南方丘陵山地农业具有耕地细碎化的典型特征，土地细碎化条件下的紧凑型种植模式是普遍现象，细碎化耕地条件的机械化依靠小型作业机械。为描述作业机械在细碎化耕地条件下的行为特征，田间调查发现，快速进退、频繁转向、循边收获、移动困难等是细碎化耕地条件机械化田间作业的显著特点。小型收割机在南方的普遍应用状况表明丘陵山地作业机械的性能评价需要以土地适应性为主导的评价指标。

A typical characteristic of the southern China hilly and mountain region agriculture is the fragmentation of arable lands, under which condition the compact mode of crop planting was widespread in the south China .Mechani-zation of the fragmented farming land production depends on the utilization of small -type field working machineries .A field investigation was conducted to illustrate the behavioral characteristics of the small -type agricultural machinery working in the fragmented farming land .Results found that quick forward and backward movement shifting , frequent turning, field edge contouring, difficult intra-field maneuvering were the marked characteristics of small-type harvest-ers working in fragmented arable lands .The widespread use of small-type harvesters in the south China showed that assessment of the adaptability of agricultural machineries should be based on land suitability as the main leading eval -uation index .
