摘    要:本文运用调查方法,定量分析不同地貌类型区(山区丘陵、山前平原、低平原和滨海平原)表征村落生态系统结构和功能的几个指标的变化。结果表明:1.平原地带的庭院面积大于丘陵山区,主要是由于地形及土地利用政策的影响;2.庭院经济收入取决于庭院面积与经营程度;3.村落规模、密度的变化与农田生产力变化一致;4.适当增加村落密度,控制村落规模,有利于缩短耕作半径,提高劳动生产率。

关 键 词:村落生态系统  庭院面积  庭院收入  人口密度  农田生产力  耕作半径

Abstract:In this paper,the changes of index represt-ing the structure and function of village ecosystem in different geomorphologic regions (mountainous and hilly re- gion,piedmont plain, low plain and coastal plain) are quantitatively analyzed through investigation. The results show that courtyard area of plain belt is larger than that of mountains, which is mainly resulted from topography and land utilization policyi(2)courtyard economic income is depended on courtyard area and management hevel t (3) the changes of village scale and density is consistent with farmland productivity; (4)properly increasing village density and conrolling village scale are favourable to. shorten cultivation radium and raise labour productivity.
Keywords:village ecosystem  courtyard area  courtyard e- conomics  population density  farmland productivity  culti- vation radium
