摘要
在调查研究不同类型的农户生态系统的基础上,本文采用优势度和稳定指数两个指标对四种不同类型的农户生态系统结构进行定量评价,并分析比较四类农户生态系统的能量产投比和经济效益。结果表明,这两个指标能定量地衡量各种类型农户生态系统的均衡性和稳定性,可以对农户生态系统结构优劣进行评价。
On the basis of the Investigation and analysis of different family household ecosystems, the dominance and stability indexes of complcxed systems were introduced in four typos of family household ecosystem to evalmti- qviantitatively the structure and to analyze and compare energy input-output as well as economic efficiencies. The results showed that the dominance and stability indexes could effectively quantify the equipollence and stability of ecosystems and could be used as main parameters to cvalutc the ecological structure.
