摘要：

以山区村———河南省巩义市吴沟村 81户 4 82块农田的调查数据为依据 ,研究了地形对山区农村人地关系的影响。结果表明 ,山地农田系统人工能量的转换效率随地块高程的增加而呈降低态势 ,但农田的轮作特点和潜力的挖掘程度 ,又影响这种变化趋势 ;坡度与农田系统能量产投比显著负相关 ,坡向、坡度、坡位对农田能量的投入产出也有一定影响。以农田人工能量投入产出关系衡量 ,山区农民对自然条件利用的过程 ,表现出明显的经验型利用特征。条件适宜区农田的过度利用 ,使得人工能源的投入产出效率明显下降 ;而其他高程和坡度的一些农田 ,仍有较大的利用空间。农田系统属半人工生态系统 ,具有很强的自然、人工特征 ,有助于我们在微观层面上研究人与地的关系

Abstract:

A micro-level input-output analysis on farmland is important in understanding the man-land relationship in rural areas, particularly in the mountainous regions. This paper is based on a survey undertaken in a small rural mountainous village in Wugou of Gongyi city, Henan Province in April 2003. The survey covers 482 plots of farmland from 81 households. Data collected include 50 attributes for each plot. The amount of input and output is simplified by converting into energy equivalent. By employing a revised Cobb-Douglas production function (Y=AX α), the input and output analysis based on the survey data finds the following results. (1) The energy input-output ratios, as well as energy transfer efficiency in the farmlands declines along with the increase in elevation of the lands. An exception is those fields close to the residential area of the village site. (2) A significant negative correlation between slope gradient and energy input-output ratios exists. But analysis based on three classifications of slope gradient further reveals that the farmlands with medium- and lower-slope gradient have the highest ratios in energy production. (3) Other factors of landform description, such as slope aspects, slope position and slope curvature also affect energy transfer in various ways. These facts imply that farmers in the rural mountainous areas heavily rely on their past experience in utilizing natural resources. There is a big room for improving the man-land relationship.
