大中型农场生态经济评价指标及评价方法

本文在对几个典型大中型农场现状调查基础上，根据生态经济评价指标体系的确定原则．确立了评价农场生态经济现状的指标体系。同时，为消除不同地区间农场的资源差异，便于不同农场间的相互比较，又采用ＦＡＯ提供的生态区域法和主成分分析法对指标体系进行指标筛选，并在总结前人研究的基础上，结合农场实际，建立了能综合反映农场生态经济现状的评价方程Ｙ＝１０Ｘ＿１＋０．０７５（Ｘ＿２＋Ｘ＿３）＋０．６Ｘ＿４＋５（Ｘ＿５＋Ｘ＿６）＋２Ｘ＿７＋０．１５Ｘ＿８＋０．００１５Ｘ＿９，并把它运用到农村的生态经济评价中。本文确定的评价指标和评价方法，不仅适用于不同地区的各类农场，也适用于我国不同地区的各类农村。对我国不同地区不同类型的生态系统生态经济评价具有普遍的指导意义。

The ecolonomic evaluation criteria and assessment method forlarge and middle size farms

On the basis of the status quo investigations inseveral typica large and middle size farms and defining princi-ples of ecolonomic evaluation index system.The index systemfor assessing the ecolonomic status of farm was established.The ecological regionization method provided by FAO andmain component analysis method were applied to screening in-dex from index system. On the basis of summarizing the previ-ous research results and in combination with the practical situ-ation of farms ,an evaluating equation(Y=10X_1 0. 075(X_2 X_3) 0.6X_4 5(X_5 X_6) 2X_7 0.15X_8 0.0015X_9),whican con comprehensively reflect the present ecolonomic sta-tus of farms,was developed and applied in the assessment ofrural ecolonomics.The assessment indexes and methods de-fined in the study can be applied not only in various farms,butalso in various countryside of different regions in China.ItpIays a guiding role in the ecolonomics assessment of varioustypes of ecosystems in different regions of China.
