摘要
本文提出农业生态系统结构的3级指标体系及其指标内各成分的折算问题。同时结合浙江省典型农户的调查,探讨对原始数据目的旨在统一量纲和缩小指标间数最级悬殊的有效转换方法。
Proper structural index systems at three levels for classifying agroecosystem and methods for converting various indices into same unit were discussed in this paper. Based on the data obtained from some typical ecological farms in different areas of Zhejiang Province,5 data transformation techniques and effective methods for unifying the dimension of various indices and reducing great disparities in quantity among the indices were studied and discussed.
