Research on Content and Evaluation Methods of Ecological Upgrading of Well-facilitated Farmland
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.
