Comparative Analysis of Village Ecosystem in Different Geomorphologk Regions

In this paper,the changes of index represt-ing the structure and function of village ecosystem in different geomorphologic regions (mountainous and hilly region,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.
