摘要
制定高标准农田生态化改造的内容与关键技术、建立专门化的评价指标体系是推动农业绿色转型并实现高质量发展的有效途径.总结了各地开展高标准农田生态化改造的实践经验并梳理了现有研究成果.高标准农田生态化改造主要集中于田、土、水、路、林5个方面,包括打造生态型田块,培育生态型土壤,搭建生态型排灌系统,铺设生态化道路网络,以及构建生态保护网络.同时,结合现有评价规范和实际工作需求,建成一套应用性强、敏感度高、特色性足的基于过程的评价指标体系,从资源高效、节能减排、生态涵养和安全优质4个维度评价改造成效.最后,从创新投入机制、制定技术规程和建立评价规范等方面提出保障高标准农田生态化改造的相关建议.
Abstract
Developing the content and key technologies of well-facilitated farmland ecological upgrading,as well as establishing a specialized evaluation indicator system,are effective approaches to promote agricultural green upgrading and achieve high-quality development.This paper summarized the practical experience of local well-facilitated farmland ecological upgrading and reviewed existing research achievements.The ecological upgrading of well-facilitated farmland primarily encompassed 5 aspects of field,soil,water,road,forest,including the construction of ecological field blocks,cultivation of ecological soil,establishment of ecological irrigation and drainage systems,laying of ecological road networks,and construction of ecological protection networks.Meanwhile,by combining existing evaluation standards and practical work requirements,a comprehensive evaluation indicator system was developed,which was highly applicable,sensitive,distinctive and process-based,to assess the upgrading effects from 4 dimensions:resource efficiency,energy conservation and emission reduction,ecological conservation,and high-quality safety.Finally,suggestions were provided regarding innovative investment mechanisms,formulation of technical procedures,and establishment of evaluation standards to ensure the ecological upgrading of well-facilitated farmland.
