摘要
本文以重庆市为例,构建了区域的农业生态系统综合评价指标体系,运用层次分析法计算各项指标权重值,结合归一化指标数值,得出其生态、社会、经济子效益及综合效益分值,在此基础上,综合分析评价了重庆市农业生态系统,并提出了实现当地可持续农业的建议。
In this paper , Chongqing was elected as a study case. Firstly, the comprehensive evaluation index system about the regional agroecosystem was built. Secondly, the analytic hierarchy process was adopted to confirm the weights of the indices. Then, combined with the value of the indicator data normalized, the score of ecological, social, economic benefits and integrated benefit was calculated. Finally, according to these results,the agro-ecosystem in Chongqing was analyzed and evaluated in this paper ,and some proposal about sustainable agriculture was put forward.
