摘　　要：生态环境改善是水土保持治理成效的重要体现。研究表明:黄土高原水土流失治理后,植被覆盖率显著提高,生态环境明显改善。物种数量及丰富度显著增加,种群间建立了新的生态平衡关系。建议:进一步开展黄土高原水土保持重点治理区生物多样性变化研究,制定生物多样性监测技术标准体系,完善生物多样性保护相关政策制度,为黄土高原地区生态环境改善效果和水土保持有效性评估奠定基础。The improvement of ecological environment is an important manifestation of the effectiveness of soil and water conservation management.The research shows that the vegetation coverage rate has significantly increased,the ecological environment has significantly improved,the number and richness of species have significantly increased,and a new Balance of nature relationship has been established between populations.Suggestion:Further carry out research on biodiversity changes in key areas for soil and water conservation in the Loess Plateau,develop a biodiversity monitoring technology standard system,improve policies and systems related to biodiversity protection,and lay a foundation for the evaluation of the effectiveness of ecological environment improvement and soil and water conservation in the Loess Plateau region.
