| 摘 要： | 对福建省南安市丘陵区疏林地小流域生态修复效果进行系统的研究评价,以期为闽东南沿海丘陵区生态修复提供科学依据。结果表明:经过近15年的生态修复,植被覆盖度从30%～50%提高到91.4%～95.8%,群落呈现多样性、稳定性,林分水源涵养能力提高了56.27%～76.86%。土层土壤结构得到改善,土壤肥力得到提高。10年平均土壤侵蚀模数减少2054～2149t/(km2 ·a),水土流失得到控制。

| Abstract: | The evaluation of natural eco-restoration of opening forest watershed in Nan'an was systematically studied. Results showed that after 15-year natural eco-restoration, vegetation cover rate was increasing from 30%～50% to 91.4%～95.8%, community was diversified and stable. The water conservation capacity of forest had increased by 56.27%～76.86%, soil structure and soil fertility was improved greatly. Average soil erosion modulus decreased by 2054～ 2149t/km2·a and soil erosion was controlled. |
