【目的】

以四川省筠连县国有林场内杉木/檫木林下套种方竹的复合经营林分为研究对象，通过对比杉木+方竹、檫木+方竹复合林与杉木、檫木、方竹纯林的土壤养分特征，探讨林竹复合经营对土壤养分的影响效应，以期为川南丘陵区森林土壤提质增效提供科学依据。

【方法】

通过对杉木+方竹、檫木+方竹复合林分以及杉木、檫木和方竹纯林林分土壤养分进行分析测定，并采用Nemerow法进行综合评价，探讨复合经营对森林土壤养分的影响。

【结果】

1）复合经营模式显著提升了土壤养分含量。在基础养分方面，杉木+方竹、檫木+方竹复合林的土壤有机质含量分别为77.20±3.07 g/kg和82.57±16.43 g/kg，较杉木纯林53.97±6.08 g/kg和檫木纯林72.17±7.40 g/kg分别提高了43.1%和14.4%；2）在有效养分层面，檫木+方竹复合林的水解性氮、有效磷、速效钾含量分别为268.00±43.21 mg/kg、3.42±1.16 mg/kg、145.67±20.67 mg/kg，较檫木纯林分别提高16.0%、10.7%和20.7%；3）土壤综合评价显示，檫木+方竹复合林的Nemerow综合指数为1.46，森林土壤养分等级从中等提高为良。

【结论】

林竹复合经营通过物种间的生态互补效应，相比纯林经营有效改善了土壤养分状况，其中檫木+方竹复合林分在提升土壤有机质含量、促进氮磷钾养分积累及提高有效性养分比例方面表现最优。本研究不仅丰富了林竹复合经营的土壤生态学理论，可为川南丘陵退化林地的生态修复和可持续经营提供实践参考。

【Objective】

This study focused on the soil nutrient characteristics of the mixed forest of Cunninghamia lanceolata/Sassafras tzumu with Chimonobambusa quadrangularis planted under the canopy in the state-owned forest farm of Junlian County, Sichuan Province. By comparing the soil nutrient features of the mixed forests of Cunninghamia lanceolata + Chimonobambusa quadrangularis and Sassafras tzumu+Chimonobambusa quadrangularis with those of the pure forests of Cunninghamia lanceolata, Sassafras tzumu and Chimonobambusa quadrangularis, the study aimed to explore the effect of forest and bamboo compound management on soil nutrients, and to provide a scientific basis for improving soil quality and efficiency in the hilly areas of southern Sichuan.

【Method】

By analyzing and determining the soil chemical properties of the compound forest stands of Cunninghamia lanceolata + Chimonobambusa quadrangularis, Sassafras tzumu + Chimonobambusa quadrangularis, the pure forest stands of Cunninghamia lanceolata, Sassafras tzumu and Chimonobambusa quadrangularis, using the Nemerow method for comprehensive evaluation of soil, the influence of mixed management on forest soil was explored.

【Result】

1) The mixed management significantly increased soil nutrient content. In terms of basic nutrients, the soil organic matter content of the mixed forests of Cunninghamia lanceolata+Chimonobambusa quadrangularis and Sassafras tzumu+Chimonobambusa quadrangularis was 77.20±3.07 g/kg and 82.57±16.43 g/kg, respectively, which was 43.1% and 14.4% higher than that of the pure forests of Cunninghamia lanceolata (53.97±6.08 g/kg) and Sassafras tzumu (72.17±7.40 g/kg); 2) In terms of available nutrients, the contents of water-soluble nitrogen, available phosphorus and available potassium in the mixed forest of Sassafras tzumu+Chimonobambusa quadrangularis were 268.00 ± 43.21 mg/kg, 3.42 ± 1.16 mg/kg and 145.67 ± 20.67 mg/kg, respectively, which were 16.0%, 10.7% and 20.7% higher than those of the pure forest of Sassafras tzumu; 3) The comprehensive evaluation of soil showed that the Nemerow comprehensive index of the mixed forest of Sassafras tzumu+Chimonobambusa quadrangularis was 1.46, and the forest soil nutrient grade was improved from medium to good.

【Conclusion】

The mixed management of forest and bamboo effectively improved the soil nutrient status through the ecological complementary effect among speciess compared with pure forest management. Among them, the compound forest of Sassafras tzumu+Chimonobambusa quadrangularis performed best in increasing soil organic matter content, promoting the accumulation of nitrogen, phosphorus and potassium nutrients and improving the proportion of available nutrients. The research results not only enriched the soil ecological theory of forest-bamboo mixed management, but also provided practical references for the ecological restoration and sustainable management of degraded forest land in the hilly areas of southern Sichuan.
