-2), and Hevea brasiliensis + Coffea arabica pattern (199.23±8.46 t·hm^-2, with a carbon sequestration potential of 5.66 t·hm^-2). (3) In Wenchang, ecosystem carbon density of rubber plantations under the Hevea brasiliensis + Michelia macclurei pattern was significantly increased (198.07±18.37 t·hm^-2, with a carbon sequestration potential of 38.76 t·hm^-2). These results provide a theoretical basis and technical support for forest transformation and carbon sequestration of rubber plantations under compound management patterns in tropical areas.
