| 摘 要： | 论文采用PSR框架构建评价指标体系,利用云理论分别构建定量指标与定性指标的云模型,对农用地生态环境进行评价。以广东省新兴县为例,得出新兴县农用地生态环境分值为0.75,农用地生态环境良好。并将云理论与模糊规则进行对比,得出新兴县农用地生态环境分值分别为0.75和0.70,两者结果差异不大,但是结果表明云理论能完整表达评价问题中的不确定性,避免模糊规则中隶属度函数确定繁琐的问题。 |

| Abstract: | In view of the status quo that few researches have been made on ecological environment evaluation of agricultural land,this paper adopts PSR framework to construct index system of evaluation,and employs the cloud theory to establish cloud models of quantitative indexes and qualitative indexes respectively so as to evaluate ecological environment of agricultural land.Taking Xinxing County as an example,the evaluation score is 0.75 representing good ecological environment in Xinxing.The result is reasonable a... |
| Keywords: | ecological environment of agricultural land cloud theory PSR framework fuzzy rules Xinxing County |
