边坡植被重建效果评价:研究进展与展望

Evaluation of slope re-vegetation effect:Research progress and prospect

边坡植被重建是开展生态修复的重要工作,对边坡植被重建效果进行评价具有重要意义。本文从评价指标体系构建、评价指标数据获取和相关标准规范等方面总结边坡植被重建效果评价的研究进展;重点对防护性能、土壤状况、植被状况、景观效果、综合效益五个方面的评价指标进行了梳理,将边坡植被调查方式总结为人工实地调查、卫星遥感解译、无人机航拍三个发展阶段。针对目前边坡植被重建效果评价中存在的缺少定量评价数据、缺少信息技术支撑、缺少持续追踪监测、缺少工程实践互馈等问题,提出未来相关工作与研究应朝着数据定量化、技术现代化、监测长效化、工程应用化的方向发展。

Vegetation reconstruction on the excavated slope is an important step of ecological restoration.Therefore,evaluating the effects of slope vegetation reconstruction is of great significance.Here,we reviewed the research progress in the evaluation of slope re-vegetation effect,specifically in the construction of evaluation index system,the acquisition of evaluation index data,and the relevant standard specifications.The evaluation indices of protection performance,soil condition,vegetation condition,landscape effect and comprehensive benefit were reviewed.The methods of slope vegetation survey could be divided into three development stages:manual field survey,satellite remote sensing interpretation,and aerial survey by unmanned aerial vehicle(UAV).Problems in the evaluation of slope vegetation reconstruction effect,including lack of quantitative evaluation data,lack of information technology support,lack of continuous tracking and monitoring,lack of mutual feedback of engineering practice,were summarized.The directions of data quantification,technology modernization,long-term monitoring,and engineering application are proposed as the main topics in the future research.
