【摘要】 高标准农田是近年来我国新提出并大力倡导的现代农业发展模式,目前对高标准农田水利工程环境影响后评价,尚未形成一套合理适用的指标体系。运用AHP法和模糊综合评价法进行高标准农田水利工程环境影响后评价指标体系研究,选取水环境、土壤环境、生态系统、人居环境4方面作为准则层,提出氧平衡因素化学耗氧量(COD)、地下水埋深、排水设施完善程度等51项指标。更多还原

【Abstract】 High standard farmland is a modern agricultural development mode recently advanced and strongly advocated in China.However,the current post-evaluation of environmental impact of high standard irrigation and drainage schemes has not formed a set of reasonable and applicable index system.In this paper,the AHP method and fuzzy comprehensive evaluation method are applied to study the post-evaluation index system for environmental impact of high standard irrigation and drainage schemes.Four respects,including water environment,soil environment,ecological systems and human settlements environment,are selected as the rule layer,and 51 indicators,such as the oxygen balance based chemical oxygen demand(COD),the depth of groundwater level,the perfection degree of drainage facilities,et al.,are finally developed in this paper.更多还原
